Bokikokiko
The bokikokiko, Kiritimati reed warbler or Christmas Island warbler (''Acrocephalus aequinoctialis'') is a species of warbler in the family Acrocephalidae. It is found only on Kiritimati and Washington Island (Kiribati). The population size of the bokikokiko is estimated to be around 2500, with a decreasing population trend. The species is under threat from introduced species such as the pig and rat but especially the feral cat and climate change in relation to rising sea levels. This species, along with the Henderson petrel, is currently listed as endangered on the IUCN Red List. Subspecies The species may be divided into the following subspecies: *''Acrocephalus aequinoctialis aequinoctialis'' Latham, 1790. (Distributed across northern pacific Line Islands.) * ''Acrocephalus aequinoctialis pistor.'' (Distributed across Teraina and Tabuaeran.) Human Interactions This bird has a lot of medicinal and symbolic significance. Its feathers are considered to have testosterone ...

Acrocephalidae
The Acrocephalidae (the reed warblers, marsh- and tree-warblers, or acrocephalid warblers) are a family of oscine passerine birds, in the superfamily Sylvioidea. The species in this family are usually rather large "warblers". Most are rather plain olivaceous brown above with much yellow to beige below. They are usually found in open woodland, reedbeds, or tall grass. The family occurs mostly in southern to western Eurasia and surroundings, but also ranges far into the Pacific, with some species in Africa. Genus '' Acrocephalus'' Marsh-warblers. About 43 species; para- or polyphyletic. * Moustached warbler, ''Acrocephalus melanopogon'' * Aquatic warbler, ''Acrocephalus paludicola'' * Sedge warbler, ''Acrocephalus schoenobaenus'' * Speckled reed warbler, ''Acrocephalus sorghophilus'' * Black-browed reed warbler, ''Acrocephalus bistrigiceps'' * Paddyfield warbler, ''Acrocephalus agricola'' * Manchurian reed warbler, ''Acrocephalus tangorum'' * Blunt-winged warbler, ''Acrocep ...

Kiribati
Kiribati, officially the Republic of Kiribati, is an island country in the Micronesia subregion of Oceania in the central Pacific Ocean. Its permanent population is over 119,000 as of the 2020 census, and more than half live on Tarawa. The state comprises list of islands of Kiribati, 32 atolls and one remote raised coral atoll, raised coral island, Banaba. Its total land area is dispersed over of ocean. The islands' spread straddles the equator and the 180th meridian. The International Date Line goes around Kiribati and swings far to the east, almost reaching 150th meridian west, 150°W. This brings Kiribati's easternmost islands, the southern Line Islands south of Hawaii, into the same day as the Gilbert Islands and places them in the most advanced time zone on Earth: UTC+14:00, UTC+14. Kiribati gained its independence from the United Kingdom, becoming a sovereign state in 1979. The capital, South Tarawa, now the most populated area, consists of a number of islets, connect ...

Acrocephalus (bird)
The ''Acrocephalus'' warblers are small, insectivorous passerine birds belonging to the genus ''Acrocephalus''. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and Eurasian reed warbler, reed warbler. These are rather drab brownish warblers usually associated with marshes or other wetlands. Some are streaked, others plain. Many species breeding in temperate regions are bird migration, migratory. This genus has heavily diversified into many species throughout islands across the tropical Pacific Ocean, Pacific. This in turn has led to many of the resulting insular Endemism, endemic species to become Endangered species, endangered. Several of these species (including all but one of the species endemic to the Mariana Islands, Marianas and two endemic to French Polynesia) have al ...

John Latham (ornithologist)
John Latham (27 June 1740 – 4 February 1837) was an English physician, natural history, naturalist and author. His main works were ''A General Synopsis of Birds'' (1781–1801) and ''A General History of Birds'' (1821–1828). He was able to examine specimens of Australian birds that reached England in the final twenty years of the 18th century, and was responsible for providing English names for many of them. He named some of Australia's most famous birds, including the emu, sulphur-crested cockatoo, wedge-tailed eagle, superb lyrebird, Australian magpie, magpie-lark, white-throated needletail and pheasant coucal. Latham has been called the "grandfather" of Australian ornithology. He was also the first to describe the hyacinth macaw from South America. Biography John Latham was born on 27 June 1740 at Eltham in northwest Kent. He was the eldest son of John Latham (died 1788), a surgeon, and his mother, who was a descendant of the Sothebys, in Yorkshire. He was educated at Merc ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Endemic Fauna Of Kiribati
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Birds Of Micronesia
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further ...

Hunting
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...

Testosterone
Testosterone is the primary male sex hormone and androgen in Male, males. In humans, testosterone plays a key role in the development of Male reproductive system, male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of androgenic hair, body hair. It is associated with increased aggression, sex drive, Dominance hierarchy, dominance, courtship display, and a wide range of behavioral characteristics. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behavior, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.

Feathers
Feathers are epidermis (zoology), epidermal growths that form a distinctive outer covering, or plumage, on both Bird, avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and an example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant Aves, birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and crypsis, protection. The study of feathers is called plumology (or plumage science). People use feathers in many ways that are practical, cultural, and religious. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henderson Petrel
The Henderson petrel (''Pterodroma atrata'') is a ground-nesting species of gadfly petrel in the family Procellariidae. Adults measure on average 37 cm. It has a uniform grey-brown plumage. These birds are endangered. It is found in the Pitcairn Islands, and possibly in French Polynesia, though confusion over the taxon makes reports of this species in the Marquesas, Tuamotus, Australs and Gambiers uncertain. Breeding colonies formerly existed on Ducie Island, but were wiped out by invasive rats by 1922. It is now believed to nest uniquely on Henderson island, which was declared a World Heritage Site in 1988. The International Union for Conservation of Nature classifies it as closely related to ''Pterodroma arminjoniana'' and ''Pterodroma heraldica''. Its natural habitat is the moist subtropical scrub found on that island. The endangered habitat of this species was identified in 2007 as requiring urgent action to restore it. During Captain Cook's first voyage, Daniel Sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.
