Philaenus spumarius is quite common and widespread. The species' original distribution was restricted to the Palearctic realm. They are present in most of Europe, in North Africa, in part of Russia, in Afghanistan, and in Japan. They have also been introduced in North America.
This is a very eurytopic species, meaning that it can tolerate a wide range of environmental factors and exist in many different habitats (parks, meadows, gardens, etc.). It lives in almost all open land habitats and in open forests. It is absent only in very wet and very dry habitats.


The species reaches a body length of 5–7 millimetres (0.20–0.28 in). Most females are slightly larger than males. In these polymorphic insects, the coloration of the body is very variable (about 20 different colors are known). Usually, they are yellowish, brownish, or black, with brighter patches on a dark background, but also with dark markings on a lighter background.


The most common modes of locomotion are running and flying, but the most striking is their strong jumping ability, which is useful for escaping from predators. When jumping, the hind leg tarsal spines and spine hairs are embedded into the material the animal is jumping from, typically a plant, and provide the purchase needed for a lateral jump - confirmed with scanning electron micrographs. X-ray spectroscopy revealed that the darker coloured sclerotized tips of the spines, the last 6/100ths of a millimetre or so, contain zinc.


The seasonal nature, the phenology, of the species' life cycle varies because of the wide range of climatic conditions it can tolerate, but remains similar. In a temperate climate, the females lay eggs at the end of the summer. The eggs are laid singly or in groups (1 to 30, average 7
) on the food plants of the larvae. Egg-laying is triggered by a single female, which can produce up to 350–400 eggs. In unfavorable climatic periods, froghoppers can survive in the form of eggs.
Eggs are white with an orange spot; this spot becomes darker and larger if the egg is fertilised, approximately 1mm long and 0.3mm wide.
The larvae, also called nymphs, hatch after about 20 days and develop through five stages, known as instars.
The larvae are well known for the self-generated foam nests which can be observed during spring in meadows (especially on cuckoo flowers, Cardamine pratensis, and broom, Genista, species). The larvae in the foam nests are largely protected from predators and also get the necessary moisture for the appropriate development and temperature, so their mortality remains low even in bad weather. The larval stage lasts about 50 days. The adults leave the foam nest only when it is completely dried. This takes about ten days. The females mate soon after.
Froghoppers are polyphagous, their host plant specificity is low, so that they can feed on a variety of plants, mainly grasses (Poaceae species), reed plants (Juncaceae species), herbs and sometimes trees (including the olive tree, where the species has been identified as spreading Xylella fastidiosa, the bacterium associated with Olive quick decline syndrome). They have been identified on over 170 host plants.


Philanthus gibbosus is a member of the family Crabronidae of wasps within the order Hymenoptera. Below is a cladogram that is based on a 2012 study conducted by Debevic et al. and published in the journal Zoologica Scriptica. The study investigated molecular phylogeny to reveal that the bees, Anthophila, came from within the family Crabronidae, meaning the family is, therefore, paraphyletic.
The genus Philanthus contains about 135 other species in addition to P. gibbosus.
The predation habits of the family Crabronidae shed light on the question whether bees or wasps came first. Based on this evidence, bees are a lineage of pollen-collecting wasps that descend directly from a group of predatory wasps in Crabronidae.


P. gibbosus is a small and robust wasp that is about 10–12 mm in length. P. gibbosus has an especially broad head and a coat of chitin that is shiny black with yellow spots on the head and yellow stripes on the abdomen and thorax. There are very large, deep punctures on the abdomen of P. gibbosus, making the species easy and distinct to identify in comparison to other members of the genus Philanthus.


While the general range of P. gibbosus size is 10–12 mm in length, females are usually closer to the smaller end of the scale. Female P. gibbosus have more yellow coloration on the head than do the males of the species.


The males of P. gibbosus resemble the females very closely, but the most notable difference is the significantly reduced presence of yellow spots on the head. This is opposite of the usual pattern observed within the order Hymenoptera. Most commonly, the males in hymenopteran species have an excess of yellow spots on the head while females lack spots.


In general, P. gibbosus goes through two generations of colonies a year.


P. gibbosus is a solitary wasp that nests in the ground. Several individuals have been observed to cohabit a single burrow at a time. However, there is evidence that suggests that while females tend to occupy the parental nest for a mere several days of their lives, the males will sometimes inhabit the nest for their entire life. After the few days in their original nest, the females will disperse to new nests. However, one single female may continue to inhabit and expand the original nest. On very rare occasions, two females may provision the original nest at the same time for a very brief period. Evidence suggests that P. gibbosus may be representative of a unique stage in presociality in which temporary communal nesting occurs at certain phases of the nesting cycle, in spite of the species' usual solitary living.


Because P. gibbosus is a solitary wasp species, there is not much need for intra-species communication. However, when mating, males are responsible for marking the territory surrounding the nest with pheromones as a means of warding off other competing males from mating with the female in the nest. These pheromones are the main form of intra-communication, specifically between the different, individual males of P. gibbosus.


During the main season of its activity, May through September, the entrance to the nesting sites of P. gibbosus can be characterized by the scattered heaps of sand or soil around their supporting structure, usually bricks or tree roots. The sand heaps are very low and spread out. In building these sand heaps, females can be observed backing out of the burrow with moist sand or soil that is spread around into the heaps using jerks of her front legs. While burrowing, P. gibbosus stands on its hind legs. In order to dig the actual burrow, P. gibbosus uses its tarsi and mandibles to dig a shaft that is at least two feet in length. The shaft culminates in an oval shaped cell in which eggs are provisioned. Other oval shaped cells line the shaft which are smaller in size and contain the skeletons of other bees that were killed and fed to the larvae as nutrients.


P. gibbosus is a part of a mimicry group with a wide variety of other wasps that also exhibit black and yellow banding and coloring. It has been observed that mimicry is high in spring and early summer, generally absent in midsummer, and infrequent in late summer. This implies that some members of the mimicry group, including P. gibbosus, may be selected to avoid the midsummer season when insectivorous birds are abundant and have not yet learned to avoid the models which the mimics resemble. The colony cycle of P. gibbosus lines up with this scheduling in such a way that minimizes the amount of predation the species faces.


While P. gibbosus does not camouflage with its surroundings, it exhibits a black and yellow chitin coating that serves as a warning to other predatory species. This coloration pattern that is characteristic of many species of wasps is a somewhat universal sign that an organism stings and should, as a result, be avoided in predation.


P. gibbosus is notable in that it stings its prey in a membranous location on the ventral surface of the abdomen where the venom is quick to incapacitate many major, voluntary muscles. The paralyzing effect of the injected venom is likely due largely in part to a block of the somatic neuromuscular transmission. It has also been established that the venom is not limited exclusively to the natural prey, the honey bee, but also in many other insect species belonging to different orders, including spiders. Only P. triangulum  itself and a digger wasp that preys on P. triangulum are immune to the venom. However, the sting does not kill the prey. The prey may attempt to sting in return, but P. gibbosus always grabs the prey in such a way that the well-armored portions of the body are presented, thus protecting P. gibbosus from a retaliation by the prey. P. gibbosus then carries its paralyzed prey back to an oval cell in its nest for temporary storage until it is later used in the laying of an egg.


Although P. gibbosus feeds on insects, they are also prey for certain insects as well. Predatory insects for P. gibbosus include praying mantis, robber flies, and dragonflies. Sometimes, smaller P. gibbosus individuals will be preyed on by larger wasps. Some birds will even regularly consume wasps. A few examples of birds that prey on P. gibbosus include sparrows, wrens, and summer tanagers. In general, these birds normally exclusively hunt solitary wasps, making P. gibbosus an ideal target. Moreover, the birds avoid disturbing P. gibbosus near their nests.


P. gibbosus has a sting that is painful and menacing enough to deter most potential predators. P. gibbosus's black and yellow coloring serves as a warning to other organisms, as that color pattern often indicates a dangerous species. Additionally, the burrowing behavior of P. gibbosus provides the species with a suitable hiding spot to avoid predators. Because the burrows are so far into the ground, usually around two feet, P. gibbosus is able to avoid predation by remaining in its burrow.


P. gibbosus is most notably parasitized by a nest parasite, Senotainia trilineata, a Miltogrammid fly. P. gibbosus utilizes a flight pattern in which it flies over the nest from above as a means of surveying its nest for the parasite, one that is different from other species of the same genus.


While not much research has been done on which specific pathogens affect P. gibbosus, Streptomyces have been observed to be antibiotic-producing symbionts, which have been suggested to potentially defend their wasp hosts from a variety of pathogenic microbes. This array of phylogenetically diverse and chemically prolific Actinomycetota that has been observed in P. gibbosus suggests that these types of insect-associated Actinomycetota can serve as a source of natural products of pharmaceutical interest for other species.


P. gibbosus is a pollinator of some plants. It has been observed pollinating carrot plants.


P. gibbosus presents a challenge for beekeepers. Because of its tendency to prey on honey-producing bees, P. gibbosus has been known to attack beekeeping sites. This complicates the process of beekeeping and hinders honey production.


The bare-faced ibis (Phimosus infuscatus), also known as the whispering ibis, is a species of bird in the family Threskiornithidae, in the monotypic genus Phimosus.


It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Paraguay, Suriname, Uruguay, and Venezuela.


The bare-faced ibis is either dark brown or a blackish color. It is called the bare-faced ibis because it does not have any feathers on its face. It has a long decurved bill with a pinkish to reddish brown colour. The skin on its face is usually a reddish color, and it also has long orange colored beak with pink legs. The total length of the ibis ranges between 45 and 50 cm.


The bare-faced ibis forages in most soil and along the edges of standing water. Its diet consists of insects, worms, clams, and other small invertebrates.


The bare-faced ibis occurs in open areas such as wet meadows, savannas, marshes, and rice fields. The ibis is usually near sea level but was recorded in Venezuela and Colombia. When an ibis is about to lay its eggs it builds a nest out of sticks and twigs to put them in and it will lay between 2 and 5 eggs and will then sit on them for protection purposes for up to three weeks.


Bare-faced ibises are usually seen in large flocks of their own species or with other species of ibis, sometimes even found with domestic animals. They live in close range neighboring amongst other flocks of ibis, typically known for the closest living habitats that range from being 100 meters away from the nearest neighbor. They are not very territorial towards other ibis birds, and rarely found alone, but most of the time the aggression is shown from food robbery from another ibis or animal. Regarding sexual behavior, the Bare-Faced ibis is less aggressive amongst other species of ibis. The males have a larger bill than the females relative to their body sizes, and sexual selection is not as intense as it is in other species. They share nests with other species as well.


Phleum alpinum is a species of grass known by the common names alpine cat's-tail, alpine timothy and mountain timothy.


Phleum alpinum has a circumboreal distribution, inhabiting northern areas of the Northern Hemisphere, as well as extending down through the Americas to southern South America. It can be found on islands in the subantarctic region such as South Georgia Island, on which it is one of the most common plant species.


Phleum alpinum is a perennial bunchgrass forming loose clumps 20 to 60 centimeters tall. The inflorescence is a cylindrical to oval mass of spikelets up to 6 centimeters long and 1.2 wide.


Nosoderma diabolicum (formerly Phloeodes diabolicus), common name: diabolical ironclad beetle, is a beetle of the Family Zopheridae. It is found in deserts of western North America, where it lives on fungi growing under tree bark. It is flightless and has a lifespan of two years, compared to the weeks or months long lifespan of typical beetles.
This beetle is noted for its durability. Its thick, densely layered and interlocking elytra, connected to the ventral cuticle by complex lateral support structures, are able to support maximum force of 149 newtons, approximately equal to the force exerted by 15 kilograms or 33.069 lbs.


These inch-long beetles have the potential for extremely long lifespans due to their structure and shape.  Many beetles have a rounded body, but the diabolical ironclad is different, having a flat shape and low-to-the-ground profile makes these beetles extremely hard to squash.  The compression is not focused on one spot but rather spread across the shell evenly distributing the force over the whole shell.  The shell provides many issues for entomologists trying to display their specimen.  The beetles cannot be mounted normally using stainless steel pins, but rather they need to drill holes in the shell where they desire to place the pin.
Utilizing a jigsaw-like layering of their joints and appendages provide stability to withstand such extreme forces. This is done by layering multiple different scales of different sizes, ranging from microscopic to visible sizes, providing exceptional mechanical strength. The jigsaw pattern seen is a multilayered exoskeleton, including a waterproof epicuticle, an underlying exocuticle and lastly an internal endocuticle. In each of the cuticles, polysaccharide α-chitin combine with proteins to form fibers within each layer. These fibers are twisted and stacked upon each other creating a "helicoid" arrangement, forming laminated structures. This formation allows for strong, energy-absorbent and tolerant structures. Being energy absorbent the skeleton is able to deflect, twist and arrest crack propagation between each layer. The lack of flight allows the hardened elytra to be locked in place with the hindwings which aids the structure.  Using a compositional analysis it was found that the microstructure of exoskeleton is protein-rich and contains no inorganic structure (common in crustacean exoskeleton), while also containing a thicker endocuticle than other insects.
There are two main areas that allow the skeleton to endure such forces as much as 39,000 times its own body weight. The first is the connection between the two halves of the shell: the interconnections are zipper-like providing additional strength and are stiff and resist bending pressure.  The back of the beetle is not interlocked in the same way allowing the bottom halves to slide past each other, providing flexibility to absorb squishing compression.  The second area is the puzzle-like design that runs the length of the back connecting the left and right side.  Protrusions called blades fit together like jigsaw pieces, glued together by proteins aiding in damage resistance.  The connection allows the blades to absorb impacts without snapping.  The protection allows the beetle to be almost predator proof, denying most species the ability to break the shell.


Phlomoides tuberosa (syn. Phlomis tuberosa), the sage-leaf mullein, is a perennial herbaceous flowering plant in the family Lamiaceae, native to China, Kazakhstan, Kyrgyzstan, Mongolia, Russia; SW Asia and Europe. Enlarged, tuberous roots give rise to erect stems to 150 cm bearing purple-red flowers.


Phytochemical analyses of Phlomoides tuberosa leaves have found flavonoids apigenin, apigenin-7-O-glucuronide, luteolin, luteolin-7-O-glucoside, luteolin-7-О-glucuronide, orientin, isoorientin, phenylpropanoids acteoside (verbascoside), forsythoside B, decaffeoyl-acteoside, leucosceptoside A, marthynoside, neolignanes, iridoids sesamoside, 5-desoxy-sesamoside, shanzhiside methyl ester, lamalbide, 8-O-acetyl-shanzhiside, phloyoside I, chlorotuberoside, sterols, triterpenes oleanolic acid, ursolic acid.

The seed has yielded 11.8% of oil, including 3.3% gadoleic acid and some fatty acids containing the unusual allene group, 25.1% laballenic acid and 2.9% phlomic acid. The roots shown the presence of oligosaccharides raffinose, stachyose, verbascose, flavonoids luteolin, linarin, quercitrin, phenylpropanoids acteoside, isoacteoside (isoverbascoside), forsythoside B, chlorogenic acid, decaffeoyl-acteosyde, iridoids shazhiside methyl ester, 8-O-acetyl-shanzhiside methyl ester, 8-O-acetyl-shanzhigenin methyl ester, floyoside I, phlotuberosides I and II, phlorigidoside C, diterpenes (abietanes, labdanes).


This plant is grown in full sun, but may tolerate some shade. The cultivar 'Amazone' has won the Royal Horticultural Society's Award of Garden Merit.


The Kalmyks are said to have eaten the cooked root, calling the plant bodmon sok. Another source for Mongolia has the plant used as a folk restorative medicine against intoxication, tuberculosis, pulmonary and cardiovascular diseases and rheumatoid arthritis. Buryat lamas used some part of the plant to treat diarrhoea, eye and lung disease and as a sedative.


Phlox diffusa is a species of phlox known by the common name spreading phlox. It is native to western North America from British Columbia to the southwestern United States to the Dakotas, where it grows in many types of habitat, including rocky, high elevation mountain slopes. It is a very compact mat-forming perennial herb growing in cushions or patches of short, decumbent stems. The linear, lance-shaped, or needle-like leaves are no more than 1.5 centimeters long and are oppositely arranged in bundles on the short stems. The inflorescence is a solitary tubular flower around a centimeter long. It has a flat white or pale pink or blue corolla with five lobes each just under a centimeter in length.


Phlox diffusa is a perennial herb subshrub. Its matted to the ground no more than 8 inches tall and its stem is usually prostrate or decumbent to erect. Phlox diffusa has opposite simple pinnate needle like leaves. Flowers are quite showy and range from Lavender to pink in color. Flowers have five petals with a tubular corolla that is fused at the base.


Phlox diffusa prefers dry hillsides such as areas like rocky slopes and terrains such as alpine or sub-alpine or pumice fields.


Phlox diffusa is widely distributed throughout the western United States going as far east as Nebraska. It spreads northerly to British Columbia in Canada with its Southern limits being Southern California. Specific areas in United States are North Nevada, Idaho along with small areas of Montana and South Dakota along with Arizona, California, Colorado, Idaho, Montana, Nebraska, New Mexico, Nevada, Oregon, South Dakota, Utah, Washington, Wyoming and Nevada mountains.


Based on a study at Chowder ridge fell-view community the flower morphology of Phlox diffusa such as flora color and insect visitors dominated the methods they are pollinated. The study showed that due to early blooming of Phlox diffusa, butterflies and bumblebees visited the flowers less frequently than expected but still are considered major pollinators. Two minor pollinators for Phlox diffusa are Muscoid flies and Syrphid flies which both visited significantly less. Evidence from this study points to Phlox diffusa being an important nectar source for early season queen bumblebees.Phlox diffusa  is a perennial plant which blossoms early May through Mid August  which then goes dormant in November until next spring.


Phlox hoodii, the spiny phlox or carpet phlox, is a species of phlox. It is a plant of western North America, where it is a common flower in sagebrush country, mostly growing in dry lithosol habitats. It is among the first plants to bloom in spring, after the snow has melted. Its distribution extends from Alaska to Arizona. There are many subspecies.
This perennial herb is variable in morphology, but usually forms a tight mat or loose clump on the ground. The short stems emerge from a woody taproot and caudex unit and the plant form is no more than 13 centimetres (5 in) tall. The abundant tiny, sharp-pointed leaves are oppositely arranged and barely exceed one centimetre (1⁄3 in) long. The herbage is hairy in texture, the hairs short to long, woolly to cobwebby. The appearance of the plant is almost mosslike until blooming. The inflorescence is a solitary flower in shades of white, pink, or blue. It has a tubular throat about one centimetre (1⁄3 in) long spreading into a flat five-lobed corolla.


Phobetron pithecium, the hag moth, is a moth of the family Limacodidae. Its larva is known as the monkey slug.


One generation a year occurs in the north, but two or more happen in the southern United States.


The larva is distinctive, with no close analogues, although it may be mistaken for the shed skin of a hairy spider or leaf debris. It has nine pairs of curly projections or tubercles of varying lengths from the flattened body, each densely covered in hairs. The third, fifth and seventh projection are often longer than the others. The caterpillar has been reported to cause irritation to humans.  Like all limacodids, the legs are shortened and the prolegs are reduced to suction cups. The "arms" or tubercles can fall off without harming the caterpillar, aiding the larva in defense. The larvae are 1.5–2.5 centimetres (0.59–0.98 in) in length.
It is solitary and is not a very significant agricultural threat, but it is a common sight in orchards.


This species pupates in a cup-shaped cocoon with a circular escape hatch.


The adult moth has a wingspan up to 3 centimetres (1.2 in). The male has translucent wings, and the female is drab brown and gray, with yellow scales on her legs. The day-flying female is said to mimic a bee, complete with pollen sacs, and the male mimics a wasp.


Larvae live on the underside of the leaves of, and feeds on, a variety of deciduous trees and shrubs, such as apple, ash, birch, cherry, chestnut, dogwood, hickory, oak, persimmon, walnut, and willow.


The black-footed albatross (Phoebastria nigripes) is a large seabird of the albatross family Diomedeidae from the North Pacific. All but 2.5% of the population is found among the Northwestern Hawaiian Islands. It is one of three species of albatross that range in the northern hemisphere, nesting on isolated tropical islands. Unlike many albatrosses, it is dark plumaged.


Black-footed albatrosses are a type of albatross that belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used both against predators and as an energy rich food source for chicks and for the adults during their long flights. They also have a salt gland that is situated above the nasal passage that helps desalinate their bodies, to compensate for the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.
The specific epithet of nigripes is derived from two Latin words, niger meaning "black", and pes meaning "foot".


The black-footed albatross is a small member of the albatross family (while still large compared to most other seabirds) that has almost all black plumage. Some adults show white undertail coverts, and all adults have white markings around the base of the beak and below the eye. As the birds age they acquire more white at the base of the beak. Its beak and feet are also all dark. They have only the one plumage. They measure 68 to 74 cm (27–29 in), have a wingspan of 190 to 220 cm (6.2–7.2 ft), and weigh 2.6–4.3 kg (5.7–9.5 lb). Males, at an average weight of 3.4 kg (7.5 lb) are larger than females, at an average of 3 kg (6.6 lb).


The black-footed albatross, along with the laysan albatross and the rare short-tailed albatross, are the three species of albatross that range in the northern hemisphere, as opposed to the rest of the family which range from the Equator south. There are at least 12 known breeding locations, but 97.5% of the total population is found  colonially on the isolated Northwestern Hawaiian Islands, from Kure Atoll to Kaula Island, (such as Laysan, Midway, and the French Frigate Shoals). Small populations can be found on the Japanese islands of Tori Shima, Bonin, and Senkaku, and off the Mexican coast, primarily on Isla Guadalupe. They are extirpated from the Iwo Jima, Agrihan, Taongi Atoll, Marcus Island, Wake Island, and Johnston Island. Their range at sea varies during the seasons (straying farther from the breeding islands when the chicks are older or they don't have chicks) but they make use of great areas of the North Pacific, feeding from Alaska to California and Japan; however they do prefer the northeastern Pacific Ocean. They overlap greatly in breeding and feeding range with the other two species of northern albatross, although the other two will range further north into the Bering Sea than the Black-footed will. They have, on occasion, been sighted in the southern hemisphere.


Their vocalization will range from shrieks and squeals whilst fighting over food to bill-clapping, whistles, groans, and quacks while courting.


The black-footed albatross, like the rest of its family, forms long term pair-bonds that last for life. After fledging the birds return to the colony after three years, and spend two years building nests, dancing and being with prospective mates, a behaviour that probably evolved to ensure maximum trust between the birds (raising an albatross chick is a massive energetic investment, and a long courting period establishes for both birds that the other is committed). They will start reproducing after about seven years, mating every two years.
Nests are simple depressions scraped in the sand, into which one dull white with reddish brown spots egg is laid. The egg is incubated for just over two months (65 days). Both birds incubate the egg, the male incubating more as the female leaves soon after hatching to recoup reserves used for egg-laying. The average time spent on incubating shifts is 18 days. However, mates can wait up to 38 days to be relieved, and if something happens to the mate the other has been recorded incubating for 49 days without food or water.
The chick is brooded for 20 days by its parents, after which both parents leave the nest and return to feed the chick. The chick is fed regurgitated food by sticking its bill inside that of its parent. Fledging occurs after 140 days.


The black-footed albatross feeds in pelagic waters, taking the eggs of flying fish, squid and to a lesser extent crustaceans. It will also consume floating debris, including plastics.


The black-footed albatross is considered near threatened by the IUCN, because it is taken incidentally by longline fishing. An estimated 4,000 are taken every year, based on the number taken in 1990; other estimates put the number at 8,000, although more recent numbers are at around 6,150 per year with the majority of deaths from Taiwanese and Japanese fishing fleets. It is also vulnerable to oil and ingestion of floating plastics, which reduces the space in the stomach available for food to be brought to the chick. Finally volcanic eruptions on Torishima continues to be a threat.
The black-footed albatross has an occurrence range of 37,600,000 km² (14,500,000 sq mi) and a breeding range of 28 km² (11 sq mi), with a population of 129,000 adult birds. Of these birds 24,000 pairs breed on Midway Atoll and 21,000 pairs breed on Laysan Island. Torishima has 1,218 pairs, the Bonin Islands have 23 pairs and there are about 400 pairs on offshore Mexican islands with 337 on Islas Guadalupe. All of these numbers come from estimates from 2005 to 2007.
All of its nesting sites in the U.S. are protected, along with a 50 nmi (93 km) buffer zone around these islands. Within this buffer zone longline fishing is outlawed. Almost 80% of the breeding population is counted or sampled each year and most fisheries utilize seabird bycatch prevention measures.


Phoebis agarithe, the large orange sulphur, is a butterfly in the  family Pieridae. It is found from Peru north to southern Texas and peninsular Florida. Rare strays can be found up to Colorado, South Dakota, Wisconsin, and New Jersey. The species has also been introduced in Hawaii. The habitat consists of open, tropical lowlands including gardens, pastures, road edges, trails and parks.
The wingspan is 57–86 mm (2.2–3.4 in). The upper surface of the males is bright orange without markings. There are two female forms, a pink-white and yellow-orange form. The underside of the forewings of both sexes has a straight submarginal line. There are two seasonal forms: the winter form has heavier underside markings. Adults are on wing from August to September in southern Texas and all year round in the tropics. They feed on flower nectar, favoring lantana, shepherd's needle, bougainvillea, rose periwinkle, Turk's cap and hibiscus.
The larvae feed on fresh leaves of Pithecellobium and Inga species.


The following subspecies are recognised:
Phoebis agarithe agarithe (Texas, Mexico)
Phoebis agarithe fischeri (H. Edwards, 1883) (Baja California)
Phoebis agarithe maxima (Neumoegen, 1891) (Florida)
Phoebis agarithe antillia Brown, 1929 (Haiti)
Phoebis agarithe pupillata Dillon, 1947 (Dominica)
Phoebis agarithe tumbesina Lamas, 1981 (Peru)


Phoebis philea, the orange-barred sulphur, is a species of butterfly found in the Americas including the Caribbean.
The wingspan is 68 to 80 mm. There are two to three generations per year in Florida and one in the northern part of the range with adults on wing from mid to late summer. The species habitat is in tropical scrub, gardens, fields, and forest edges. Orange-barred sulphurs are often found in large dense groups of mixed species, including the statira sulphur (Aphrissa statira), apricot sulphur (Phoebis argante), and the straight-line sulphur (Rhabdodryas trite). The species eats nectar from red-colored plants.
The larvae feed on Cassia species.


Phoebis sennae, the cloudless sulphur, is a mid-sized butterfly in the family Pieridae found in the Americas. There are several similar species such as the yellow angled-sulphur (Anteos maerula), which has angled wings, statira sulphur (Aphrissa statira), and other sulphurs, which are much smaller.


Their range is wide, from South America to southern Canada, in particular southwestern Ontario.  They are most common from Argentina to southern Texas, Georgia, and Florida, but are often visitors outside this range becoming more rare further north.


The common habitats of this butterfly are open spaces, gardens, glades, seashores, and watercourses.


The adult butterfly feeds on nectar from many different flowers with long tubes including cordia, bougainvillea, cardinal flower, hibiscus, lantana, and wild morning glory. The larvae also feed on sennas and partridge peas.
Senna hebecarpa (American senna) is a larval host and nectar source for the cloudless sulphur butterfly in the Eastern United States.


The breeding season is dependent on the climate of the area, from midsummer to fall in the cooler areas, to year-round where the climate is warmer.


The cloudless sulphur starts off as a pitcher-shaped white egg.  Eventually it will turn to a pale orange.  The egg stage lasts six days.


Once the egg hatches, a caterpillar emerges that is yellow to greenish, striped on sides, with black dots in rows across the back. The host plant may be partridge pea (Chamaecrista cinerea), sennas (Senna), clovers (Trifolium), or other legumes (Fabaceae).  The caterpillar will usually grow to a length between 41 and 45 mm (1.6 and 1.8 in).


The caterpillar will form a chrysalis that is pointed at both ends and humped in the middle. The chrysalis will be either yellow or green with pink or green stripes. From the chrysalis comes a medium-sized butterfly (55–70 mm (2.2–2.8 in)) with fairly elongated but not angled wings.


The male butterfly is clear yellow above and yellow or mottled with reddish brown below and the female is lemon yellow to golden or white on both surfaces, with varying amounts of black spotting along the margin and a black open square or star on the bottom forewing. Wingspan: 63–78 mm (2.5–3.1 in).


The Chilean flamingo (Phoenicopterus chilensis) is a species of large flamingo at 110–130 cm (43–51 in) closely related to the American flamingo and the greater flamingo, with which it was sometimes considered conspecific. The species is listed as near threatened by the IUCN.
It breeds in South America from Ecuador and Peru to Chile and Argentina and east to Brazil; it has been introduced into the Netherlands. Like all flamingos, it lays a single chalky-white egg on a mud mound.
These flamingos are mainly restricted to salt lagoons and soda lakes but these areas are vulnerable to habitat loss and water pollution.


The plumage is pinker than the slightly larger greater flamingo, but less so than the Caribbean flamingo. It can be differentiated from these species by its grayish legs with pink joints (tibiotarsal articulation), and also by the larger amount of black on the bill (more than half). Young chicks may have no sign of pink coloring whatsoever, but instead remain gray or peach.


The Chilean flamingo's bill is equipped with comb-like structures that enable it to filter food—mainly algae and plankton—from the water of the coastal mudflats, estuaries, lagoons, and salt lakes where it lives.


Chilean flamingos live in large flocks in the wild and require crowded conditions to stimulate breeding. During breeding season, males and females display a variety of behaviors to attract mates, including head flagging—swiveling their heads from side-to-side in tandem—and wing salutes, where the wings are repeatedly opened and closed. Flamingos in general have a poor record of successful breeding because they will delay reproduction until the environmental conditions are favorable for breeding.
Males and females co-operate in building a pillar-shaped mud nest, and both incubate the egg laid by the female. Both parents also take turns incubating the egg. Upon hatching, the chicks have gray plumage; they do not gain the typical pink adult coloration for 2–3 years. Both male and female flamingos can produce a nutritious fluid from glands in their crop to feed their young. Due to their diet, this crop milk is crimson in color.


The first flamingo hatched in a European zoo was a Chilean flamingo at Zoo Basel  (Switzerland) in 1958.
In 1988, a Chilean flamingo that lived in the Tracy Aviary in Salt Lake City, Utah, had mistakenly not received his routine wing clipping. The flamingo escaped, and became a local legend in the greater Salt Lake area known as Pink Floyd the Flamingo. Pink Floyd came to Utah in the winters to eat the brine shrimp that live in the Great Salt Lake, and flew north to Idaho and Montana in the spring and summer. Pink Floyd became a popular tourist attraction and local icon until his disappearance and presumed death after he flew north to Idaho one spring in 2005 and was never seen again.
Since there is such a decline in this species, breeding programs have been implemented in zoos to offset the decline of the wild stock numbers.


The greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. It is found in Africa, the Indian subcontinent, the Middle East, and in southern Europe.


The greater flamingo was described by Peter Simon Pallas in 1811. It was previously thought to be the same species as the American flamingo (Phoenicopterus ruber), but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species. The greater flamingo has no subspecies.


The greater flamingo is the largest living species of flamingo, averaging 110–150 cm (43–59 in) tall and weighing 2–4 kg (4.4–8.8 lb). The largest male flamingos have been recorded at up to 187 cm (74 in) tall and 4.5 kg (9.9 lb).
Most of the plumage is pinkish-white, but the wing coverts are red and the primary and secondary flight feathers are black. The bill is pink with a restricted black tip, and the legs are entirely pink. The call is a goose-like honking.
Chicks are covered in gray fluffy down. Subadult flamingos are paler with dark legs. Adults feeding chicks also become paler, but retain the bright pink legs. The coloration comes from the carotenoid pigments in the organisms that live in their feeding grounds.
Secretions of the uropygial gland also contain carotenoids.  During the breeding season, greater flamingos increase the frequency of their spreading uropygial secretions over their feathers and thereby enhance their color.  This cosmetic use of uropygial secretions has been described as applying "make-up".


It is found in parts of Africa, southern Asia (Bangladesh and coastal regions of Pakistan, India, and Sri Lanka), the Middle East  (Bahrain, Cyprus, Iraq,  Iran, Palestine, Kuwait, Lebanon, Qatar, and the United Arab Emirates) and southern Europe (including Albania, Bulgaria, Greece, Italy, Montenegro, North Macedonia, Portugal, Spain, Turkey, and South of France). The most northern breeding spot is the Zwillbrocker Venn in western Germany, close to the border with the Netherlands. They have been recorded breeding in the United Arab Emirates at three different locations in the Abu Dhabi Emirate.
In Gujarat, a state of India, flamingos can be observed at the Nal Sarovar Bird Sanctuary, Khijadiya Bird Sanctuary, Flamingo City, and in the Thol Bird Sanctuary. They remain there during the entire winter season.


The greater flamingo resides in mudflats and shallow coastal lagoons with salt water. Using its feet, the bird stirs up the mud, then sucks water through its bill and filters out small shrimp, seeds, blue-green algae, microscopic organisms, and mollusks. The greater flamingo feeds with its head down, and its upper jaw is movable and not rigidly fixed to its skull.
Like all flamingos, this species lays a single chalky-white egg on a mud mound.


The typical lifespan in captivity, according to Basel Zoo, is over 60 years. In the wild, the average lifespan is 30 – 40 years.


Adult greater flamingos have few natural predators. Eggs and chicks may be eaten by raptors, crows, gulls, and the marabou stork (Leptoptilos crumenifer); an estimated half of the predation of greater flamingo eggs and chicks is from the yellow-legged gull (Larus michahellis).


The first recorded zoo hatch was in 1959 at Zoo Basel. In Zoo Basel's breeding program, over 400 birds have been hatched with between 20 and 27 per year since 2000. The oldest known greater flamingo was a bird at the Adelaide Zoo in Australia that died aged at least 83 years. The bird's exact age is not known; he was already a mature adult when he arrived in Adelaide in 1933. He was euthanized in January 2014 due to complications of old age.


The American flamingo (Phoenicopterus ruber) is a large species of flamingo closely related to the greater flamingo and Chilean flamingo native to the Neotropics. It was formerly considered conspecific with the greater flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists' Unions) as incorrect due to a lack of evidence. It is also known as the Caribbean flamingo, although it is also present in the Galápagos Islands. It is the only flamingo that naturally inhabits North America.


The American flamingo breeds in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago,  Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and Cameron Parish, Louisiana, and extreme southern Florida in the United States). It is a vagrant to Puerto Rico, Anguilla, Barbados, and Honduras. The population in the Galápagos Islands differs genetically from that in the Caribbean; the Galápagos flamingos are significantly smaller, exhibit sexual dimorphism in body shape, and lay smaller eggs. They are sometimes separated as Phoenicopterus ruber glyphorhynchus.
Its preferred habitats are similar to those of its relatives: saline lagoons, mudflats, and shallow, brackish coastal or inland lakes. An example habitat is the Petenes mangroves ecoregion of the Yucatán.


The American flamingo is also found in South Florida and the Florida Keys, both of which were likely the northernmost extent of its distribution. The existence of flamingo eggs in museum collections labeled as collected from Florida indicates that they likely nested there as well. Since the arrival of Europeans, the population started to decline, up until the 1900s, where it was considered completely extirpated. During the 1950s, birds from the captive population at Hialeah Park frequently escaped, thus leading to the conclusion that all modern flamingos in Florida were escapees, although at least one bird banded as a chick in the Yucatán Peninsula has been sighted in Everglades National Park.
However, a study published in 2018, involving an abandoned young flamingo named Conchy found in Key West, indicates that the occasional flamingos observed in parts of Florida are in fact natives, with some even permanently staying in Florida Bay year-round. The study also indicated that these flamingos may be increasing in population and reclaiming their lost range, slowly but steadily returning home.  Large flocks of flamingos are still known to visit Florida from time to time, most notably in 2014, when a very large flock of over 147 flamingos temporarily stayed at Stormwater Treatment Area 2, on Lake Okeechobee, with a few returning the following year. From a distance, untrained eyes can also confuse it with the roseate spoonbill.


The American flamingo is a large wading bird with reddish-pink plumage. Like all flamingos, it lays a single chalky-white egg on a mud mound, between May and August; incubation until hatching takes from 28 to 32 days; both parents brood the young for a period up to 6 years when they reach sexual maturity. Their life expectancy of 40 years is one of the longest in birds.
Adult American flamingos are smaller on average than greater flamingos, but are the largest flamingos in the Americas. They measure from 120 to 145 cm (47 to 57 in) tall. The males weigh an average of 2.8 kg (6.2 lb), while females average 2.2 kg (4.9 lb). Most of its plumage is pink, giving rise to its earlier name of rosy flamingo and differentiating adults from the much paler greater flamingo. The wing coverts are red, and the primary and secondary flight feathers are black. The bill is pink and white with an extensive black tip. The legs are entirely pink. The call is a goose-like honking.
It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds  applies.


Mating and bonding behaviors of P. ruber individuals have been extensively studied in captivity. The American flamingo is usually monogamous when selecting a nest site, and incubating and raising young; however, extra-pair copulations are frequent.
While males usually initiate courtship, females control the process. If interest is mutual, a female walks by the male, and if the male is receptive, he  walks with her. Both parties  make synchronized movements until one member aborts this process. For low-intensity courtships, males and females  walk in unison with their heads raised. In high-intensity courtships, males and females  walk at a quick pace with their heads dropped in a false feeding posture. This high-intensity courtship stops at any point if either bird turns and the other does not follow, the heads are raised, unison movements are stopped, or the pace of movement is slowed. If the female is ultimately receptive to copulation, she stops walking and presents for the male. Long-term pairs do not frequently engage in courtship behaviors or in-group display. Pairs often stand, sleep, and eat in close proximity.
Courtship is most often seen among individuals that change partners often or are promiscuous. A spectrum of pairing relationships is seen. Some birds have a long-term partner throughout the year; others form pairs during periods of courtship and nest attendance. How long a relationship lasts is affected by many factors, including addition and removal of adults, maturation of juveniles, and occurrence of trios and quartets. In most pairs, both individuals usually construct and defend the nest site. In rare cases, one individual undertakes both duties. Within trios, the dominant pair begins the nesting process by choosing and then defending the site.
For trios with one male and two females, the subordinate female is tolerated by the male, but often fights with the dominant female. If two females share a nest and both lay an egg, one female will try to destroy the other egg or roll it out of the nest. For trios with two males and one female, the subordinate male is tolerated by both individuals and  often becomes the primary incubator and caregiver of the chicks. For quartets, the dominant male and two females take care of the nest, while the subordinate male remains around the periphery, never gaining access to the nest. Less animosity is observed between the dominant and subordinate females in quartets compared to trios.
The egg is attended constantly and equally by alternating parents. Chicks at the nest are attended constantly by alternating parents, up to 7–11 days of age. Most attentive periods during incubation and brooding last 21–60 hours, both in the case where the ‘off-duty’ parents remain in the same lagoon to feed, or (when breeding occurs in lagoons deficient in food),  they fly to other lagoons to feed. Nest reliefs during incubation take place predominantly in late afternoon, or early morning.
The time for receiving food from parents decreases from hatching to about 105 days, and the decrease is greatest after the chicks have left the nest at 7–11 days to band into crèches. The frequency and the duration of feeds by male and female partners do not differ significantly. After chicks have left the nest, feeds are predominantly nocturnal.


The American flamingo has adapted to its shallow-water environment in several ways. It has evolved long legs and large webbed feet to wade and stir up the bottom of the water bed to bring up their food source to then be retrieved. To feed, it has evolved a specialized beak which is hooked downward and features marginal lamellae on the upper mandible, and inner and outer lamellae on both the upper and lower mandibles. These are adapted for filtering out differently sized food from water. Depending on the food source in their area, diets depend on the exact morphology of their beaks on what can and cannot be strained out of them. The American flamingos’ diet consists of small crustaceans, molluscs, some worms, nematodes, insects and their larvae, small fish, widgeon grass, seeds and algae. They are also known to consume mud from which they are able to get microorganisms and bacteria and obtain nutrients. It submerges its head under water to retrieve its food, and may have its head under water for long times, which requires it to hold its breath. Factors which affect the habitat choice of American flamingos are environmental temperatures, water depth, food source, accessibility of an area, and the presence of vegetation beds in feeding areas. If available food items do not meet the needs of the flamingos or the temperature is not appropriate to their requirements, they move to a better feeding or more temperate area.


The role of osmoregulation—the maintenance of a precise balance of solute and water concentrations within the body—is performed by a number of bodily functions working together. In P. ruber, the kidney, the lower gastrointestinal tract, and the salt glands work together to maintain the homeostasis between ions and fluids. In mammals, the kidneys and urinary bladder are the primary organs used in osmoregulation. Birds, however, lack a urinary bladder and must compensate using these three organs.
American flamingos are saltwater birds that ingest food with a high salt content and mostly drink salt water (with an osmolarity of usually 1000), hyperosmotic to the bodies cells . Also, though not commonly, they can drink fresh water at near-boiling temperatures from geysers. From their high-salt diet, they would lose more water and have a greater salt uptake. One way in which they osmoregulate is through the use of a salt gland, which is found in their beaks. This salt gland helps excrete excess salt from the body through the nasal openings in the flamingo's beaks. When these birds consume salt, the osmolarity increases in the blood plasma through the gut. This causes water to move out of the cells, increasing extracellular fluids. Both these changes, in turn, activate the salt glands of the bird, but before any activity occurs in the salt glands, the kidney has to reabsorb the ingested sodium from the small intestine. As seen in other saltwater birds, the fluid that is excreted has been seen to have an osmolarity greater than that of the salt water, but this varies with salt consumption and body size.
As food and saltwater are ingested, sodium and water absorption begins through the walls of the gut and into the extracellular fluid. Sodium is then circulated to the kidney, where the plasma undergoes filtration by the renal glomerulus. Although birds' kidneys tend to be larger in size, they are inefficient in producing concentrated urine that is significantly hyperosmotic to their blood plasma. This form of secretion would cause dehydration from water loss. Therefore, sodium and water are reabsorbed into the plasma by renal tubules. This increase in osmotic plasma levels causes extracellular fluid volume to increase, which triggers receptors in both the brain and heart. These receptors then stimulate salt gland secretion and sodium is able to efficiently leave the body through the nares while maintaining a high body water level.
Flamingos, like many other marine birds, have a high saline intake, yet even the glomular filtration rate (GFR) remains unchanged. This is because of the salt glands; high concentrations of sodium are present in the renal filtrate, but can be reabsorbed almost completely where it is excreted in high concentrations in the salt glands. Renal reabsorption can be increased through the output of the antidiuretic hormone called arginine vasotacin (AVT). AVT opens protein channels in the collection ducts of the kidney called aquaporins. Aquaporins increase the membrane permeability to water, as well as causes less water to move from the blood and into the kidney tubules.


The salt gland used by the American flamingo has two segments, a medial and lateral segment. These segments are tube shaped glands that consist of two cell types. The first is the cuboidal – peripheral cells which are small, triangular shaped cells which have only a few mitochondria. The second specialized cells are the principal cells which are found down the length of the secretory tubules, and are rich in mitochondria. These cells are similar to the mitochondria rich cells found in teleost fish.
These cells within the salt gland employ several types of transport mechanisms that respond to osmoregulatory loads. Sodium-Potassium ATPase works with a Sodium-Chloride cotransporter (also known as the NKCC), and a basal potassium channel to secrete salt (NaCl) into secretory tubes. The ATPase uses energy from ATP to pump three sodium ions out of the cell and two potassium ions into the cell. The potassium channel allows potassium ions to diffuse out of the cell. The cotransporter pumps one sodium, potassium and two chloride ions into the cell. The chloride ion diffuses through the apical membrane into the secretory tube and the sodium follows via a paracellular route. This is what forms the hyperosmotic solution within the salt glands.


Similar to the atrium, the arteries are composed of thick elastic muscles to withstand the pressure of the ventricular constriction, and become more rigid as they move away from the heart. Blood moves through the arteries, which undergo vasoconstriction, and into arterioles which act as a transportation system to distribute primarily oxygen as well as nutrients to all tissues of the body. As the arterioles move away from the heart and into individual organs and tissues they are further divided to increase surface area and slow blood flow. Travelling through the arterioles blood moves into the capillaries where gas exchange can occur. Capillaries are organized into capillary beds in tissues, it is here that blood exchanges oxygen for carbon dioxide waste. In the capillary beds blood flow is slowed to allow maximum diffusion of oxygen into the tissues. Once the blood has become deoxygenated it travels through venules then veins and back to the heart. Veins, unlike arteries, are thin and rigid as they do not need to withstand extreme pressure. As blood travels through the venules to the veins a funneling occurs called vasodilation bringing blood back to the heart. Once the blood reaches the heart it moves first into the right atrium, then the left ventricle to be pumped through the lungs for further gas exchange of carbon dioxide waste for oxygen. Oxygenated blood then flows from the lungs through the left atrium to the left ventricle where it is pumped out to the body. With respect to thermoregulation, the American flamingo has highly vascularized feet that use a countercurrent exchange system in their legs and feet. This method of thermoregulation keeps a constant gradient between the veins and arteries that are in close proximity in order to maintain heat within the core and minimize heat loss or gain in the extremities. Heat loss is minimized while wading in cold water, while heat gain is minimized in the hot temperatures during rest and flight.


Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight. Birds, like the flamingo, have a very efficient system for diffusing oxygen into the blood; birds have a ten times greater surface area to gas exchange volume than mammals. As a result, birds have more blood in their capillaries per unit of volume of lung than a mammal. The American flamingo's four-chambered heart is myogenic, meaning that all the muscle cells and fibers have the ability to contract rhythmically. The rhythm of contraction is controlled by the pace maker cells which have a lower threshold for depolarization. The wave of electrical depolarization initiated here is what physically starts the heart's contractions and begins pumping blood. Pumping blood creates variations in blood pressure and as a result, creates different thicknesses of blood vessels. The Law of LaPlace can be used to explain why arteries are relatively thick and veins are thin.


It was widely thought that avian blood had special properties which attributed to a very efficient extraction and transportation of oxygen in comparison to mammalian blood. This is not true; there is no real difference in the efficiency of the blood, and both mammals and birds use a hemoglobin molecule as the primary oxygen carrier with little to no difference in oxygen carrying capacity. Captivity and age have been seen to have an effect on the blood composition of the American flamingo. A decrease in white blood cell numbers was predominate with age in both captive and free living flamingos, but captive flamingos showed a higher white blood cell count than free living flamingos. One exception occurs in free living flamingos with regards to white blood cell count. The number of eosinophils in free living birds are higher because these cells are the ones that fight off parasites with which a free living bird may have more contact than a captive one. Captive birds showed higher hematocrit and red blood cell numbers than the free living flamingos, and a blood hemoglobin increase was seen with age. An increase in hemoglobin would correspond with an adults increase in metabolic needs. A smaller mean cellular volume recorded in free living flamingos coupled with similar mean hemoglobin content between captive and free living flamingos could show different oxygen diffusion characteristics between these two groups. Plasma chemistry remains relatively stable with age but lower values of protein content, uric acid, cholesterol, triglycerides, and phospholipids were seen in free living flamingos. This trend can be attributed to shortages and variances in food intake in free living flamingos.


Thermoregulation is a matter of keeping a consistent body temperature regardless of the surrounding ambient temperature. Flamingos require both methods of efficient heat retention and release. Even though the American flamingo resides mainly close to the equator where there is relatively little fluctuation in temperature, seasonal and circadian variations in temperature must be accounted for.
Like all animals, flamingos maintain a relatively constant basal metabolic rate (BMR); the metabolic rate of an animal in its thermoneutral zone (TNZ) while at rest. The BMR is a static rate which changes depending on factors such as the time of day or seasonal activity. Like most other birds, basic physiological adaptations control both heat loss in warm conditions and heat retention in cooler conditions. Using a system of countercurrent blood flow, heat is efficiently recycled through the body rather than being lost through extremities such as the legs and feet.
Living in the equatorial region of the world, the American flamingo has little variation in seasonal temperature changes. However, as a homeothermic endotherm it is still faced with the challenge of maintaining a constant body temperature while being exposed to both the day (light period) and night (dark period) temperatures of its environments. Phoenicopterus ruber have evolved a number of thermoregulatory mechanisms to keep itself cool during the light period and warm during the dark period without expending too much energy. The American flamingo has been observed in a temperature niche between 17.8–35.2 °C (64.0–95.4 °F). In order to prevent water loss through evaporation when temperatures are elevated the flamingo will employ hyperthermia as a nonevaporative heat loss method keeping its body temperature between 40–42 °C (104–108 °F). This allows heat to leave the body by moving from an area of high body temperature to an area of a lower ambient temperature. Flamingos are also able to use evaporative heat loss methods such as, cutaneous evaporative heat loss and respiratory evaporative heat loss. During cutaneous heat loss, Phoenicopterus ruber relies on evaporation off of the skin to reduce its body temperature. This method is not very efficient as it requires evaporation to pass through the plumage. A more efficient way to reduce its body temperature is through respiratory evaporative heat loss, where the flamingo engages in panting to expel excessive body heat. During the dark period the flamingos tend to tuck their heads beneath their wing to conserve body heat. They may also elicit shivering as a means of muscular energy consumption to produce heat as needed.
One of the most distinctive attribute of P. ruber is its unipedal stance, or the tendency to stand on one leg. While the purpose of this iconic posture remains ultimately unanswered, strong evidence supports its function in regulating body temperature. Like most birds, the largest amount of heat is lost through the legs and feet; having long legs can be a major disadvantage when temperatures fall and heat retention is most important. By holding one leg up against the ventral surface of the body, the flamingo lowers the surface area by which heat exits the body. Moreover, it has been observed that during periods of increased temperatures such as mid-day, flamingos will stand on both legs. Holding a bipedal stance multiplies the amount of heat lost from the legs and further regulates body temperature.


Like other flamingo species, American flamingos will migrate short distances to ensure that they get enough food or because their current habitat has been disturbed in some way. One habitat disturbance that has been observed to cause flamingos to leave their feeding grounds is elevated water levels. These conditions make it difficult for Phoenicopterus ruber to wade, hindering their ability to access food. The flamingos will then abandon their feeding grounds in search of an alternate food source. While the flights are not as long as other migratory birds, flamingos still fly for periods without eating.


The species' metabolism resembles that of other salt water wading birds. They will fast when migrating to a new habitat or the chicks may not receive food daily depending on food availability.


The green wood hoopoe (Phoeniculus purpureus) is a large, up to 44 cm (17 in) long, near-passerine tropical bird native to Africa. It is a member of the family Phoeniculidae, the wood hoopoes, and was formerly known as the red-billed wood hoopoe.


This abundant species is a metallic dark green, with a purple back and very long diamond-shaped purple tail. Distinctive white markings on the wings and white chevrons on the tail edges make it easily identifiable, as does its long, thin, curved red bill. Sexes are similar, but immatures have a black bill.


The green wood hoopoe is an insect-eating species. It feeds mainly on the ground, termite mounds, or on tree trunks, and forms flocks outside the breeding season. Its specialised claws enable it to cling easily to the underside of branches while closely inspecting the bark for insects.


This conspicuous bird advertises its presence with its loud kuk-uk-uk-uk-uk call and other vocalisations.


The green wood hoopoe is a cooperative breeder and common resident in the forests, woodlands and suburban gardens of most of sub-Saharan Africa. It is found in groups of up to a dozen or so birds with only one breeding pair. The breeding female lays two to four blue eggs in a natural tree hole or old barbet nest and incubates them for about 18 days. On hatching, she and the nestlings are fed by the rest of the group, even after they have fledged and left the nest hole. The group is fearless in defence of the nestlings against intruders. This species is parasitised by the greater and lesser honeyguide.


Widespread and common throughout its large range, the green wood hoopoe is assessed as Least Concern on the IUCN Red List of Threatened Species.


The plumbeous water redstart (Phoenicurus fuliginosus) is a passerine bird in the Old World flycatcher family Muscicapidae. It is found in South Asia, Southeast Asia and China.  Males are slate blue in colour, while females are grey.  The bird's common name refers to its colour which resembles lead.  They tend to live near fast-moving streams and rivers.


The plumbeous water redstart belongs to the order Passeriformes and the family Muscicapidae.  It was previously placed in the genus Rhyacornis but was moved to Phoenicurus based on the results of a molecular phylogenetic study published in 2010. The species consists of two recognized subspecies – Phoenicurus fuliginosus fuliginosus and Phoenicurus fuliginosus affinis.  The former was described by Nicholas Aylward Vigors in 1831, while the latter was described by William Robert Ogilvie-Grant in 1906 and is found in Taiwan.  In China, the female and first-year male redstarts appear more brown at the top, leading to the possibility of classifying them as a separate race tenuirostris.


The plumbeous water redstart is typically 14 centimetres (5.5 in) long in total, with an average weight of 22 grams (0.78 oz) for males and 18.8 grams (0.66 oz) for females.  The male birds are slate blue in colour with a tail that is rusty red.  On the other hand, female birds are pale grey and feature a white rump.


The bird is found in Afghanistan, Bangladesh, Bhutan, China, India, Laos, Myanmar, Nepal, Pakistan, Taiwan, Thailand, and Vietnam.  Their preferred habitats are streams, nullahs and rivers with boulders that are shaded, as well as vegetation near riverbanks.  Streams with higher populations of insects such as mayflies appear to be preferred.
They are typically found at relatively high elevations, with the ones living in the Himalayas seen between 2,000 metres (6,600 ft) and 4,100 metres (13,500 ft).  However, they tend to descend to lower altitudes during the winter.
The plumbeous water redstart has been placed on the Least Concern category of the IUCN Red List, as the population has remained stable throughout the last ten years.  The size of its distribution range is over 5,100,000 square kilometres (2,000,000 sq mi).


The plumbeous water redstart is very protective of its habitat and will be extremely confrontational to any trespasser on its territory.  In order to catch flies in rivers, it flies vertically until it is at least 20 feet (6.1 m) above the water, before gliding down in a spiral back to the same place.


The black redstart (Phoenicurus ochruros) is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae). Obsolete common names include Tithys redstart, blackstart (not to be confused with the species currently known as blackstart) and black redtail.


The first formal description of the black redstart was by the German naturalist Samuel Gottlieb Gmelin in 1774 under the binomial name Mottacilla ochruros. The genus Phoenicurus was introduced by the English naturalist Thomas Forster in 1817. Both parts of the scientific name are from Ancient Greek and refer to the colour of the tail. The genus name Phoenicurus is from phoinix, "red", and -ouros -"tailed", and the specific ochruros is from okhros, "pale yellow" and -ouros.
The black redstart is a member of a temperate Eurasian clade which also includes the Daurian redstart, Hodgson's redstart, the white-winged redstart, and maybe Przevalski's redstart. The present species' ancestors diverged from about 3 million years ago (mya) (Late Pliocene) onwards and spread throughout much of Palearctic from 1.5 mya onward. It is not very closely related to the common redstart. As these are separated by different behaviour and ecological requirements and have not evolved fertilisation barriers, the two European species can nonetheless produce apparently fertile and viable hybrids.
There are a number of subspecies which differ mainly in underpart colours of the adult males; different authorities accept between five and seven subspecies. They can be separated into three major groups, according to morphology, biogeography, and mtDNA cytochrome b sequence data.
P. o. phoenicuroides group. Basal central and eastern Asian forms which diverged from the ancestral stock as the species slowly spread west (c. 3–1.5 mya). Females and juveniles light grey brown.
Phoenicurus ochruros phoenicuroides. Tian Shan eastwards to Mongolia. Small; adult males have lower breast, belly and flanks deep rufous, pale wing-patch absent, sometimes white forehead. Overall quite similar to a much darker common redstart with black chest. Females and juveniles are similar to common redstart but have an overall sandier, paler colour and often a distinct buff eye-ring.
Phoenicurus ochruros murinus. Altai, Tuva, northern China and western Mongolia. Distinguished from the previous Turkestan subspecies by the absence of any contrast in the colour of the head, nape and back, all of which are concolorous dark grey.
Phoenicurus ochruros rufiventris. Turkmenistan eastwards through Pamir and Alay Mountains to Himalaya. Usually large; adult males like P. o. phoenicuroides, but darker overall, with black back and rufous-chestnut underside. Females with rufous tinge to underside. Exact limits with P. o. phoenicuroides unresolved.
Phoenicurus ochruros xerophilus. China east of and between ranges of preceding two. Large; colour pattern like P. o. phoenicuroides but paler. Included in P. o. rufiventris by many authorities.
P. o. ochruros group. Western Asian forms, whose lineage separated from the gibraltariensis group c. 1.5–0.5 mya. Females and juveniles intermediate.
Phoenicurus ochruros ochruros. Eastern Turkey, Alborz, and Caucasus. Small, somewhat intermediate between P. o. phoenicuroides and P. o. gibraltariensis. Generally like latter, but rufous underside, pale wing patch weakly developed.
Phoenicurus ochruros semirufus. Levant. Small; adult males somewhat similar to rufiventris except in size. Black areas extensive.
P. o. gibraltariensis group. European population, which formed as a distinct subspecies probably during the last ice age. Females and juveniles dark grey.
Phoenicurus ochruros gibraltariensis. Western Europe east to the Crimea and western Turkey. Neck, upper back and shoulders dark slate grey to black in adult males, lighter than face and neck, pale wing patch strongly developed.
Phoenicurus ochruros aterrimus. Iberia and Morocco. Neck, upper back and shoulders black in adult males. Wide intergradation with P. o. gibraltariensis and treated as a synonym of it by many authorities.


The black redstart is 13–14.5 cm (5.1–5.7 in) in length and 12–20 g (0.42–0.71 oz) in weight, similar to the common redstart. The adult male is overall dark grey to black on the upperparts and with a black breast; the lower rump and tail are orange-red, with the two central tail feathers dark red-brown. The belly and undertail are either blackish-grey (western subspecies; see Taxonomy and systematics, above) or orange-red (eastern subspecies); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel (western subspecies) or all blackish (eastern subspecies). The female is grey (western subspecies) to grey-brown (eastern subspecies) overall except for the orange-red lower rump and tail, greyer than the common redstart; at any age the grey axillaries and underwing coverts are also distinctive (in the common redstart these are buff to orange-red). Yearling males are similar to females but blacker; the whitish wing panel of the western subspecies does not develop until the second year.


It is a widespread breeder in south and central Europe and Asia and north-west Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. It is resident in the milder parts of its range, but north-eastern birds migrate to winter in southern and western Europe and Asia, and north Africa. It nests in crevices or holes in buildings.
In Britain, it is most common as a passage and winter visitor, with only 20–50 pairs breeding. On passage it is fairly common on the east and south coasts, and in winter on the coasts of Wales and western and southern England, with a few also at inland sites. Migrant black redstarts arrive in Britain in October or November and either move on or remain to winter, returning eastward in March or April. They also winter on the south and east coasts of Ireland.
The species originally inhabited stony ground in mountains, particularly cliffs, but since about 1900 has expanded to include similar urban habitats including bombed areas during and after World War II, and large industrial complexes that have the bare areas and cliff-like buildings it favours; in Great Britain, most of the small breeding population nests in such industrial areas. It will catch passing insects in flight, and migrants often hunt in coastal tide-wrack for flies or tiny crustaceans. Its quick ducks of head and body are robin-like, and its tail is often flicked. The male has a rattling song and a tick call.
Eastern race birds are very rare vagrants in western Europe.


The black redstart is socially monogamous. A male pairs with a female to rear young, guards her against other males, and mates with other females.


Phoenix canariensis (the Canary Island date palm or pineapple palm) is a species of flowering plant in the palm family Arecaceae, native to the Canary Islands off the coast of Morocco. It is a relative of Phoenix dactylifera, the true date palm. It is the natural symbol of the Canary Islands, together with the canary Serinus canaria.  Mature P. canariensis are often used in ornamental landscaping and are collected and transplanted to their new planting location.  A Canary Island date palm with 10 m (30 ft) of trunk is approximately 60 years of age.


Phoenix canariensis is a large solitary palm, 10–20 m (33–66 ft) tall, occasionally growing to 40 m (131 ft). The leaves, typically around 75 to 125 in number (but the record is for a tree on the French Riviera which bore 443 green, fresh leaves a one time), , are pinnate, 4–6 m (13–20 ft) long, with 80–100 leaflets on each side of the central rachis. The fruit is an oval, yellow to orange drupe 2 cm (0.79 in) long and 1 cm (0.39 in) in diameter and containing a single large seed; the fruit pulp is edible but not the best of dates.


Common names in English include Canary Island date palm and pineapple palm. The common name in Spanish-speaking countries and in the Canary Islands is palmera canaria.


The Canary Island date palm is typically cultivated in wet-winter or Mediterranean climates,  but also in wet-summer or humid subtropical climates like eastern Australia and the southeastern United States. There are even several instances of cultivated Canary Island date palms in high-latitude oceanic climates, such as Ireland, the UK, and the Channel Islands. It can be cultivated where temperatures rarely fall below −10 or −12 °C (14 or 10 °F) for extended periods, although it will require some protection if cold periods are longer than normal. It is a slowly growing tree, exclusively propagated by seed.
The palm is easily recognized through its crown of leaves and trunk characteristics. It is not uncommon to see Canary Island date palms pruned and trimmed to enhance the appearance. When pruned, the bottom of the crown, also called the nut, appears to have a pineapple shape.
The Canary Island date palm is susceptible to Fusarium wilt, a fungal disease commonly transmitted through contaminated seed, soil, and pruning tools. Spread of the disease can be reduced when pruning tools are disinfected before use on this palm. The South American palm weevil causes them to droop, turn brown and die.
It has gained the Royal Horticultural Society's Award of Garden Merit.


In the Canary Islands, the sap of this date palm is used to make palm syrup. La Gomera is the only island where the syrup is produced in the Canary Islands.


In some areas, Phoenix canariensis has proven to be an invasive plant. In Bermuda and the United States (Florida and California) it is considered naturalised (lives wild in a region where it is not indigenous). It has also spread in some areas of peninsular Spain, Portugal, Italy, Australia, and New Zealand. It is listed as invasive (naturalized) in coastal southern California. In Auckland, New Zealand, the palm has itself become a host for the naturalised Australian strangler fig, Ficus macrophylla.


Phoenix dactylifera, commonly known as date or date palm, is a flowering plant species in the palm family, Arecaceae, cultivated for its edible sweet fruit called dates. The species is widely cultivated across northern Africa, the Middle East, and South Asia, and is naturalized in many tropical and subtropical regions worldwide. P. dactylifera is the type species of genus Phoenix, which contains 12–19 species of wild date palms.
Date trees reach up to 30 metres (100 feet) in height, growing singly or forming a clump with several stems from a single root system. Slow-growing, they can reach over 100 years of age when maintained properly.  Date fruits (dates) are oval-cylindrical, 3 to 7 centimetres (1 to 3 inches) long, and about 2.5 cm (1 in) in diameter, with colour ranging from dark brown to bright red or yellow, depending on variety. Containing 61–68 percent sugar by mass when dried, dates are very sweet and are enjoyed as desserts on their own or within confections.
Dates have been cultivated in the Middle East and the Indus Valley for thousands of years. There is archaeological evidence of date cultivation in Arabia from the 6th millennium BCE. The total annual world production of dates amounts to 8.5 million metric tons, countries of the Middle East and North Africa being the largest producers and consumers.


Date trees reach up to 30 metres (100 feet) in height, growing singly or forming a clump with several stems from a single root system. Slow-growing, they can reach over 100 years of age when maintained properly. The roots have pneumatodes. The leaves are 4–6 m (13–20 ft) long, with spines on the petiole, and pinnate, with about 150 leaflets. The leaflets are 30 centimetres (12 inches) long and 2 cm (1 in) wide. The full span of the crown ranges from 6–10 m (20–33 ft).
The date palm is dioecious, having separate male and female plants. They can be easily grown from seed, but only 50% of seedlings will be female and hence fruit-bearing, and dates from seedling plants are often smaller and of poorer quality. Most commercial plantations thus use cuttings of heavily cropping cultivars. Plants grown from cuttings will fruit 2–3 years earlier than seedling plants.
Dates are naturally wind-pollinated, but in both traditional oasis horticulture and in the modern commercial orchards they are entirely pollinated manually. Natural pollination occurs with about an equal number of male and female plants. However, with assistance, one male can pollinate up to 100 females. Since the males are of value only as pollinators, they are usually pruned in favor of fruit-producing female plants. Some growers do not even maintain any male plants, as male flowers become available at local markets at pollination time. Manual pollination is done by skilled labourers on ladders, or by use of a wind machine. In some areas such as Iraq the pollinator climbs the tree using a special climbing tool that wraps around the tree trunk and the climber's back (called تبلية in Arabic) to keep him attached to the trunk while climbing.
Date fruits are oval-cylindrical, 3–7 cm (1–3 in) long, and 2–3 cm (3⁄4–1+1⁄4 in) diameter, and when ripe, range from bright red to bright yellow in colour, depending on variety. Dates contain a single stone about 2–2.5 cm (3⁄4–1 in) long and 6–8 mm (1⁄4–5⁄16 in) thick. Three main cultivar groups exist: soft (e.g. 'Barhee', 'Halawy', 'Khadrawy', 'Medjool'); semi-dry (e.g. 'Dayri', 'Deglet Nour', 'Zahdi'), and dry (e.g. 'Thoory').


In 2009, a team of researchers at the Weill Cornell Medical College in Qatar published a draft version of the date palm genome (Khalas variety). The draft genome sequence was improved in 2019 with the release of a more complete genome sequence using small molecule real-time sequencing technology by a team from the New York University Abu Dhabi Center for Genomics and Systems Biology and the UAE University Khalifa Center for Genetic Engineering and Biotechnology in the United Arab Emirates. With the release of this improved genome assembly, the UAE researchers were able to map genes for fruit color and sugar content. The NYU Abu Dhabi researchers had also re-sequenced the genomes of several date varieties to develop the first single nucleotide polymorphism map of the date palm genome in 2015.


The species name dactylifera 'date-bearing' is Latin, and is formed with the loanword dactylus in Latin from Greek daktylos (δάκτυλος), which means 'date' (also 'finger'), and with the native Latin fero, which means 'to bear'. The fruit is known as a date. The fruit's English name (through Old French, through Latin) comes from the Greek word for 'finger', δάκτυλος, because of the fruit's elongated shape.


The place of origin of the date palm is uncertain because of long cultivation. According to some sources it probably originated from the Fertile Crescent region straddling Egypt and Mesopotamia while others state that they are native to the Persian Gulf area or even western India. Fossil records show that the date palm has existed for at least 50 million years.


A major palm pest, the red palm beetle (Rhynchophorus ferrugineus), currently poses a significant threat to date production in parts of the Middle East as well as to iconic landscape specimens throughout the Mediterranean world. Pinhas et al. 2008 uses piezoelectric sensors and speech recognition technology to detect R. ferrugineus. They achieved a 98% detection ratio on young P. dactylifera in very controlled laboratory conditions. Another significant insect pest is Ommatissus lybicus, sometimes called the "dubas bug", whose sap sucking results in sooty mould formation.
In the 1920s, eleven healthy Medjool palms were transferred from Morocco to the United States where they were tended by members of the Chemehuevi tribe in a remote region of Nevada. Nine of these survived and in 1935, cultivars were transferred to the "U.S. Date Garden" in Indio, California. Eventually this stock was reintroduced to Africa and led to the U.S. production of dates in Yuma, Arizona, and Bard, California.


Not all cities and countries have benefited with the date palms resilience and ease of growth. It has made the invasive species list in some parts of the United States, Canada and Australia but these references are to the related but inedible Canary Island date palm (Phoenix canariensis).


Dates are a traditional crop throughout the Middle East and north Africa. Dates (especially Medjool and Deglet Nour) are also cultivated in the southwestern United States, and in Sonora and Baja California in Mexico.
Date palms can take 4 to 8 years after planting before they will bear fruit, and start producing viable yields for commercial harvest between 7 and 10 years. Mature date palms can produce 70–140 kilograms (150–300 pounds) of dates per harvest season. They do not all ripen at the same time so several harvests are required. To obtain fruit of marketable quality, the bunches of dates must be thinned and bagged or covered before ripening so that the remaining fruits grow larger and are protected from weather and animals, such as birds, that also like to eat them.
Date palms require well-drained deep sandy loam soils with a pH of 8–11 (alkaline). The soil should have the ability to hold moisture and also be free of calcium carbonate.
Dates have been cultivated in the Middle East and the Indus Valley for thousands of years, and there is archaeological evidence of date cultivation in Mehrgarh, a Neolithic civilization in western Pakistan, around 7000 BCE and in eastern Arabia between 5530 and 5320 calBC. Dates have been cultivated since ancient times from Mesopotamia to prehistoric Egypt. The ancient Egyptians used the fruits to make date wine and ate dates at harvest. Evidence of cultivation is continually found throughout later civilizations in the Indus Valley, including the Harappan period from 2600 to 1900 BCE.
One cultivar, the Judean date palm, is renowned for its long-lived orthodox seed, which successfully sprouted after accidental storage for 2,000 years. The upper survival time limit of properly stored seeds remains unknown. A genomic study from New York University Abu Dhabi Center for Genomics and Systems Biology showed that domesticated date palm varieties from North Africa, including well-known varieties such as Medjool and Deglet Nour, are a hybrid between Middle East date palms and the Cretan wild palm, P. theophrasti. Date palms appear in the archaeological record in North Africa about 2,800 years ago, suggesting that the hybrid was spread by the Minoans or Phoenicians.
An article on date palm tree cultivation is contained in Ibn al-'Awwam's 12th-century agricultural work, Book on Agriculture.


Date seeds are soaked and ground up for animal feed. Their oil is suitable for use in cosmetics and dermatological applications. The oil contains lauric acid (36%) and oleic acid (41%). Date palm seeds contain 0.56–5.4% lauric acid. They can also be processed chemically as a source of oxalic acid. Date seeds are also ground and used in the manner of coffee beans, or as an additive to coffee. Experimental studies have shown that feeding mice with the aqueous extract of date pits exhibit anti-genotoxic effects and reduce DNA damage induced by N-nitroso-N-methylurea.


Stripped fruit clusters are used as brooms. Recently, the floral stalks have been found to be of ornamental value in households.


Apart from P. dactylifera, wild date palms such as Phoenix sylvestris and Phoenix reclinata, depending on the region, can be also tapped for sap.


In North Africa, date palm leaves are commonly used for making huts. Mature leaves are also made into mats, screens, baskets, and fans. Processed leaves can be used for insulating board. Dried leaf petioles are a source of cellulose pulp, used for walking sticks, brooms, fishing floats, and fuel. Leaf sheaths are prized for their scent, and fibre from them is also used for rope, coarse cloth, and large hats.
Young date leaves are cooked and eaten as a vegetable, as is the terminal bud or heart, though its removal kills the palm. The finely ground seeds are mixed with flour to make bread in times of scarcity. The flowers of the date palm are also edible. Traditionally the female flowers are the most available for sale and weigh 300–400 grams (10+1⁄2–14 oz). The flower buds are used in salad or ground with dried fish to make a condiment for bread.


In Ancient Rome the palm fronds used in triumphal processions to symbolize victory were most likely those of P. dactylifera. The date palm was a popular garden plant in Roman peristyle gardens, though it would not bear fruit in the more temperate climate of Italy. It is recognizable in frescoes from Pompeii and elsewhere in Italy, including a garden scene from the House of the Wedding of Alexander. In later times, traders spread dates around southwest Asia, northern Africa, and Spain. Dates were introduced into California by the Spaniards by 1769, existing by then around Mission San Diego de Alcalá, and were introduced to Mexico as early as the 16th century.
Dates are mentioned more than 50 times in the Bible and 20 times in the Quran. Date palms holds great significance in Abrahamic religions. The tree was heavily cultivated as a food source in ancient Israel where Judaism and subsequently Christianity developed. Date palm leaves are used for Palm Sunday in the Christian religion.
Many Jewish scholars believe that the "honey" reference in Exodus chapter 3 to "a land flowing with milk and honey" is actually a reference to date "honey", and not honey from bees. In the Torah, palm trees are referenced as symbols of prosperity and triumph. Psalm 92:12 states that "The righteous shall flourish like the palm tree." Palm branches occurred as iconography in sculpture ornamenting the Second Jewish Temple in Jerusalem, on Jewish coins, and in the sculpture of synagogues. They are also used as ornamentation in the Feast of the Tabernacles. Date palms are one of the seven species of native Israeli plants revered in Judaism. The date palm has historically been considered a symbol of Judea and the Jewish people. The leaves are used as a lulav in the Jewish holiday of Sukkot. They are also commonly used as the s'chach in the construction of a sukkah.
In the Quran, Allah instructs Maryām (the Virgin Mary) to eat dates during labour pains when she gives birth to Isa (Jesus). In Islamic culture, dates and yogurt or milk are traditionally the first foods consumed for Iftar after the sun has set during Ramadan.


Phoenix reclinata (reclinata - Latin, reclining),  the wild date palm or Senegal date palm, is a species of flowering plant in the palm family native to tropical Africa, the Arabian Peninsula, Madagascar and the Comoro Islands. It is also reportedly naturalized in Florida, Puerto Rico, Bermuda and the Leeward Islands. The plants are found from sea level to 3000 m, in rain forest clearings, monsoonal forests and rocky mountainsides.


Phoenix reclinata is a dioecious clumping palm, producing multiple stems from 7.5 to 15 m in height and 30 cm in width. Foliage is pinnate and recurved, growing 2.5 to 4.5 m in length and 0.75 m in width. Leaf color is bright to deep green on 30 cm petioles with long, sharp spines at the base, with 20 to 40 leaves per crown.
The plants are unisexual and florets appear at the top of the palm stem. Male florets are a dirty, pale yellow and fall off after blooming; females are small, globose and yellow-green. This species grows edible, oblong fruit, orange in color (when ripe), at 2.5 cm in diameter. The fruit are borne in large, pendant clusters and contain one seed each.
Palms across the genus Phoenix readily hybridize with one another resulting in naturally occurring variations.  They usually tolerate salt-spray, and moderate drought where the water table is permanently high.


In addition to the fruit, which attracts animals, including humans, the palm heart can be eaten as a vegetable. In KwaZulu-Natal, and the Okavango Delta, Botswana, the sap is tapped shortly before flowering to make palm wine. The fibres of young, unopened leaves can be used to make carpets, kilts and brooms. The roots contain tannin and can be used to make a brown dye. They also produce an edible gum. The wood is lightweight and not particularly useful.


The dark bush-cricket (Pholidoptera griseoaptera) is a flightless species of European bush-cricket; it is the type species of its genus with no subspecies.


Pholidoptera griseoaptera can reach a body length of 11 to 21 mm (males) and 15 to 20 mm (females), much smaller than the similar Pholidoptera aptera. The sickle-shaped and upward curved ovipositor of the females is 8 to 10 mm long, while the males have two short cerci. The antennae and the hind legs are quite long.
The rounded brachypterous wings of the males are brown with light brown to ochre-coloured edges and are about 5 mm in length (about as long as the pronotum). The females are almost wingless or have half-round, grey-brown fore-wings that are 1-2 mm long. Long-winged (macropterous) forms are not recorded.


The dark bush-cricket colonizes a variety of habitats, but avoids sandy soils and are accordingly rare in sandy areas. It is mainly present in forest edges or clearings, but can be found also in wasteland, parks and gardens, at an elevation of about 0–2,100 metres (0–6,890 ft) above sea level.
The females lay their eggs in the soil, in dead branches, in bark crevices and rotting wood. The eggs need high humidity. The larvae require two years for their full development, with seven larval stages. They feed exclusively on vegetables. Nymphs appear at the end of April of the third year, while the first adults appear in June.


Pholisora catullus, the common sootywing or roadside rambler, is a butterfly of the  family Hesperiidae. It is found from the central parts of the United States, south to central Mexico. Strays may colonize up to southern British Columbia, northern Michigan, southern Quebec and southern Maine. It is not found on peninsular Florida.
The wingspan is 25–33 mm. There are two generations with adults on wing from May to August in the northern part of its range and from March to November in Texas.
The larvae feed on Chenopodium album, Amaranthus and Celosia species. Adults feed on flower nectar from various flowers, including dogbane, marjoram, oxalis, white clover, common milkweed, peppermint, cucumber and melon.


Pholistoma auritum is a species of flowering plant in the borage family which is known by the common name blue fiestaflower.


It is native to California, southern Nevada, and Arizona, where it can be found in many types of habitat, from mountain talus to coastal bluffs to desert scrub.


Pholistoma auritum is an annual herb with a brittle, fleshy, bristly stem branching profusely, sometimes forming a tangle. The leaves are deeply lobed and toothed and borne on winged petioles. The foliage is coated in hairs and bristles. The inflorescence is made up of one or more widely bell-shaped flowers up to 1.5 centimeters long and 3 wide. The hair-lined flowers are blue to purple with darker markings in the centers.
The purple Arizona fiestaflower, Pholistoma auritum var. arizonicum, is considered a subspecies.


Pholistoma membranaceum is a species of flowering plant in the borage family which is known by the common name white fiesta flower.
It is native to western North America from central California to Baja California. It can be found in many types of habitat from mountain ravines to beaches to desert scrub generally below 4,500 feet (1,400 m) elevation.


Pholistoma membranaceum is an annual herb with a waxy, fleshy, bristly stem up to 90 centimeters long and branching profusely, sometimes forming a tangle. The leaves are deeply lobed or cut and borne on winged petioles. The foliage is coated in hairs.
The inflorescence consists of cymes of 2 to 10 flowers each under a centimeter wide. Each pedicel is 5–20 millimetres (0.2–0.8 in). Calyx lobes are oblong and 1–3 millimetres (0.04–0.12 in). The flower is white, usually with a purple spot or streak on each of its five lobes.


Pholodes sinistraria, the sinister moth or frilled bark moth, is a moth of the family Geometridae. The species was first described by Achille Guenée in 1857. It is found in the eastern parts of Australia.
The wingspan is about 50 mm for males and 60 mm for females.
The larvae feed on a wide range of plants, including Rosa odorata, Camellia japonica, Persea americana, Citrus unshiu, Cassia species, Ricinus communis, Acacia species and Acmena smithii. Furthermore, it is considered a pest on Macadamia integrifolia.


Phoradendron leucarpum is used in North America as a surrogate for the similar European mistletoe Viscum album, in Christmas decoration and associated traditions (such as "kissing under the mistletoe"), as well as in rituals by modern druids.  It is commercially harvested and sold for those purposes.
Phoradendron leucarpum is the state floral emblem for the state of Oklahoma. The state did not have an official flower, leaving mistletoe as the assumed state flower until the Oklahoma Rose was designated as such in 2004.


Over 60 species of trees are hosts to P. leucarpum, especially trees in the genera of Acer (maple), Fraxinus (ash), Juglans (walnuts), Nyssa, Platanus (plane trees), Populus (poplars), Quercus (oaks), Salix (willows), and Ulmus (elms).


While the sticky substance covering the fruits is toxic to humans, it is a favorite of some birds.


Phormium colensoi (syn. Phormium cookianum – but see below), also called mountain flax, or wharariki in Māori, is a perennial plant that is endemic to New Zealand. The greenish, yellow or orange flowers are followed by twisted seed pods. It is less common than the other Phormium species, P. tenax or harakeke. Mountain flax is also called whararipi, whatariki, mangaeka, kōrari tuauru (Williams 1971), wauraki (Bell 1890 sic.), coastal flax, hill flax and lesser New Zealand flax.


The leaves are under 2 metres in length while those of P. tenax range from 1 to 3 metres in length. The scape is much shorter than that of P. tenax, rising up to 2 metres in height while that of P. tenax is around 5 metres in height. The colour of the inner tepals is green while the outer tepals are yellow to red. In contrast the tepals of P. tenax are a dull red, with the tips of the inner tepals being less strongly recurved. The capsules of P. colensoi, unlike those of P. tenax are twisted and pendulous, and may be twice as long (up to 20 cm in length).
Phormium colensoi has two distinct geographic forms, one occurring in lowland parts of the North Island, and the other in the southern and mountainous areas of the South Island as well as ranges in the North Island. The lowland form has green or yellow tepals and the mountain form has red tepals. In the Cook Strait area, both forms and intermediates can be found.
