Big bluestem is a perennial warm-season bunchgrass. It is tolerant of a wide range of soil conditions. The main roots are 6–10 ft (1.8–3.0 m) deep, and the plants send out strong, tough rhizomes, so it forms very strong sod. Depending on soil and moisture conditions, it grows to a height of 1–3 m (3.3–9.8 ft). The stem base turns blue or purple as it matures.
Big bluestem blooms in the summer and seeds into the fall. The inflorescence (cluster of flowers) is a raceme of two to six, most commonly three, narrow spike-like racemes alternately arranged along the top of the stem. It somewhat resembles a wild turkey's foot. Each raceme contains pairs of spikelets. Each pair has a stalked spikelet with another stalkless spikelet at the base of the stalk. The stalkless spikelet usually has a fertile, perfect floret (with both female and male parts) and an awn (bristle), and the stalked spikelet is awnless, and is sterile or has a staminate (male) flower.


Big bluestem is a midsuccessional grass in prairie and other grassland ecosystems. It grows in tall, dense stands that can outcompete other plant species. The stands grow until disturbance interrupts their spread. It is shade intolerant and is adapted to fire.
It is a host to larvae of several species of butterflies, including the arogos skipper, byssus skipper, cobweb skipper, common wood nymph, Delaware skipper, and dusted skipper.
The larvae of the leaf beetle Diabrotica cristata feed on the roots and the adults visit the flowers of other species of prairie flowers. Many ants decorate their nests with the seeds, including Formica glacialis, F. montana, and F. subsericea. Several species of ants, such as F. glacialis, F. montana, F. subsericea, Lasius minutus, and L. umbratus build nests around the base of this bunchgrass, forming large soil mounds. In larger mounds, the nest is shared by multiple species of ants, and is "likened to an apartment complex with each ant species in its own nest partition". Up to 12 species of ants have been recorded in mounds found in the Chicago region.
The rust fungus Puccinia andropogonis forms black telia on the leaves.


The grass and its variants are good forage for horses and cattle, and can also be cut and used for hay. The grass is high in protein. While not considered the highest quality native forage found in the United States, it has long been considered a desirable and ecologically important grass by cattle ranchers and rangeland ecologists.
Big bluestem is cultivated by specialty plant nurseries for its drought tolerance and native status. It is often grown for wildlife gardens, natural landscaping, and grassland habitat restoration projects.
Due to its high biomass, big bluestem is being considered as a potential feedstock for ethanol production.


Andropogon gerardi is the state grass of Illinois and Missouri and the official prairie grass of Manitoba.


Andropogon ternarius is a species of grass known by the common names split bluestem, splitbeard bluestem, silver bluestem, and paintbrush bluestem. It is native to the southeastern, east-central, and south-central parts of the United States, where it occurs from New Jersey south to Florida and west to Kansas, Oklahoma, and Texas.
This perennial grass forms tufts of branching stems reaching 120 to 150 centimeters in maximum height. The inflorescence is made up of pairs of feathery racemes, each of which contains pairs of spikelets. Each pair is made up of one fertile spikelet and one sterile. The fertile spikelet has an awn up to 2.5 centimeters long. The spikelets are coated in very long, silvery hairs. In the Great Plains, the grass blooms in August through October. In the Carolinas blooming occurs in September and October and in Louisiana the grass blooms in the fall. One variety of this species, the Florida endemic var. cabanisii, has been treated as a separate species, A. cabanisii.
This grass grows in pine and oak forests and on prairie. It is dominant in the pine savanna around the Texas-Louisiana border. It grows in disturbed habitat types such as grazed pastures, ditches, and abandoned crop fields. Old fields in the southern United States are often colonized with the grass and its relative, broomsedge (Andropogon virginicus). In the ecological succession of abandoned fields in the region, the bluestem grasses grow after various annual and perennial weeds but before pines move in to shade them out.
Cattle graze on the grass. Northern bobwhite are known to nest in bunches of it.


Anemonastrum canadense, synonym Anemone canadensis, the Canada anemone, round-headed anemone, round-leaf thimbleweed, meadow anemone, windflower, or crowfoot, is a herbaceous perennial flowering plant in the family Ranunculaceae. It is native to moist meadows, thickets, streambanks, and lakeshores in North America, spreading rapidly by underground rhizomes. It is valued for its white flowers.


The species was first described in 1768 by Carl Linnaeus, as Anemone canadensis. As traditionally and broadly circumscribed, the genus Anemone has repeatedly been shown not to be monophyletic, with genera such as Clematis and Pulsatilla embedded within it. As part of creating monophyletic genera, Sergei Mosyakin expanded the genus Anemonastrum to include Anemone canadensis as Anemonastrum canadense.


Anemonastrum canadense is native to Canada and the west central and eastern United States.


Anemonastrum canadense was used medically by North American Indigenous peoples as an astringent, as a styptic for wounds, sores, nosebleeds, and as an eyewash. The root was respected by Plains tribes and used for many ailments.


It is likely that most anemones contain similar caustic irritants to other members of the family Ranunculaceae.


Anemone cylindrica is an upright growing, clump forming herbaceous flowering plant species in the buttercup family Ranunculaceae. Plants grow 30–100 centimetres (12–39 in) tall, flowering early summer but often found flowering till late summer, the flowers are greenish-white. After flowering, the fruits are produced in a dense rounded columned spikes 20–35 millimetres (0.79–1.38 in) long. When the fruits, called achenes, are ripe they have gray-white colored, densely woolly styles, that allow them to blow away in the wind.
Anemone cylindrica is native to north central North America where it can be found growing in prairies, in dry open woods, along roadsides and in pastures.
Anemone cylindrica is one of several plants known as thimbleweed.


Anemonoides nemorosa (syn. Anemone nemorosa), the wood anemone, is an early-spring flowering plant in the buttercup family Ranunculaceae, native to Europe. Other common names include windflower, European thimbleweed, and smell fox, an allusion to the musky smell of the leaves. It is a perennial herbaceous plant growing 5–15 cm (2–6 in) tall.


Anemonoides nemorosa is a rhizomatous herbaceous perennial plant less than 30 centimetres (12 in) in height. The compound basal leaves are palmate or ternate (divided into three lobes). They grow from underground root-like stems called rhizomes and die back down by mid summer (summer dormant).
The plants start blooming in spring, March to May in the British Isles soon after the foliage emerges from the ground. The flowers are solitary, held above the foliage on short stems, with a whorl of three palmate or palmately-lobed leaflike bracts beneath. The flowers are 2 centimetres (0.8 in) diameter, with six or seven (and on rare occasions eight to ten) tepals (petal-like segments) with many stamens. In the wild the flowers are usually white but may be pinkish, lilac or blue, and often have a darker tint on the backs of the tepals.


The yellow wood anemone (Anemonoides ranunculoides) is slightly smaller, with yellow flowers and usually without basal leaves.
Wood sorrel Oxalis acetosella, which grows in similar shaded places, can be readily distinguished by its ternate and clover-like leaves and smaller flowers with 5 white petals and 5 sepals.


The native range of Anemonoides nemorosa extends across Europe to western Asia, reaching as far south as the Caucasus Mountains in Turkey. It has been introduced into New Zealand and elsewhere. In North America, there are naturalized populations at well-known sites in Newfoundland, Quebec, and Massachusetts.
A. nemorosa is often found in shady woods. The species is common in the British Isles but it spreads very slowly there, by as little as six feet per century, so it is often used as an indicator for ancient woodland.


The flowers are pollinated by insects, especially hoverflies. The seeds are achenes.


Many cultivars have been selected for garden use, The RHS Plant Finder 2008–2009 lists 70 cultivars sold by nurseries in the UK. Some of the most widely available are:
'Alba Plena' - double white
'Allenii'agm - large lavender-blue flowers, often with seven petals (named after James Allen, nurseryman)
'Bowles' Purple' - purple flowers (named after E.A. Bowles, plantsman and garden writer)
'Bracteata Pleniflora' - double, white flowers, with green streaks and a frilly ruff of bracts
'Robinsoniana'agm - pale lavender-blue flowers (named after William Robinson, plantsman and garden writer)
'Royal Blue' - deep blue flowers with purple backs
'Vestal'agm - white, anemone-centred flowers
'Virescens'agm - flowers mutated into small conical clusters of leaves
Those marked agm are recipients of the Royal Horticultural Society's Award of Garden Merit.
Anemonoides × lipsiensis, a hybrid between A. nemorosa and A. ranunculoides, has pale yellow flowers; A. × lipsiensis 'Pallida' is the best-known result of this cross. It has also been awarded the AGM.


Anemonoides ranunculoides (syn. Anemone ranunculoides), the yellow anemone, yellow wood anemone, or buttercup anemone, is a species of herbaceous perennial plant that grows in forests across Europe to western Asia, and less frequently in the Mediterranean region. It is occasionally found as a garden escape.


Growing to 5–15 centimetres (2.0–5.9 in) tall, the plant is herbaceous, dying back down to its root-like rhizomes by mid summer. The rhizomes spread just below the earth surface and multiply quickly, contributing to its rapid spread in woodland conditions. The flower is about 1.5 centimetres (0.59 in) diameter, with from five to eight petal-like segments (actually tepals) of rich yellow colouring. In its native range, it flowers between March and May.


The native range of Anemonoides ranunculoides extends across Continental Europe to southwest Siberia, reaching as far south as the Caucasus Mountains in Turkey. The species has been introduced into Great Britain and elsewhere. In Canada, there is a naturalized population at a well-known site in Quebec.


The plant is widely grown as a garden plant, especially by rock garden and alpine garden enthusiasts. It has been awarded an Award of Garden Merit or AGM, H4 (hardy throughout the British Isles) by the Royal Horticultural Society. The double-flowered form 'Pleniflora' (sometimes listed as 'Flore Pleno') is also a recipient of the award. Anemone ranunculoides 'Frank Waley', a larger-growing, more robust cultivar, is sometimes available, as are the miniature subspecies A. ranunculoides subsp. wockeana and a selection known as A. ranunculoides 'Laciniata', with finely divided leaves.


Anemonoides sylvestris (syn. Anemone sylvestris), known as snowdrop anemone or snowdrop windflower, is a perennial plant flowering in spring, native to meadows and dry deciduous woodlands of central and western Europe and temperate Asia. It forms spreading patches, sometimes aggressively spreading.
Another name is wood anemone, but this more commonly refers to the European A. nemorosa or the North American A. quinquefolia.


The species grows 1–1.5 feet (0.30–0.46 m) tall with white flowers which bloom in April. Flowers have five petals with yellow anthers in the center and are fragrant.


The monotypic genus Anemopsis has only one species, Anemopsis californica, with the common names yerba mansa or lizard tail.
It is a perennial herb in the lizard tail family (Saururaceae) and prefers very wet soil or shallow water.


It is native to southwestern North America in northwest Mexico and the Southwestern United States from California to Oklahoma and Texas to Kansas to Oregon. It grows in wet, alkaline marsh and creek edges.


As it matures, the visible part of the plant develops red stains, eventually turning bright red in the fall.


Yerba mansa is showy in spring when in bloom. The iconic white "flowers" (actually reduced inflorescences, or pseudanthia) are borne in early spring, and are surrounded by 4–9 large white bracts.
Similar to the family Asteraceae, what appears to be a single bloom is in reality a dense cluster of individually small flowers borne in an inflorescence.  In this species the inflorescence is conical and has five to ten large white bracts beneath it, so that along with the tiny white florets, the whole structure is quite striking when it blooms in spring.  The conical structure develops into a single, tough fruit that can be carried downstream to spread the tiny, pepper-like seeds.


In her book on herbs of the southwestern USA, Dr. Soule discusses the common name.  "Yerba mansa is one of those names which confounds linguists.  Yerba is Spanish for herb, and thus one would think that mansa is also from Spanish as well, but all indications point to the fact that it is not.  Mansa means tame, peaceful, calm in Spanish, and the plant has no sedative effect, nor did local people ever use it as a calming agent.  Its primary use is as an antimicrobial, antibacterial, and antifungal.  The most likely explanation is that mansa is a Spanish alteration of the original native word for the plant, now lost in the depths of time." Hartweg, who collected it at León, Guanajuato in 1837, recorded the local name as yerba del manso. It is also known as yerba del manso in northern Baja California. The word "manso" could be short for "remanso" (backwater) which would agree with the areas where the plant thrives.


Yerba mansa is used as an antimicrobial, an antibacterial, and to treat vaginal candidiasis.
Yerba mansa is used to treat inflammation of the mucous membranes, swollen gums and sore throat.  An infusion of roots can be taken as a diuretic to treat rheumatic diseases like gout by ridding the body of excess uric acid, which causes painful inflammation of the joints. Yerba mansa prevents the buildup of uric acid crystals in the kidneys which could cause kidney stones if left untreated. A powder of dried root can be sprinkled on infected areas to alleviate athlete's foot or diaper rash.
Yerba mansa is versatile, it can be taken orally as a tea, tincture, infusion or dried in capsule form. It can be used externally for soaking inflamed or infected areas. It can be ground and used as a dusting powder. Some people in Las Cruces, New Mexico use the leaves to make a poultice to relieve muscle swelling and inflammation. The leaves and roots have also been used to heal and disinfect wounds and sores.


In the deserts of California, yerba mansa is being used as turf in public parks and ground cover in gardens.


Angelica sylvestris or wild angelica is a species of flowering plant, native to Europe and central Asia. An annual or short-lived perennial growing to a maximum of 2.5 metres (8.2 ft), it has erect purplish stems and rounded umbels of minuscule white or pale pink flowers in late summer.


The Latin specific epithet sylvestris means “growing in woodland”. However it tolerates a range of conditions including fields, hedgerows, open woods, marshes and fens. It will grow in light (sandy), medium (loamy) and heavy (clay) soils.
It has recently been determined to be an invasive weed in New Brunswick and Cape Breton, Nova Scotia, Canada. "According to the New Brunswick Invasive Species Council, unless this species is controlled, Woodland Angelica could spread throughout Canada, overwhelming other vegetation." The flowers are visited by a wide array of insects and are thus characterised by a generalised pollination system.
Adult wasps of Dolichovespula norwegica are known to feed off the nectar provided by A. sylvestris.


A. sylvestris is cultivated in gardens. The cultivar 'Ebony', with pink flowers, has gained the Royal Horticultural Society’s Award of Garden Merit.
It was used as a vegetable until the 20th century. The plant can be stored. The stem was eaten fresh, and the leaves could be boiled to a stew for storage or cooked with milk. The plant has also been used for dyeing.


The anhinga (/ænˈhɪŋɡə/; Anhinga anhinga), sometimes called snakebird, darter, American darter, or water turkey, is a water bird of the warmer parts of the Americas. The word anhinga comes from the Brazilian Tupi language and means "devil bird" or "snake bird". The origin of the name is apparent when swimming: only the neck appears above water so the bird looks like a snake ready to strike. They do not have external nares (nostrils) and breathe solely through their epiglottis.
The anhinga is placed in the darter family, Anhingidae, and is closely related to Indian (Anhinga melanogaster), African (Anhinga rufa), and Australian (Anhinga novaehollandiae) darters. Like other darters, the anhinga hunts by spearing fish and other small prey using its sharp, slender beak.


Anhinga species are found all over the world in warm shallow waters. The American anhinga has been subdivided into two subspecies, A. a. anhinga and A. a. leucogaster, based on their location. A. a. anhinga can be found mainly east of the Andes in South America and also the islands of Trinidad and Tobago. A. a. leucogaster can be found in the southern United States, Mexico, Cuba, and Grenada. A fossil species Anhinga walterbolesi has been described from the Late Oligocene to Early Miocene of Australia.
Only birds that live in the extreme north and south of their range migrate and do so based on temperature and available sunlight. Anhingas will migrate towards the equator during winter but this range is "determined by the amount of sunshine to warm the chilled birds". Although not in their usual range, anhingas have been found as far north as the states of Pennsylvania and Wisconsin in the United States.
Kettles of anhingas often migrate with other birds and have been described as resembling black paper gliders.


The anhinga is a large bird, measuring approximately 89 cm (35 in) in length (with a range of 75–95 cm (30–37 in)), with a 1.14 m (3.7 ft) wingspan. The A. a. anhinga subspecies is larger than A. a. leucogaster and has broader buffy tail tips. They weigh on average around 1.22 kg (2.7 lb), with a range of 1.04–1.35 kg (2.3–3.0 lb). The bill is relatively long (about twice the length of the head), sharply pointed, and yellow, and the webbed feet are yellow as well.
The male is a glossy black-green with the wings, base of wings, and tail a glossy black-blue. The tip of the tail is white. The back of the head and the neck have elongated feathers that have been described as gray or light purple-white. The upper back of the body and wings is spotted or streaked with white.
The female anhinga is similar to the male except that it has a pale gray-buff or light brown head, neck, and upper chest. The lower chest or breast is a chestnut color, and the back is browner than that of the male.
The hatchling starts out bald but gains tan down within a few days of hatching. Within two weeks the tan down is replaced by white down. Three weeks after hatching, the first juvenile feathers appear. Juveniles are mostly brown until they first breed usually after the second or third winter.
This bird is often mistaken for the double-crested cormorant due to its similar size and shape, although the two species can be differentiated by their tails and bills. The tail of the anhinga is wider and much longer than that of the cormorant. The bill of the anhinga is pointed, while the bill of the cormorant has a hook-tip.


Anhingas swim with their webbed feet and pursue their prey, fish, under water and spear their prey by rapidly stretching out their neck. They come up to handle and swallow fish. Unlike ducks, ospreys and pelicans which coat their feathers with oil from their uropygial gland, the anhinga does not have waterproof feathers. Their feathers get soaked upon immersion in water. Therefore, they cannot stay floating on water for long periods of time. Their dense bones, wetted plumage and neutral buoyancy in water, allows them to fully submerge and search for underwater prey.
The anhinga cannot fly any extended distances with wet feathers. If it attempts to fly while its wings are wet, the anhinga has difficulty, flapping vigorously while "running" on the water for a short distance, often to avoid any perceived threats.  Like cormorants, the anhinga stands with wings spread and feathers fanned open in a semicircular shape, facing away from the sun, to dry its feathers and absorb heat.  Anhingas lose body heat relatively fast and their posture helps them absorb solar radiation from the sun to counter this. Because an anhinga in the drying position resembles a male turkey, it has been colloquially referred to as the 'water turkey' or 'swamp turkey'.


Anhingas feed on moderately sized wetland fishes, amphibians, aquatic invertebrates and insects. In Alabama, the anhinga's diet consists of fishes (such as mullet, sunfish, black bass, catfish, suckers, and chain pickerel), crayfish, crabs, shrimp, aquatic insects, tadpoles, water snakes and small terrapins. In Florida, sunfishes and bass, killifishes, and live-bearing fishes are primarily eaten by the anhingas. Other fish eaten include pupfish and percids.
Anhingas stalk fish underwater, mainly where there is some flora present. Once they locate their prey, they partly open their bill and stab the fish swiftly. For larger fish, they use both their jaws and use the lower jaw on small fish. If the fish is too large to forage, the anhinga stabs it repeatedly and then lets it go. The anhingas bring their capture to the surface of the water, toss it backwards and engulf it head-first.


The anhinga is protected in the US under the Migratory Bird Treaty Act of 1918. The number of individual anhingas has not been estimated but they are considered to be of least concern because of the frequency of their occurrence in their 15,000,000 km² (5,800,000 sq mi) global range.


The Australasian darter or Australian darter (Anhinga novaehollandiae) is a species of bird in the darter family, Anhingidae. It is found in Australia, Indonesia, and Papua New Guinea. It weighs around 2.6 kg and spans 86–94 cm (34–37 in) in length.


John Gould described the Australasian darter as Plotus novaehollandiae in 1847. Closely related to American (Anhinga anhinga), African (Anhinga rufa), and Oriental (Anhinga melanogaster) darters, the Australasian darter has been classed as a subspecies of the African or African plus Oriental darters. All four have also been classed as a single species. Examination of the leg bones indicates the three Old World species are more closely related to each other with the American species more divergent. Genetic analysis showed it differed from A. rufa to a degree equivalent to that between other separate species, and shifted consensus to treating the Australasian darter as a separate species.
Fossils of the Australasian darter have been recovered from several Pleistocene strata in Australia.
As well as Australasian darter, common names given to the species include darter, diver, needle-beak shag, shag, and snake-bird. The Noongar people of southwestern Australia call it mimal. Gould also called it the New Holland darter or New Holland devil-bird.


The Australasian darter is a slim bird measuring 86–94 cm (34–37 in) long with a snakelike slender neck. The male has black plumage with a white streak down the side of its head and neck, while the female has white underparts.


Typical habitat is freshwater or brackish wetlands more than 0.5 m deep with fallen trees or logs and vegetated banks; less commonly, darters are found in inland saltwater environments. The Australasian darter is found in the lowlands of New Guinea, New Britain, the Moluccas and the Lesser Sunda Islands. It is found across Australia, though not in the Great Sandy or Great Victoria Deserts or Nullarbor Plain,.. It is an uncommon vagrant to Tasmania.


Anisocarpus madioides (syn. Madia madioides) is a North American species of flowering plant in the family Asteraceae known by the common name woodland madia.


Anisocarpus madioides is a perennial herb growing up to about 75 centimeters in height, its stem coated in rough hairs and stalked resin glands. The lower leaves are up to 12 centimeters long, oppositely arranged, and fused around the stem at the bases. The upper leaves are much smaller and often alternately arranged. The inflorescence produces several flower heads on long peduncles, each with a rounded involucre of glandular phyllaries. The heads bear yellow ray florets up to a centimeter long and many disc florets. The fruit is an achene a few millimeters long, usually with a small pappus. Flowers bloom April to September.


Anisocarpus madioides is native to the west coast of North America on Vancouver Island in the Canadian Province of British Columbia and in the US States of Washington, Oregon, and California. It is a plant of forest and woodland habitat. Most of the populations occur in the Cascades and in the Coast Ranges from Vancouver Island to San Luis Obispo County, but there are additional collections from the foothills of the northern Sierra Nevada and from the Agua Tibia Mountains of San Diego County.


The trees grow to up to 12 m. They have narrow, gray trunks and sometimes grow in clumps. The leaves are ovate to oblong, each with an acute tip, 8–15 cm long and 4–6 cm broad with a prominent midrib. The upper surface is light to dark green. Leaves of the A. glabra are said to have a distinct smell, similar to green apples, that can distinguish it from mangroves. The fruit is oblong through spherical and apple-sized or larger, 7–15 cm long and up to 9 cm diameter, and falls when it is green or ripening yellowish. It disperses by floating to new locations, and it is food for many animal species such as wild boar. Reproduction begins around two years of age. A fruit contains 100 or more convex, light yellow-brown seeds, about 1 cm long. A. glabra flowers have a short life-span, and have a diameter of 2–3 cm. The flowers have three outer petals as well as three inner petals. Compared to the pale yellow or cream color of the petals, the inner base of the A. glabra flower is a bright red. Its pollen is shed as permanent tetrads.


A. glabra thrives in wet environments. The seeds and fruit of this plant can be dispersed during wet seasons where they fall into swamps and rivers. This allows the seeds and fruits to spread to coastlines. A 2008 study found that A. glabra seeds can withstand floating in salt water and fresh water for up to 12 months. About 38% of those seeds can then germinate in soil, though A. glabra roots do not do well with constant flooding. Another study in 1998 found that even under intense flooding, the 12-month lifespan of A. glabra seedlings was unaffected; the growth rate of A. glabra trees did decrease however over a 6-month period. Compared to other Annona seeds and trees, the A. glabra is still more resilient to instances of flooding.


Unlike the other Annona species, the pulp of the fruit when ripe is yellow through orange instead of whitish.
The fruit is edible for humans and its taste is reminiscent of ripe Honeydew melon.
It can be made into jam, and it is a popular ingredient of fresh fruit drinks in Maldives. In the older days the seeds were crushed and cooked in coconut oil and applied to hair to get rid of lice
The flesh is sweet-scented and agreeable in flavor, but it has never attained general popular use unlike soursop and other related fruits. Experiments in South Florida have been conducted to use it as a superior rootstock for sugar-apple or soursop. While the grafts initially appear to be effective, a high percentage of them typically fail over time. Soursop on pond-apple rootstock has a dwarfing effect.
Recent research suggests that its alcoholic seed extract contains anticancer compounds that could be used pharmaceutically.


It is a very troublesome invasive species in northern Queensland in Australia and Sri Lanka, where it grows in estuaries and chokes mangrove swamps. The A. glabra tree was introduced to North Queensland sometime around 1912 as both a rootstock for similar Annona species such as Annona atemoya, the custard apple. A. glabra seedlings carpet the banks and prevent other species from germinating or thriving. It also affects farms as it grows along fencelines and farm drains. It also invades and transforms undisturbed areas. This can be observed in the case of Australia’s Eubenangee Swamp National Park where an outbreak occurred due to poor wetland management.
In Australia, A. glabra seeds can be spread by the southern cassowary. Seeds of the fruit have been found in cassowary dung with dispersal distances of up to 5212 m recorded in one 2008 study in the journal Diversity and Distributions. The southern cassowary itself however is an endangered species in Australia. According to the Australian government’s Department of the Environment and Energy, there is only around 20-25% of cassowary habitat remaining. Additionally, part of the government’s recovery plan includes actions towards establishing nurseries filled with plants that the cassowary consumes. Because the A. glabra is among the foods eaten by southern cassowary, revegetation may be necessary to ensure that cassowary have alternative food sources available. When the A. glabra population is controlled, natural vegetation can regenerate without human intervention.
Because of its impact on the environment as an invasive weed, the Australian government classifies the A. glabra as a Weed of National Significance (WONS). Additionally, the A. glabra was considered the highest ranked species in 2003 in a Wet Tropics bioregion weed risk assessment. In Sri Lanka it was introduced as a grafting stock for custard apples and spread into wetlands around Colombo.


The Australian government views the A. glabra as a weed, and as such offers through its Department of the Environment and Energy a control plan created in 2001 for citizens that aims at eliminating the A. glabra by 20 years. The plan includes six steps that property owners can take to determine how to control and monitor an outbreak of A. glabra as well as how to minimize financial damage. To disincentivize the cultivation and spread of A. glabra by humans, its sale and entry is banned throughout most of Australia.
Options for the control of the A. glabra include fire, chemical, and mechanical controls including combinations of the three types. The best time of year to do so according to the government of Australia is during the time between August to November, which is the dry season. There are currently no studies that have looked at the biological control of A. glabra within Australia. Without studies, any actions taken to eliminate the A. glabra with biological controls could inadvertently affect native Australian apple species that belong to the same family.


Anoda cristata is a species of flowering plant in the mallow family known by many common names, including spurred anoda, crested anoda, and violettas. It is native to North and South America. It is known throughout the rest of the Americas as well as Australia as an introduced species and often a noxious weed. It has been found as a weed in Belgium. Naturally, it is often found near streams, in moist meadows, and in disturbed areas.
This is an annual herb reaching a maximum erect height between one half and one meter. The stem is ridged and branching. The plant is variable in morphology, especially in leaf shape, but leaves are usually somewhat triangular, and hairy. Solitary flowers grow in the leaf axils on long pedicels. The flower is 2 to 3 centimeters wide, with pointed green to reddish sepals and 5 petals, which may be blueish-purple or reddish-pink in color. The fruit is a bristly, disc-shaped capsule with 9 to 20 segments. Each segment produces a seed. This is sometimes an agricultural weed, especially of soybeans. It is tolerated as a weed of crop fields in parts of Mexico, and even fostered, because it is eaten and used as a source of medicinal remedies.


Anomodon attenuatus, commonly known as anomodon moss, is a species of moss in the family Thuidiaceae. It has a wide-ranging distribution and can be found from Canada to Central America and the Caribbean as well as in Europe and Asia (India, eastern Russia, and Turkey).


A. laticlavia adults are 7 to 12mm. It is recognizable with variable width black suture on a reddish-brown elytron. Males' front legs are relatively large.A. laticlavia is in the unranked taxon Camptosomata, or case-bearing leaf beetles.


Larvae are subterranean root or litter feeders. Reported adult host-plants include legumes, oaks, willows, persimmon, and ragweed. Some Florida populations are identified as a subspecies.


The yellow crazy ant (Anoplolepis gracilipes), also known as the long-legged ant or Maldive ant, is a species of ant, thought to be native to West Africa or Asia.  They have been accidentally introduced to numerous places in the world's tropics.
The yellow crazy ant has colloquially been given the modifier "crazy" on account of the ant's erratic movements when disturbed. Its long legs and antennae make it one of the largest invasive ant species in the world.
Like several other invasive ants, such as the red imported fire ant (Solenopsis invicta), the big-headed ant (Pheidole megacephala), the little fire ant (Wasmannia auropunctata), and the Argentine ant (Linepithema humile), the yellow crazy ant is a "tramp ant", a species that easily becomes established and dominant in new habitat due to traits such as aggression toward other ant species, little aggression toward members of its own species, efficient recruitment, and large colony size.
It is on a list of "one hundred of the world's worst invasive species" formulated by the International Union for Conservation of Nature (IUCN), having invaded ecosystems from Hawaii to the Seychelles, and formed supercolonies on Christmas Island in the Indian Ocean.


Anoplolepis gracilipes is a relatively large, yellow to orange ant with long legs, large eyes and extremely long antennal scapes.
Although A. gracilipes is the only invasive species in the genus Anoplolepis, there are several other genera for which it can be mistaken. Both Leptomyrmex and Oecophylla can be confused with Anoplolepis because of their similar sizes and very long limbs. Anoplolepis can be distinguished from Leptomyrmex by the presence of an acidopore, while Anoplolepis can be distinguished from Oecophylla by the more compact petiole. Although both of these genera occur in the Pacific, neither contain any invasive species.
Several species of invasive ants belonging to the genera Camponotus and Paratrechina can appear similar to A. gracilipes. Although several invasive species of Pheidole can also be slender-bodied with long legs and long antennal scapes, they can be separated from A. gracilipes by their two-segmented waists.
A. gracilipes is widespread across the tropics, and populations are especially dense in the Pacific region. The species is most infamous for causing the ecological "meltdown" of Christmas Island. Although widespread across the Pacific, A. gracilipes can cause significant damage to native biological diversity.  Strong quarantine measures are encouraged to keep it from spreading to new localities.


The yellow crazy ant's natural habitats are the moist tropical lowlands of Southeast Asia, and surrounding areas and islands in the Indian and Pacific Oceans. It has been introduced into a wide range of tropical and subtropical environments including northern Australia, some of the Caribbean islands, some Indian Ocean islands (Seychelles, Madagascar, Mauritius, Réunion, the Cocos Islands and the Christmas Islands) and some Pacific islands (New Caledonia, Hawaii, French Polynesia, Okinawa, Vanuatu, Micronesia, Johnston Atoll, and the Galapagos archipelago). The species has been known to occupy such agricultural systems as cinnamon, citrus, coffee and coconut plantations. Because yellow crazy ants have generalized nesting habits, they are able to disperse via trucks, boats and other forms of human transport.
Crazy ant colonies naturally disperse through "budding", i.e. when mated queens and workers leave the nest to establish a new one, and only rarely through flight via female winged reproductive forms. Generally, colonies that disperse through budding have a lower rate of dispersal, requiring human intervention to reach distant areas. It has been recorded that A. gracilipes moves as much as 400 m (1,300 ft) a year in the Seychelles. A survey on Christmas Island, however, yielded an average spreading speed of 3 meters (9.8 ft) per day, the equivalent of one kilometer (0.6 mile) per year.


In Australia, yellow crazy ants have been found at more than 30 sites in Queensland, and in Arnhem Land in the Northern Territory, where a large scattered population exists. A single New South Wales infestation was detected and eradicated, and, in Western Australia, yellow crazy ants have been intercepted in shipping freight arriving at Fremantle.
Queensland's main infestation is 830 hectares (2,100 acres) in and around Wet Tropics of Queensland rainforest, a World Heritage Site. The Northern Territory infestation covers 2,500 square kilometres (970 sq mi), an area larger than the Australian Capital Territory.
Climate modelling indicates yellow crazy ants could spread across northern Australia from Queensland to Western Australia, across much of Queensland and into coastal and inland parts of New South Wales.  Areas with the most ideal habitat and climatic conditions, such as the Wet Tropics of Queensland rainforests, are likely to experience the highest impacts.
A cost–benefit analysis by the Queensland government undertaken in 2012 found that yellow crazy ants could cost Australia's economy over A$3 billion if the ants were not treated. This analysis did not take potential impacts on Australia's biodiversity into account. The known impacts of crazy ants in tropical rainforests overseas may provide useful insights into these impacts, bearing in mind that the most significant impacts are associated with relatively small islands, such as Christmas Island.


Crazy ants have had a profound impact on the biodiversity of Christmas Island.
The crazy ant has a significant destructive impact on the island's ecosystem, killing and displacing crabs on the forest floor. The super-colonies also devastate crab numbers migrating to the coast. This has seen a rapid depletion in the number of land crabs — killing up to 20 million of them — which are vital to Christmas Island's biodiversity; land crabs are a keystone species in the forest ecology: they dig burrows, turn over the soil, and fertilize it with their droppings.
Seedlings that were previously eaten by crabs started to grow and, as a result, changed the structure of the forest. Weeds have spread into the rainforest because there are no crabs to control them. One of the most noticeable changes in the forest is the increased numbers of the stinging tree Dendrocnide peltata, which now flourishes in many areas frequently visited by humans. The forest canopy also changed as the scale insects tended by yellow crazy ants multiplied and killed mature trees.
Christmas Island red crabs are completely wiped out in infested areas. Populations of other ground and canopy dwelling animals, such as reptiles and other leaf litter fauna, have also decreased. During crab migrations, many crabs move through areas infested with ants and are killed. Studies show that the ant has displaced an estimated 15–20 million crabs by occupying their burrows, killing and eating resident crabs, and using their burrows as nest sites. This factor has greatly depleted red crabs, and made their annual land migrations far more perilous.
Although crazy ants do not bite or sting, they spray formic acid as a defence mechanism and to subdue their prey. In areas of high ant density, the movement of a land crab disturbs the ants and, as a result, the ants instinctively spray formic acid as a form of defence. The high levels of formic acid at ground level eventually overwhelm the crabs, and they are usually blinded then eventually die from dehydration (while attempting to flush off the formic acid) and exhaustion. As the dead crabs decay, the protein becomes available to the ants.
Crazy ants kill fauna, but encourage scale insects. Increased densities of scale insects cause forest die back, and even the death of large forest trees. These changes create a cascade of negative impacts, including weed invasion, significantly altering the forest landscape.


To reduce the impacts of crazy ants on red crabs and Christmas Island's ecosystems the Parks Australia carried out a major aerial baiting program in 2009, to follow up the first aerial baiting conducted in 2002. The first step was conducting an extensive island-wide survey to determine the exact locations of the supercolonies. For several months, staff traversed the island surveying over 900 sites. The result was a map of crazy ant supercolonies and red crab burrow densities, together with other biodiversity data.
In September 2009, a helicopter was used to precisely bait crazy ant supercolonies, which covered 784 hectares (1,940 acres) of the island. A very low concentration of fipronil bait (0.1%) was used to control the ants. Monthly monitoring of these baited supercolony sites shows that crazy ant densities were reduced by 99%.
Park staff placed a high emphasis on minimising non-target impact of baiting. Food lures were dropped from a helicopter to attract robber crabs away from areas that were about to be baited. This technique, combined with the low concentration fipronil bait, proved to be highly successful with extremely low numbers of robber crabs and no red crabs known to be killed by the baiting.
While baiting has slowed the decline of the red crab, its effects on the crazy ant populations are only temporary, as escaping colonies invade the treated areas again, and it is expensive, requiring much man power. In an effort to find a better control, after research, Australian Parks in December 2016 imported Tachardiaephagus somervillei, a small (2 millimetres (5⁄64 in)) wasp and began breeding them for release. The wasp, which attacks only scale insects, is a voracious predator of what is believed to be one of the crazy ant's largest source of honeydew on Christmas Island, the yellow lac scale insect.
Researchers from La Trobe University in Melbourne, funded by Parks Australia, began looking for biological controls in 2009. While the ants are omnivores, studies have shown honeydew is an important part of the diet of Christmas Island crazy ants. Samples of ants taken from colonies that are growing rapidly have more honeydew in their diet than when the colonies decline. Further, restricting access to honeydew, by binding trees where the scale insects feed, dramatically reduced the colony as ant activity on the ground fell by 95% in just four weeks. In the laboratory, colonies with limited sources of sugar were compared to colonies with access to abundant sugar. Those with abundant sugar had more fertile queens and lower death rates among workers. The workers were also more aggressive toward other ant species and explored their environments more. This is believed to show why the ants decline when deprived of access to scale insects in the field, and confirm reduced honeydew will greatly reduce the ants' ability to form super colonies.
While controlling the yellow lac scale insect is expected to control the yellow crazy ant on Christmas Island, on mainland Australia it is thought this would not help. There are at least a dozen honeydew producing insects as well as extrafloral nectar from native acacia trees, all of which fuel yellow crazy ants.
Experts continue to call for a fully funded, long term baiting program on mainland Australia.


Anredera cordifolia, commonly known as the Madeira-vine or mignonette vine, is a South American species of ornamental succulent vine of the family Basellaceae. The combination of fleshy leaves and thick aerial tubers makes this a very heavy vine. It smothers trees and other vegetation it grows on and can easily break branches and bring down entire trees on its own.


Anredera cordifolia is an evergreen climber that grows from fleshy rhizomes. It has bright green, heart-shaped, fleshy shiny leaves 4–13 cm long. Wart-like tubers are produced on aerial stems and are a key to identifying the plant.
From late summer to autumn, it produces masses of small, fragrant, cream-coloured flowers on dependent racemes, which may be up to 30 cm (12 in) in length. The plant spreads via the tubers, which detach very easily.


Anredera cordifolia can reproduce through the proliferation of tubers and also from rhizome fragments that may be broken off. Although this species has both male and female flowers they rarely reproduce sexually and produce seed. This species often spreads through its own vegetative growth, but can easily be transported by human activities. If fragments end up in waterways, they are easily transported to new locations in this manner.
Seedlings were found well away from habitation, roads and streams in Australia from 1988 onwards, leading to the conclusion that the species produces seeds there.


It is native to Bolivia, Brazil, Paraguay, Uruguay and Argentina in South America. It has been introduced to Africa, the Australasia–Pacific region, Europe, and North America; it is considered an invasive species in many tropical and sub-tropical localities.


Madeira vine can be cooked by frying with olive oil and garlic. Once cooked, it tastes silky and yummy. It’s a great food to have as a vegetable side-dish.


The greater white-fronted goose (Anser albifrons) is a species of goose related to the smaller lesser white-fronted goose (A. erythropus). It is named for the patch of white feathers bordering the base of its bill, in fact albifrons comes from the Latin albus "white" and frons "forehead".  In Europe it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America.


Greater white-fronted geese are 64–81 cm (25–32 in) in length, have a 130–165 cm (51–65 in) wingspan, and weigh 1.93–3.31 kg (4 lb 4 oz – 7 lb 5 oz). They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the greater white-fronted goose lacks the yellow eye-ring of that species, and the white facial blaze does not extend upwards so far as in lesser.
The male is typical larger in size, both sexes are similar in appearance—greyish brown birds with light grey breasts dappled with dark brown to black blotches and bars. Both males and females also have a pinkish bill and orange legs and feet.
Greater white-fronted geese make a variation of sounds, but notably the most recognizable is the high pitched cackle that can be imitated by the sounds "he-he." There is a distinct breaking of the note from the first cackle to the second.


The greater white-fronted goose is divided into five subspecies. The nominate subspecies, the European white-fronted goose (A. a. albifrons) breeds in the far north of Europe and Asia and winters further south and west in Europe.
Three other restricted-range races occur in northern North America: Gambel's white-fronted goose (A. a. gambeli) in interior northwestern Canada and wintering on the coast of the Gulf of Mexico, slightly larger than the nominate form, the Pacific white-fronted goose  (A. a. frontalis) and the tule goose (A. a. elgasi) in southwest Alaska, largest and longest-billed of all, both wintering in California. All these races are similar in plumage, differing only in size.
The very distinct Greenland white-fronted goose (A. a. flavirostris) breeding in western Greenland, is much darker overall, with only a very narrow white tip to the tail (broader on the other races), more black barring on its belly and usually has an orange (not pink) bill. It winters in Ireland and western Scotland.
Birds breeding in the far east of Siberia east to Arctic Canada, wintering in the United States and Japan, have been described as A. a. frontalis on the basis of their slightly larger size and a marginally longer bill. Another putative East Asian subspecies (A. a. albicans) has also been described. A 2012 study has found that frontalis and albicans do not merit subspecies status, the former being synonymised with gambeli and the latter with the nominate subspecies; this study found that these forms had been named on the wintering grounds from specimens whose breeding grounds were unknown.
Ecological studies in 2002 suggest the Greenland birds should probably be considered a separate species from A. albifrons. Of particular interest is its unusually long period of parental care and association, which may last several years and can include grandparenting, possibly unique among the Anseriformes.


The pink-footed goose (Anser brachyrhynchus) is a goose which breeds in eastern Greenland, Iceland and Svalbard. It is migratory, wintering in northwest Europe, especially Ireland, Great Britain, the Netherlands, and western Denmark. The name is often abbreviated in colloquial usage to "pinkfoot" (plural "pinkfeet"). Anser is the Latin for "goose", and brachyrhynchus comes from the ancient Greek brachus "short" and rhunchos "bill".
It is a medium-sized goose, 60–75 cm (24–30 in) long, the wingspan 135–170 cm (53–67 in), and weighing 1.8–3.4 kg (4.0–7.5 lb). It has a short bill, bright pink in the middle with a black base and tip, and pink feet. The body is mid-grey-brown, the head and neck a richer, darker brown, the rump and vent white, and the tail grey with a broad white tip. The upper wing-coverts are of a somewhat similar pale bluish-grey as in the greylag goose, and the flight feathers blackish-grey. The species is most closely related to the bean goose Anser fabalis (having even been treated as a subspecies of it at times in the past), sharing a similar black-and-coloured pattern bill, but differing in having pink on the bill and legs where the bean goose is orange, and in the paler, greyer plumage tones. It is similar in size to the small rossicus subspecies of bean goose, but distinctly smaller than the nominate subspecies fabalis. It produces a medley of high-pitched honking calls, being particularly vocal in flight, with large skeins being almost deafening.


There are two largely discrete populations of pink-footed goose. The Greenland and Iceland population winter in Great Britain, while the Svalbard population winters in the Netherlands and Denmark, with small numbers also in Norway (where it is common on migration), northern Germany, and Belgium.
Populations have risen spectacularly over the last 50 years, due largely to increased protection from shooting on the wintering grounds. Numbers wintering in Ireland and Great Britain have risen almost tenfold from 30,000 in 1950 to 292,000 in October 2004. The numbers wintering in Denmark and the Netherlands have also risen, with about 34,000 in 1993. The most important single breeding site, at Þjórsárver in Iceland (holding 10,700 pairs in 1970), was only discovered in 1951, by Sir Peter Scott and his team who made an expedition to seek the breeding grounds. Within Great Britain, the most important wintering areas are in Norfolk (147,000 in 2004), Lancashire (44,000 in 2004), and Aberdeenshire (primarily on autumn and spring passage). Large to huge wintering flocks graze on farmland; individual flocks can be spectacular, such as the 66,000 at Loch of Strathbeg, Aberdeenshire in early September 2003.


Despite the proximity to the large winter numbers in Great Britain, only very small numbers occur in Ireland and France. It is a rare vagrant to several other European countries and as far south as Morocco and the Canary Islands, and also to eastern Canada and the United States (from Newfoundland south to Pennsylvania).
The pink-footed goose is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.


The snow goose (Anser caerulescens) is a species of goose native to North America. Both white and dark morphs exist, the latter often known as blue goose. Its name derives from the typically white plumage. The species was previously placed in the genus Chen, but is now typically included in the "gray goose" genus Anser.
Snow geese breed north of the timberline in Greenland, Canada, Alaska, and the northeastern tip of Siberia, and spend winters in warm parts of North America from southwestern British Columbia through parts of the United States to Mexico. Snow goose populations increased dramatically in the 20th century.


In 1750 the English naturalist George Edwards included an illustration and a description of the snow goose in the third volume of his A Natural History of Uncommon Birds. He used the English name "The blue-winged goose". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay area of Canada by James Isham. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the snow goose with the ducks and geese in the genus Anas. Linnaeus included a brief description, coined the binomial name Anas caerulescens and cited Edwards' work. The snow goose is now placed in the genus Anser that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The scientific name is from the Latin anser, "goose", and caerulescens, "bluish", derived from caeruleus, "dark blue". The snow goose is the sister species to Ross's goose (Anser rossii).
Two subspecies are recognised:
A. c. caerulescens (Linnaeus, 1758) – lesser snow goose – breeds in northeast Siberia, north Alaska and northwest Canada, winters in south USA, north Mexico and Japan
A. c. atlanticus (Kennard, 1927) – greater snow goose – breeds in northeast Canada and northwest Greenland, winters in northeast USA
The greater snow goose is distinguished from the nominate form by being slightly larger. It nests farther north and east. The lesser snow goose can be found in two colour phases, the normal white-coloured animals and a dark grey-coloured "blue" phase. The greater snow goose is rarely seen in a blue phase.


The snow goose has two color plumage morphs, white (snow) or gray/blue (blue), thus the common description as "snows" and "blues". White-morph birds are white except for black wing tips, but blue-morph geese have bluish-grey plumage replacing the white except on the head, neck and tail tip. The immature blue phase is drab or slate-gray with little to no white on the head, neck, or belly. Both snow and blue phases have rose-red feet and legs, and pink bills with black tomia ("cutting edges"), giving them a black "grin patch". The colors are not as bright on the feet, legs, and bill of immature birds. The head can be stained rusty-brown from minerals in the soil where they feed. They are very vocal and can often be heard from more than a mile away.
White- and blue-morph birds interbreed and the offspring may be of either morph. These two colors of geese were once thought to be separate species; since they interbreed and are found together throughout their ranges, they are now considered two color phases of the same species. The color phases are genetically controlled. The dark phase results from a single dominant gene and the white phase is homozygous recessive. When choosing a mate, young birds will most often select a mate that resembles their parents' coloring. If the birds were hatched into a mixed pair, they will mate with either color phase.
The species is divided into two subspecies on the basis of size and geography. Size overlap has caused some to question the division. The smaller subspecies, the lesser snow goose (C. c. caerulescens), lives from central northern Canada to the Bering Straits area. The lesser snow goose stands 64 to 79 cm (25 to 31 in) tall and weighs 2.05 to 2.7 kg (4.5 to 6.0 lb). The larger subspecies, the greater snow goose (C. c. atlanticus), nests in northeastern Canada. It averages about 3.2 kg (7.1 lb) and 79 cm (31 in), but can weigh up to 4.5 kg (9.9 lb). The wingspan for both subspecies ranges from 135 to 165 cm (53 to 65 in).


Long-term pair bonds are usually formed in the second year, although breeding does not usually start until the third year. Females are strongly philopatric, meaning they will return to the place they hatched to breed.
Snow geese often nest in colonies. Nesting usually begins at the end of May or during the first few days of June, depending on snow conditions. The female selects a nest site and builds the nest on an area of high ground. The nest is a shallow depression lined with plant material and may be reused from year to year. After the female lays the first of three to five eggs, she lines the nest with down. The female incubates for 22 to 25 days, and the young leave the nest within a few hours of hatching.
The young feed themselves, but are protected by both parents. After 42 to 50 days they can fly, but they remain with their family until they are two to three years old.
Where snow geese and Ross's geese breed together, as at La Pérouse, they hybridize at times, and hybrids are fertile. Rare hybrids with the greater white-fronted goose, Canada goose, and cackling goose have been observed.


Snow geese breed from late May to mid-August, but they leave their nesting areas and spend more than half the year on their migration to-and-from warmer wintering areas. During spring migration (the reverse migration), large flocks of snow geese fly very high and migrate in large numbers along narrow corridors, more than 3,000 mi (4,800 km) from traditional wintering areas to the tundra.
The lesser snow goose travels through the Central Flyway, Mississippi Flyway, and Pacific Flyway across prairie and rich farmland to their wintering grounds on grassland and agricultural fields across the United States and Mexico, especially the Gulf coastal plain. The larger and less numerous greater snow goose travels through the Atlantic Flyway and winters on a relatively more restricted range on the Atlantic coastal plain. Traditionally, lesser snow geese wintered in coastal marsh areas where they used their short but strong bills to dig up the roots of marsh grasses for food. However, they have also since shifted inland towards agricultural areas, likely the cause behind the unsustainable population increase in the 20th century. This shift may help to contribute to increased goose survival rates, leading to overgrazing on tundra breeding grounds.
In March 2015, 2,000 snow geese were killed in northern Idaho from an avian cholera epidemic while flying their spring migration to northern Canada.


The snow goose is a rare vagrant to Europe but for a frequent escape from collections and an occasional feral breeder. Snow geese are visitors to the British Isles where they are seen regularly among flocks of brant, barnacle goose, and greater white-fronted goose. There is also a feral population in Scotland from which many vagrant birds in Britain seem to derive.
In Central America, vagrants are frequently encountered during winter.


The breeding population of the lesser snow goose exceeds 5 million birds, an increase of more than 300% since the mid-1970s. The population is increasing at a rate of more than five percent per year. Non-breeding geese (juveniles or adults that fail to nest successfully) are not included in this estimate, so the total number of geese is likely higher. Lesser snow goose population indices are the highest they have been since population records have been kept, and evidence suggests that large breeding populations are spreading to previously untouched sections of the Hudson Bay coastline. The cause of this overpopulation may be the heavy conversion of land from forest and prairie to agricultural usage in the 20th century.
Since the late 1990s, efforts have been underway in the U.S. and Canada to reduce the North American population of lesser snow and Ross's geese to sustainable levels due to the documented destruction of tundra habitat in Hudson Bay and other nesting areas. The Light Goose Conservation Order was established in 1997 and federally mandated in 1999. Increasing hunter bag limits, extending the length of hunting seasons, and adding new hunting methods have all been successfully implemented, but have not reduced the overall population of snow geese in North America.


The swan goose (Anser cygnoides) is a large goose with a natural breeding range in inland Mongolia, northernmost China, and the Russian Far East. It is migratory and winters mainly in central and eastern China. Vagrant birds are encountered in Japan and Korea (where it used to winter in numbers when it was more common), and more rarely in Kazakhstan, Laos, coastal Siberia, Taiwan, Thailand and Uzbekistan.
While uncommon in the wild, this species has been domesticated. Introduced and feral populations of its domestic breeds occur in many places outside its natural range. The wild form is also kept in collections, and escapes are not unusual amongst feral flocks of other Anser and Branta geese.


The swan goose is large and long-necked for its genus, wild birds being 81–94 cm (32–37 in) long (the longest Anser goose) and weighing 2.8–3.5 kg (6.2–7.7 lb) or more (the second-heaviest Anser, after the greylag goose, A. anser). The sexes are similar, although the male is larger, with a proportionally longer bill and neck; in fact the largest females are barely as large as the smallest males. Typical measurements of the wing are 45–46 cm (18–18 in) in males, 37.5–44 cm (14.8–17.3 in) in females; the bill is about 8.7–9.8 cm (3.4–3.9 in) long in males and 7.5–8.5 cm (3.0–3.3 in) in females. The tarsus of males measures around 8.1 cm (3.2 in). The wingspan of adult geese is 160–185 cm (63–73 in).
The upperparts are greyish-brown, with thin light fringes to the larger feathers and a maroon hindneck and cap (reaching just below the eye).  The remiges are blackish, as are the entire underwing and the white-tipped rectrices, while the upper- and undertail coverts are white. A thin white stripe surrounds the bill base. Apart from darker streaks on the belly and flanks, the underside is pale buff, being especially light on the lower head and foreneck which are sharply delimited against the maroon. In flight, the wings appear dark, with no conspicuous pattern. Uniquely among its genus, the long, heavy bill is completely black; the legs and feet, on the other hand, are orange as in most of its relatives. The eyes' irides are maroon. Juveniles are duller than adult birds, and lack the white bill base and dark streaks on the underside.
The voice is a loud drawn-out and ascending honking aang. As a warning call, a similar but more barking honk is given two or three times in short succession.
The karyotype of the swan goose is 2n=80, consisting of four pairs of macrochromosomes, 35 pairs of microchromosomes, and a pair of sex chromosomes. The two largest macrochromosome pairs as well as the Z (female) chromosome are submetacentric, while the third-largest chromosome pair is acrocentric and the fourth-largest is metacentric. The W chromosomes are acrocentric too, as are the larger microchromosomes, the smaller ones probably being telocentric. Compared to the greylag goose, there seems to have been some rearrangement on the fourth-largest chromosome pair.


It inhabits steppe to taiga and mountain valleys near freshwater, grazing on plants such as sedges (Cyperaceae), and rarely swimming. It forms small flocks outside the breeding season. In the winter, it grazes on plains and stubble fields, sometimes far from water. Birds return from the winter quarters around April, and the breeding season starts soon thereafter. It breeds as single pairs or loose groups near marshes and other wetlands, with nesting activity starting about May. The clutch is usually 5–6 but sometimes up to 8 eggs, which are laid in a shallow nest made from plants, placed directly on the ground, often on a small knoll to keep it dry. The precocial young hatch after about 28 days and become sexually mature at 2–3 years of age. Around late August/early September, the birds leave for winter quarters, where they gather in small groups to moult their worn plumage.
The swan goose was uplisted from Near Threatened to Vulnerable on the IUCN Red List in 1992 and further to Endangered in 2000, as its population is declining due to habitat loss and excessive hunting and (particularly on the Sanjiang Plain in China) egg collecting. But new research has shown it to be not as rare as it was believed, and consequently, it was downlisted to Vulnerable status again in 2008. Still, less than 500 pairs might remain in Russia, while in Mongolia numbers are unknown though about 1,000 were seen at Ögii Lake in 1977. Favorite wintering locations in China are Lake Dongting, Lake Poyang, the Yancheng Coastal Wetlands and other locations around the lower Yangtze River, where some 60,000 individuals may be found each year – though this may be almost the entire world population. Until the 1950s, the species wintered in small numbers (up to about 100 birds annually) in Japan, but habitat destruction has driven them away. Altogether, between 60,000 and 100,000 adult Swan Geese remain in the wild today.


Though the majority of domestic geese are descended from the greylag goose (A. anser), two breeds are direct descendants of the swan goose: the Chinese goose and the African goose. These breeds have been domesticated since at least the mid-18th century – perhaps even (in China) since around 1000 BC. They vary considerably from their wild parent in appearance, temperament, and ability to produce meat and eggs; the most conspicuous feature is the prominent bill knob and upright posture.
Charles Darwin studied goose breeds as part of his work on the theory of evolution. He noted that the external differences between Chinese geese and breeds descended from the Greylag goose belied a rather close relationship:
"The hybrids from the common and Chinese geese (A. cygnoides), species which are so different that they are generally ranked in distinct genera, have often bred in this country with either pure parent, and in one single instance they have bred inter se."


The species is currently classified as Vulnerable by the IUCN based on ongoing population declines and range losses, exacerbated by recent poor breeding success and unsustainable levels of hunting. Total population was estimated as 60–90,000 individuals in 2012.


The bar-headed goose (Anser indicus) is a goose that breeds in Central Asia in colonies of thousands near mountain lakes and winters in South Asia, as far south as peninsular India. It lays three to eight eggs at a time in a ground nest. It is known for the extreme altitudes it reaches when migrating across the Himalayas.


The grey goose genus Anser has no other member indigenous to the Indian region, nor any at all to the Ethiopian, Australian, or Neotropical regions. Ludwig Reichenbach placed the bar-headed goose in the monotypic genus Eulabeia in 1852, though John Boyd's taxonomy treats both Eulabeia and the genus Chen as subgenera of Anser.


The summer habitat is high-altitude lakes where the bird grazes on short grass. The species has been reported as migrating south from Tibet, Kazakhstan, Mongolia and Russia before crossing the Himalayas. The bird has come to the attention of medical science in recent years as having been an early victim of the H5N1 virus, HPAI (highly pathogenic avian influenza), at Qinghai. It suffers predation from crows, foxes, ravens, sea eagles, gulls and others. The total population may, however, be increasing, but it is complex to assess population trends, as this species occurs over more than 2,500,000 km² (970,000 sq mi).

The bar-headed goose is one of the world's highest-flying birds, having been heard flying across Mount Makalu – the fifth highest mountain on earth at 8,481 m (27,825 ft) – and apparently seen over Mount Everest – 8,848 m (29,029 ft) – although this is a second-hand report with no verification. This demanding migration has long puzzled physiologists and naturalists: "there must be a good explanation for why the birds fly to the extreme altitudes... particularly since there are passes through the Himalaya at lower altitudes, and which are used by other migrating bird species." In fact, bar-headed geese had for a long time not been directly tracked (using GPS or satellite logging technology) flying higher than 6,540 metres (21,460 ft), and it is now believed that they do take the high passes through the mountains. The challenging northward migration from lowland India to breed in the summer on the Tibetan Plateau is undertaken in stages, with the flight across the Himalaya (from sea-level) being undertaken non-stop in as little as seven hours. Surprisingly, despite predictable tail winds that blow up the Himalayas (in the same direction of travel as the geese), bar-headed geese spurn these winds, waiting for them to die down overnight, when they then undertake the greatest rates of climbing flight ever recorded for a bird, and sustain these climbs rates for hours on end, according to research published in 2011.
The 2011 study found the geese peaking at an altitude of around 6,400 m (21,000 ft). In a 2012 study that tagged 91 geese and tracked their migration routes, it was determined that the geese spent 95% of their time below 5,784 m (18,976 ft), choosing to take a longer route through the Himalayas in order to utilize lower-altitude valleys and passes. Only 10 of the tagged geese were ever recorded above this altitude, and only one exceeded 6,500 m (21,300 ft), reaching 7,290 m (23,920 ft). All but one of these high-altitude flights were recorded at night, which along with the early morning, is the most common time of day for geese migration. The colder denser air during these times may be equivalent to an altitude hundreds of meters lower. It is suspected by the authors of these two studies that tales of the geese flying at 8,000 m (26,000 ft) are apocryphal. Bar headed geese have been observed flying at 7,000 metres (23,000 ft).
The bar-headed goose migrates over the Himalayas to spend the winter in parts of South Asia (from Assam to as far south as Tamil Nadu. The modern winter habitat of the species is cultivated fields, where it feeds on barley, rice and wheat, and may damage crops. Birds from Kyrgyzstan have been seen to stopover in western Tibet and southern Tajikistan for 20 to 30 days before migrating farther south. Some birds may show high wintering site fidelity.
They nest mainly on the Tibetan Plateau. Intraspecific brood parasitism is noticed with lower rank females attempting to lay their eggs in the nests of higher ranking females.
The bar-headed goose is often kept in captivity, as it is considered beautiful and breeds readily. Records in Great Britain are frequent, and almost certainly relate to escapes. However, the species has bred on several occasions in recent years, and around five pairs were recorded in 2002, the most recent available report of the Rare Birds Breeding Panel. It is possible that, owing to a combination of frequent migration, accidental escapes and deliberate introduction, the species is becoming gradually more established in Great Britain. The bird is sociable and causes no problems for other birds. The feral population is believed to be declining in Great Britain due to overhunting.
The bar-headed goose has escaped or been deliberately released in Florida, U.S., but there is no evidence that the population is breeding and it may only persist due to continuing escapes or releases.


The main physiological challenge of bar-headed geese is extracting oxygen from hypoxic air and transporting it to aerobic muscle fibres in order to sustain flight at high altitudes. Flight is very metabolically costly at high-altitudes because birds need to flap harder in thin air to generate lift. Studies have found that bar-headed geese breathe more deeply and efficiently under low-oxygen conditions, which serves to increase oxygen uptake from the environment. The haemoglobin of their blood has a higher affinity for oxygen than that of low-altitude geese, which has been attributed to a single amino acid point mutation. This mutation causes a conformational shift in the haemoglobin molecule from the low-oxygen to the high-oxygen affinity form. The left-ventricle of the heart, which is responsible for pumping oxygenated blood to the body via systemic circulation, has significantly more capillaries in bar-headed geese than in lowland birds, maintaining oxygenation of cardiac muscle cells and thereby cardiac output. Compared to lowland birds, mitochondria (the main site of oxygen consumption) in the flight muscle of bar-headed geese are significantly closer to the sarcolemma, decreasing the intracellular diffusion distance of oxygen from the capillaries to the mitochondria.
Bar-headed geese have a slightly larger wing area for their weight than other geese, which is believed to help them fly at high altitudes. While this decreases the power output required for flight in thin air, birds at high altitude still need to flap harder than lowland birds.


The bar-headed goose has been suggested as being the model for the Hamsa of Indian mythology. Another interpretation suggests that the bar-headed goose is likely to be the Kadamb in ancient and medieval Sanskrit literature, whereas Hamsa generally refers to the swan.


The magpie goose (Anseranas semipalmata) is the sole living representative species of the family Anseranatidae. This common waterbird is found in northern Australia and southern New Guinea. As the species is prone to wandering, especially when not breeding, it is sometimes recorded outside its core range. The species was once also widespread in southern Australia, but disappeared from there largely due to the drainage of the wetlands where the birds once bred. Due to their importance to Aboriginal people as a seasonal food source, as subjects of recreational hunting, and as a tourist attraction, their expansive and stable presence in northern Australia has been "ensured protective management".


Magpie geese are unmistakable birds with their black and white plumage and yellowish legs. The feet are only partially webbed, and the magpie goose feeds on vegetable matter in the water, as well as on land. Males are larger than females. Unlike true geese, their moult is gradual, so no flightless periods result. Their voice is a loud honking.


This species is placed in the order Anseriformes, having the characteristic bill structure, but is considered to be distinct from the other species in this taxon. The related and extant families, Anhimidae (screamers) and Anatidae (ducks, geese, and swans), contain all the other taxa. The magpie goose is contained in the genus Anseranas and family Anseranatidae, which are monotypic now.
A cladistic study of the morphology of waterfowl found that the magpie goose was an early and distinctive offshoot, diverging after screamers and before all other ducks, geese, and swans.
This family is quite old, a living fossil, having apparently diverged before the Cretaceous–Paleogene extinction event — the relative Vegavis iaai lived some 68-67 million years ago. The fossil record is limited, nonetheless. The enigmatic genus Anatalavis (Hornerstown Late Cretaceous or Early Paleocene of New Jersey, USA - London Clay Early Eocene of Walton-on-the-Naze, England) is sometimes considered to be the earliest known anseranatid. Other Paleogene birds sometimes considered magpie-geese are the genera Geranopsis from the Hordwell Formation Late Eocene to the Early Oligocene of England and Anserpica from the Late Oligocene of Billy-Créchy (France).
The earliest known member of the group in Australia is Eoanseranas represented by fossils found in the late Oligocene Carl Creek Limestone of Queensland. Additional fossils from North America and Europe suggest that the family was spread across the globe during the late Paleogene period. The Australian distribution of the living species ties in well with the presumed Gondwanan origin of Anseriformes, but Northern Hemisphere fossils are puzzling. Perhaps the magpie geese were one of the dominant groups of Paleogene waterfowl, only to become largely extinct later.


The magpie goose is found in a variety of open wetland areas such as floodplains and swamps, where they wade and swim. They eat mostly vegetation such as dry grass blades, grass seeds, spike rush bulbs and wild rice.
It is fairly sedentary apart from some movement during the dry season. They are colonial breeders and are gregarious outside of the breeding season when they can form large and noisy flocks of up to a few thousand individuals. Its nest is on the ground (also in trees 5 m or more high), and a typical clutch is 5-14 eggs. Some males mate with two females, all of which raise the young, unlike some other polygamous birds. This may be beneficial when predation of young is high as chicks raised by trios are more likely to survive.
This species is plentiful across its range, although this is significantly reduced in comparison to the range at time of European settlement. The range once extended as far south as the Coorong and the wetlands of the southeast of South Australia and Western Victoria. For Australia as a whole, it is not threatened and has a controlled hunting season when numbers are large. However, most of the southern populations were extirpated in the mid-20th century by overhunting and habitat destruction. The species has been subject to reintroduction projects such as Bool Lagoon between Penola and Naracoorte. Populations in more northern areas have again reached a level where it can be regularly utilized by hunters, although not in the example provided. The magpie goose was listed as near threatened on the 2007 advisory list of threatened vertebrate fauna in Victoria. In the December 2007 Flora and Fauna Guarantee Act list of threatened fauna, it is also listed. As of early 2008, an Action Statement for the recovery and future management of this species had not been prepared.
With the advent of climate change, and more frequent seawater inundations of the current extensive freshwater floodplains, CSIRO scientists argue that magpie geese populations may be at risk.


The Kunwinjku of western Arnhem Land know this bird as manimunak. It became an important food item with the formation of wetlands about 1500 ya, and is depicted in rock art from this period.  Mimi figures are often shown holding goose-feather fans. In Yolŋu Matha the bird is known as gurrumaṯtji, or around Ramingining as gumang.


Antennaria dioica (mountain everlasting, stoloniferous pussytoes, catsfoot or cudweed) is a Eurasian and North American species of flowering plant in the family Asteraceae. It is a perennial herb found in cool northern and mountainous regions of Europe and northern Asia (Russia, Mongolia, Japan, Kazakhstan, China (Xinjiang, Heilongjiang, Gansu)), and also in North America in Alaska only.


Antennaria dioica is an evergreen, herbaceous perennial plant growing to 10–20 cm tall, with a rosette of basal spoon-shaped leaves 4 cm long, and 1 cm broad at their broadest near the apex; and smaller leaves arranged spirally up the flowering stems. The flowers are produced in capitula (flowerheads) 6–12 mm diameter with pale pink ray florets and darker pink disc florets. The plant's common name is derived from the flower clusters which are thought to resemble the pads or toes of a cat's paw.
It is dioecious, but can also reproduce without fertilisation. It is found in groups which can be all-female colonies, all-male colonies, and also mixed colonies. The male plants have whiter flower heads than female plants. The species name, dioica, is derived from Greek as reference to the separate male and female plants. Its common habitats include mountain grasslands, dry pastures and woodland edges.


While not widely used in herbal medicine, the plant was believed to have antitussive, astringent, diuretic and emollient properties. It has been traditionally used to treat bronchitis, liver and gall bladder complaints, hepatitis and diarrhea. Externally, it has been used as a gargle for treating tonsillitis and as a douche for vaginitis.
John Gerard's Herball (1597) describes the plant: "When the flower hath long flourished and is waxen old, then comes there in the middest of the floure a certain brown yellow thrumme, such as is in the middest of the daisie, which floure being gathered when it is young may be kept in such manner (I meane in such freshness and well-liking) by the space of a whole year after in your chest or elsewhere, wherefore our English women have called it 'Live Long,' or 'Live-for ever,' which name doth aptly answer this effects."


Anthidium oblongatum, the oblong woolcarder bee, is a species of bee in the family Megachilidae, the leaf-cutter, carder, or mason bees.


Reported from Morocco in North Africa. In Eurasia from Portugal via southern, central and eastern Europe, Ukraine, southern Russia and Siberia (east to Tuva) as well as via Asia Minor, the Caucasus to the Central Asian mountains and, if the information from Wu (2006) applies, to Inner Mongolia ; in Europe northwards to the Netherlands, Brandenburg, central Poland and Belarus; south to Sicily (not in Corsica and Sardinia), Thessaly (not in Crete and Cyprus), Iran and Afghanistan. Introduced in the eastern United States.


The flight period is in one generation from mid-June to early August.
A. oblongatum uses cavities to create the nest. Wherever 5–6 mm wide, horizontal crevices are available (dry stone walls, slatey, weathered rocks), these are preferred to be populated. But other cavities also serve as nesting places, for example passage-like cavities in the house, which are also used by Anthidium manicatum. The brood cells are made from vegetable wool. The species populates gardens, especially those that also have suitable food plants and sources of building material. A. oblongatum dabs the outside of the nest with rust-colored glandular secretions. A. oblongatum is found almost exclusively on Fabaceae, especially on Lotus spec. or Onobrychis spec., on Crassulaceae, especially Sempervivum spec. and Sedum spec. or on Resedaceae collecting pollen.  Lotus corniculatus, Onobrychis viciifolia and Sedum reflexum are preferred.
Parasites: In France, Stelis punctulatissima was raised from a nest of A. oblongatum. Another breeding parasite, according to observations from Germany and Switzerland, is very likely to be Chrysis marginata.


From Latin "oblongatum" = "elongated, elongated"; Illiger does not provide any information on choosing the name.


The red wattlebird (Anthochaera carunculata) is a passerine bird native to southern Australia. At 33–37 cm (13–14+1⁄2 in) in length, it is the second largest species of Australian honeyeater. It has mainly  grey-brown plumage, with red eyes, distinctive pinkish-red wattles on either side of the neck, white streaks on the chest and a large bright yellow patch on the lower belly. The sexes are similar in plumage. Juveniles have less prominent wattles and browner eyes. John White described the red wattlebird in 1790. Three subspecies are recognized.
The species is found in southeast Queensland, New South Wales, Victoria, South Australia and southwest Western Australia in open forest and woodlands, and is a common visitor to urban gardens and parks. Loud and conspicuous, the red wattlebird is generally found in trees, where it gets most of its food; occasionally it forages on the ground. It is one of the largest nectarivorous birds in the world, feeding from a wide variety of flowering plants. Insects also comprise part of its diet. It is territorial and at times aggressive towards birds of other species, often defending rich sources of nectar. Breeding throughout its range, the red wattlebird builds a cup-shaped nest in a tree and raises one or two broods a year. Although it has declined in places from land-clearing, it is classified as Least Concern on the IUCN Red List.


The red wattlebird was first described as the wattled bee-eater by the Irish surgeon and naturalist John White in his Journal of a Voyage to New South Wales, which was published in 1790. He wrote that it was the "size of a missel thrush, but much larger in proportion". The taxonomic descriptions in White's book are believed to have been written by the English naturalist George Shaw, who is generally credited as the author by subsequent authorities. The specific epithet, carunculata, was introduced later in the same year by John Latham. The word is derived from caruncula, Latin for 'a small piece of flesh'. Both Shaw and Latham assigned the red wattlebird to the genus Merops. The species was moved to Anthochaera in 1827 by the naturalists Nicholas Aylward Vigors and Thomas Horsfield. The generic name derives from the Ancient Greek anthos 'flower, bloom' and khairō 'enjoy'.
Common names include gillbird, gilly warbler, barkingbird, muttonbird, butcherbird, what's o clock, and chock. Unlike many species in southwestern Australia, the red wattlebird was given names by the local indigenous people that were onomatopoeic (sounding like the calls they make). Names recorded include wodjalok, durdal, doongorok, and djoongong (this last name is also applied to the western wattlebird). In the Eyre Peninsula in South Australia, the local Barngarla people knew it as ngarkarko or ngarkabukko. The local people of Denial Bay in South Australia called it noggal, and the Ngarrindjeri people of the Lower Murray region in South Australia knew it as rungkan.
There are three recognised subspecies, though there is a zone of intermediate birds across western Victoria and eastern South Australia, bordered by western Port Phillip Bay to the east, Mount Lofty Ranges to the west, and Little and Big Desert national parks to the north. The differences in plumage are not generally prominent enough to be noticeable in the field.
A. c. carunculata (Shaw, 1790) – found in southeast Australia, namely Victoria, eastern New South Wales, and southeastern Queensland.
A. c. clelandi (Mathews, 1923) – Kangaroo Island (South Australia). Of a similar size to the nominate subspecies, it tends to have darker plumage, a longer bill, and shorter tarsus.
A. c. woodwardi Mathews, 1912 – southwest and south-central Australia, west of the Mount Lofty Ranges. This subspecies is a little smaller than the nominate subspecies and has shorter wings. Its plumage is similar, though the yellow patch on the belly is more prominent.
Analysis of DNA showed that the closest relative of the red wattlebird is the yellow wattlebird of Tasmania, the pair splitting from the ancestor of the regent honeyeater—their next closest relative. Honeyeaters are related to the Pardalotidae (pardalotes), Acanthizidae (Australian warblers, scrubwrens, thornbills, etc.), and Maluridae (Australian fairy-wrens) in the large superfamily Meliphagoidea.


The sexes of the red wattlebird are similar in size and plumage, the length of the adult male ranging from 33 to 37 centimetres (13 to 15 in) and the adult female from 34 to 37 centimetres (13 to 15 in). With an average weight of 100–120 grams (3.5–4.2 oz), the red wattlebird is one of the largest nectar-feeding birds in the world, and the second largest species of honeyeater native to Australia, eclipsed only by the yellow wattlebird. The crown, forehead and upper lores (area between the eyes and nostrils) are dark brown, streaked with pale brown at the front of the crown and white at the rear of the crown. The nape (back of the neck) is slightly paler brown, with white streaks. A whitish triangular marking covers the lower lores and anterior ear covert feathers, bordered below by a dark brown stripe from the lower mandible down to the wattle and around to behind the eye. The throat is dark brown streaked with white. The iris of the eye is orange-red to crimson. The distinctive pinkish-red wattles dangle from the lower rear corner of the ear coverts on either side of the neck, and there is a sliver of pink bare skin at the lower border of the white patch on the face. The chest and belly are streaked white, and there is a bright yellow patch towards the tail. The strong legs and feet are pink or pinkish-brown, and the downward-curving bill is black. The average dimensions of the bill are 23.5 millimetres (0.93 in) long, 6.7 millimetres (0.26 in) wide, and 6.8 millimetres (0.27 in) high at its base. The gape is grey-black, while the inside of the mouth is orange. In common with other honeyeaters, the red wattlebird has a long, specialized tongue to extract nectar from flowers. The tongue can extend well beyond the tip of the bill, and is divided at the end to form a brush-like structure with over a hundred bristles that soak up nectar by capillary action.
The red wattlebird begins moulting after the breeding season, starting with the primary flight feathers in November or December, and finishing between the following March and May. The feathers of the breast, back, median and lesser covert feathers are moulted before those of the crown, remiges, and rectrices.
Immature red wattlebirds are generally less flamboyant. Juveniles have much less prominent wattles, brown irises, a pale crown, and much less yellow on the belly. They moult into first immature plumage within a few months of leaving the nest. First immature birds are more similar to adults overall, having red irises with brown rings, wattles larger but still smaller than adults, and a greyish pink gape.
The red wattlebird is hard to confuse with any other species, though in poor visibility it might be mistaken for the spiny-cheeked honeyeater, or little or western wattlebirds.


Red wattlebirds are noisy animals, producing a range of raucous calls. Pairs of birds appear to duet, particularly at food sources, with the male producing a loud cackle and the female a whistling call. The male's cackle is loudest between 1 and 3 kHz frequency. A guttural-sounding call, it has been variously described as having a squawking, coughing or hiccuping sound. Males cackle when foraging by themselves, when with other birds, or when declaring their territory to other birds. The whistling call consists of up to five rapid whistles that may or may not ascend in tone, and are repeated 3–4 times. Both sexes commonly utter a single chock note that may be harsh and guttural or have 4–5 harmonics. This is thought to be a contact call. These calls all carry over long distances.
Red wattlebirds utter two types of alarm calls, alternating between them while mobbing other animals. One is a harsh call over a wide frequency (1.3 to 5.9 kHz) that is louder at lower frequencies. The other is a lower-pitched staccato call with a frequency of 1.1–2.2 kHz. They give a harsh call when trying to distract intruders from the vicinity of the nest or when picked up, often trying to flap or peck the handler.


The red wattlebird is found in southeast Queensland, where it occurs south of Noosa and Cooloola, becoming more common south of Brisbane and Toowoomba. Further south into New South Wales it is found most places east of (and including) the Great Dividing Range and stretching west to the southern North-West Plain, Central Western Slopes and eastern Riverina, and is an occasional visitor to points along the Murray River valley. It is found across Victoria, though is uncommon in the northwest of the state. In South Australia, Devonborough Downs Station, Manunda, Wilpena Pound and Nullarbor Station mark the northern limits of its range. There are scattered records from the Nullarbor Plain, but the species is common in Western Australia west of  125 °E and south of 29 °S. The yellow wattlebird replaces it in Tasmania. The red wattlebird has become more common in some localities, such as the Sunraysia district in the 1960s, and Nambucca Heads and Lefevre Peninsula in the 1980s. Breeding numbers have increased in Sydney and Adelaide. The red wattlebird is a rare vagrant to New Zealand, with confirmed records at Matakana in 1865 and Rohutu, Taranaki, in 1885, and a third unconfirmed report from Motupiko in 1938.
The red wattlebird appears to be a permanent resident in much of its range, though its movements are poorly known. It appears to be partly migratory in Western Australia and the north coast of New South Wales. In southeastern New South Wales and the Australian Capital Territory, it appears to move to lower altitudes for winter. For instance, birds vacate the Brindabella Range over the cooler months. Overall, little pattern is discernible in the species' movements, though red wattlebirds appear to move to feed on populations of flowering banksias and eucalypts, such as winter-flowering banksias in Perth over the cooler months. Large numbers arrive in  time to feed on flowering native apples (Angophora) in Mudgee and Cobbora districts in central-western New South Wales, and on white box (Eucalyptus albens) at Barrington in central-northern New South Wales. A mainly resident population on the Swan Coastal Plain near Perth is supplemented during winter by more arriving from inland areas. South of Perth, red wattlebirds are more locally nomadic, moving to new patches of blooming wildflowers. East of Perth in areas around Kellerberin, Kwolyin, and Nangeenan, the red wattlebird is present from late autumn to spring, breeding in August and September. Around Lake Grace, the red wattlebird is present year-round.
Open sclerophyll forest and woodland, generally dominated by eucalypts, is the most common habitat of the species. It is more common in forests with ample shrubby or grassy understory. It is less commonly encountered in shrubland, heath, or margins of wet sclerophyll forest. It is rarely found in mature pine plantations. Within urban areas, it is abundant in parks and reserves, gardens and golf courses, as well as orchards and vineyards. It occasionally ventures into subtropical, semi-arid or subalpine regions, and has been found up to 1,900 m (6,000 ft) above sea level. The red wattlebird is rarer in forests that have been affected by dieback (infection by the pathogen Phytophthora cinnamomi).


A loud and active bird, the red wattlebird is found in pairs, in a small family group, or alone during the breeding season, and gathers in larger groups of up to several hundred birds over winter. It flies straight or with a slightly undulating pattern, alternating between gliding and flapping its wings with quick shallow beats, at or slightly above the level of the tree canopy. The red wattlebird moves on the ground by hopping, cocking its tail upwards slightly.
Aggressive and territorial, the red wattlebird defends its nest and sources of food against other birds. It either calls at, snaps at the tails of, or flies at other birds, sometimes scuffling with members of the same species or other large honeyeaters in the air. Displacement is a dominant display in which a red wattlebird will land on a perch that has been immediately vacated by another bird. A smaller red wattlebird adopts a horizontal appeasement posture side-on to the aggressor in which it lowers its head, flutters its wings and edges closer to the other bird.
As well as smaller bird species, red wattlebirds can mob and chase larger species, such as the Australian magpie (Gymnorhina tibicen), butcherbirds, currawongs, the black-faced cuckooshrike (Coracina novaehollandiae), the olive-backed oriole (Oriolus sagittatus), crows, ravens, the laughing kookaburra (Dacelo novaeguineae), and even small raptors like the collared sparrowhawk (Accipiter cirrocephalus).


The red wattlebird breeds throughout its range, with nesting taking place between July and December, though occasionally outside these months, if conditions are favourable. One or two broods are laid each year.
Red wattlebirds generally nest as solitary pairs. The nest is a cup-shaped structure formed from sticks and leaves, lined with bark, grass, and hair, between 2 and 16 metres (7 and 50 ft) above ground, usually in the forked branches of a tree—generally a eucalypt. The nest is usually located centrally rather than on the periphery of a tree. A study in Eastwood State Forest, near Armidale in New South Wales, found that red wattlebirds preferred to nest in manna gum (Eucalyptus viminalis) and apple box (E. bridgesiana).
A clutch of two or three pale brown- and lavender-spotted pinkish eggs are normally laid. They measure 33 mm × 22 mm (1+1⁄4 in × 7⁄8 in), and are a tapered oval in shape. The eggs are normally incubated by both parents, but sometimes just by the female. They hatch after 16–21 days. The chicks are born almost naked, with a small amount of grey down on their head and body. They are mostly brooded by the female, but sometimes the male will also brood. The nestlings are fed by both parents, and occasionally immature birds will contribute. Their eyes open at around 7 days. They fledge 15–20 days after hatching, and both parents continue to feed them for a further 2–3 weeks. Young are given manna (crystallised plant sap) and insects, such as beetles, bugs, and flies.
