supports: Polynesia ( from "poly" "many" + "nsos" "island") is a subregion of Oceania, made up of over 1,000 islands scattered over the central and southern Pacific Ocean. 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 French Polynesia; this overseas collectivity of the French Republic is sometimes referred to as an overseas country. The island is located in the archipelago of the Society Islands 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 French Polynesia and accounting for 68.5 percent of its total population. The Pacific Ocean 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. The Society Islands 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." 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 . 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. 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 North America 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. French Polynesia  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 Pacific Ocean. Its total land area is . The Old World consists of Africa, Europe, 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).
