The Tahiti reed warbler ( Acrocephalus caffer ) is a songbird in the genus Acrocephalus . It used to be placed in the `` Old World warbler '' assemblage ( Sylviidae ) , but is now in the newly recognized marsh warbler family Acrocephalidae . It is endemic to the Tahiti Island . Most taxonomists regard Garrett ' s reed warbler and the Moorea reed warbler as distinct . They used to be considered subspecies . As a whole , the Tahiti reed warbler was classified as a vulnerable species by the IUCN . But new research has shown it to be rarer than it was believed . Consequently , it was uplisted to endangered status in 2008 . ___MASK83___ is an overseas collectivity of the French Republic ; " ( COM )", sometimes unofficially referred to as an overseas country ; " ( POM )". It is composed of 118 geographically dispersed islands and atolls stretching over an expanse of more than in the South ___MASK85___ . Its total land area is . Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae . The family held over 400 species in over 70 genera , and were the source of much taxonomic confusion . Two families were split out initially , the cisticolas into Cisticolidae and the kinglets into Regulidae . In the past ten years they have been the subject of much research and many species are now placed into other families , including the Acrocephalidae , Cettiidae , Phylloscopidae , and Megaluridae . In addition some species have been moved into existing families or have not yet had their placement fully resolved . A smaller family of warblers , together with some babblers formerly placed in the family Timaliidae and the parrotbills , are retained in a much smaller family Sylviidae . The Old World consists of Africa , ___MASK37___ , and Asia , regarded collectively as the part of the world known to Europeans before contact with the Americas . It is used in the context of , and contrast with , the New World ( Americas ). Polynesia ( from " poly " " many " + " nsos " " island ") is a subregion of Oceania , made up of over 1 , 000 islands scattered over the central and southern ___MASK85___ . The indigenous people who inhabit the islands of Polynesia are termed Polynesians and they share many similar traits including language family , culture , and beliefs . Historically , they were experienced sailors and used stars to navigate during the night . Tahiti is the largest island in the Windward group of ___MASK83___ ; this overseas collectivity of the French Republic is sometimes referred to as an overseas country . The island is located in the archipelago of the ___MASK63___ in the central Southern Pacific Ocean , and is divided into two parts : The bigger , northwestern part " Tahiti Nui " and the smaller , southeastern part " Tahiti Iti ". The island was formed from volcanic activity and is high and mountainous with surrounding coral reefs . The population is 183 , 645 inhabitants ( 2012 census ), making it the most populous island of ___MASK83___ and accounting for 68 . 5 percent of its total population . The ___MASK85___ is the largest of the Earth ' s oceanic divisions . It extends from the Arctic Ocean in the north to the Southern Ocean ( or , depending on definition , to Antarctica ) in the south and is bounded by Asia and Australia in the west and the Americas in the east . A kinglet , or crest , is a small bird in a group that is sometimes included in the Old World warblers , but is frequently placed in its own family , Regulidae , because of resemblance to titmice . " Regulidae " is derived from the Latin word " regulus " for " petty king " or prince , and refers to the coloured crowns of adult birds . This family has representatives in ___MASK21___ and Eurasia . There are seven species in this family ; one , the Madeira firecrest , " Regulus madeirensis ", was only recently split from common firecrest as a separate species . One species , the ruby - crowned kinglet , differs sufficiently in its voice and plumage to occasionally be afforded its own genus , " Corthylio ". Description . Kinglets are among the smallest of all passerines , ranging in size from and weighing ; the sexes are the same size . They have medium - length wings and tails , and small needle - like bills . The plumage is overall grey - green , offset by pale wingbars , and the tail tip is incised . Five species have a single stiff feather covering the nostrils , but in the ruby - crowned kinglet , this is replaced by several short , stiff bristles . Most kinglets have distinctive head markings , and the males possess a colourful crown patch . In the females , the crown is duller and yellower . The long feathers forming the central crown stripe can be erected ; they are inconspicuous most of the time , but are used in courtship and territorial displays when the raised crest is very striking . The ___MASK63___ includes a group of islands in the South Pacific Ocean . It is , politically and legally , part of French Polynesia . The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769 , supposedly in honour of the Royal Society , the sponsor of the first British scientific survey of the islands ; however , Cook , himself , stated in his journal that he called the islands " Society " " as they lay contiguous to one another ."
