Lesser Frigatebird
The lesser frigatebird (''Fregata ariel'') is a seabird of the frigatebird family Fregatidae. At around 75 cm (30 in) in length, it is the smallest species of frigatebird. It occurs over tropical and subtropical waters across the Indian and Pacific Oceans as well as off the Atlantic coast of Brazil. The lesser frigatebird is a lightly built seabird with brownish-black plumage, long narrow wings and a deeply forked tail. The male has a striking red gular sac which he inflates to attract a mate. The female is slightly larger than the male and has a white breast and belly. Frigatebirds feed on fish taken in flight from the ocean's surface (often flying fish), and sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food. Taxonomy The lesser frigatebird was first described as ''Atagen ariel'' by the English zoologist George Gray in 1845 from a specimen collected on Raine Island, Queensland, Australia. The lesser frigatebird is on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''. Gray described many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gular Skin
Gular skin (throat skin), in ornithology, is an area of featherless skin on birds that joins the lower mandible of the beak (or ''bill'') to the bird's neck. Other vertebrate taxa may have a comparable anatomical structure that is referred to as either a gular sac, throat sac, vocal sac or gular fold. In birds Gular skin can be very prominent, for example in members of the order Phalacrocoraciformes as well as in pelicans (which likely share a common ancestor). In many species, the gular skin forms a flap, or gular pouch, which is generally used to store fish and other prey while hunting. In cormorants, the gular skin is often colored, contrasting with the otherwise plain black or black-and-white appearance of the bird. This presumably serves some function in social signalling, since the colors become more pronounced in breeding adults. In frigatebirds, the gular skin (or gular sac or throat sac) is used dramatically. During courtship display, the male forces air into the sac ...

Fernando De Noronha
Fernando de Noronha () is an archipelago in the Atlantic Ocean, part of the State of Pernambuco, Brazil, and located off the Brazilian coast. It consists of 21 islands and islets, extending over an area of . Only the eponymous main island is inhabited; it has an area of and a population estimated at 3,101 in 2020. While the archipelago is relatively low-lying, there are parts stretching above in elevation. The islands are administratively unique in Brazil. They form a "state district" ( pt, distrito estadual) that is administered directly by the government of the state of Pernambuco (despite being closer to the state of Rio Grande do Norte). The state district's jurisdiction also includes the very remote Saint Peter and Saint Paul Archipelago, located northeast of Fernando de Noronha. Seventy percent of the islands' area was established in 1988 as a national marine park. In 2001, UNESCO designated it as a World Heritage Site because of its importance as a feeding ground f ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalu ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jarvis Island
Jarvis Island (; formerly known as Bunker Island or Bunker's Shoal) is an uninhabited coral island located in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. It is an unincorporated, unorganized territory of the United States, administered by the United States Fish and Wildlife Service of the United States Department of the Interior as part of the National Wildlife Refuge system. Unlike most coral atolls, the lagoon on Jarvis is wholly dry. Jarvis is one of the Line Islands and for statistical purposes is also grouped as one of the United States Minor Outlying Islands. Jarvis Island is the largest of three U.S. equatorial possessions, which include Baker Island and Howland Island. Geography and ecology While a few offshore anchorage spots are marked on maps, Jarvis island has no ports or harbors, and swift currents are a hazard. There is a boat landing area in the middle of the western shoreline near a crumbling day beacon, and another near the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howland And Baker Islands
Howland Island and Baker Island are two uninhabited U.S. atolls in the Equatorial Pacific that are located close to one another. Both islands are wildlife refuges, the larger of which is Howland Island. They are both part of the larger political territory of the United States Minor Outlying Islands and they are also both part of the larger geographic grouping of the Phoenix Islands. Each is a National Wildlife Refuge managed by a division of Interior, the U.S. Fish and Wildlife Service. On January 6, 2009, U.S. President George W. Bush included both islands to the Pacific Remote Islands Marine National Monument. The Howland-Baker exclusive economic zone (EEZ) is a 400 nautical-mile diameter area protected by the U.S. Coast Guard. The Howland-Baker EEZ has 425,700 km2; by comparison, California has 423,970 km2. Howland Island was the area that Amelia Earhart was trying to reach in 1937 when she disappeared. The islands are the only land masses in the world associate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Islands
The Line Islands, Teraina Islands or Equatorial Islands (in Gilbertese, ''Aono Raina'') are a chain of 11 atolls (with partly or fully enclosed lagoons) and coral islands (with a surrounding reef) in the central Pacific Ocean, south of the Hawaiian Islands. The island chain stretches northwest to southeast across , making it one of the longest island chains in the world. It lies at the geographic center of the Pacific Ocean (), near Starbuck Island. One of the atolls in the group, Kiritimati, has the largest land area of any atoll in the world. Of the 11 atolls, all of which were formed by volcanic activity, only the Kiritimati and Tabuaeran atolls and Teraina island have a permanent population (one of the reefs, Filippo Reef, is shown on some maps, but its existence is doubted). Eight of the atolls are parts of Kiribati. The remaining three— Jarvis Island, Kingman Reef (which is largely submerged), and Palmyra Atoll—are territories of the United States grouped with th ...

Phoenix Islands
The Phoenix Islands, or Rawaki, are a group of eight atolls and two submerged coral reefs that lie east of the Gilbert Islands and west of the Line Islands in the central Pacific Ocean, north of Samoa. They are part of the Republic of Kiribati. Their combined land area is . The only island of any commercial importance is Canton Island (also called Abariringa). The other islands are Enderbury, Rawaki (formerly Phoenix), Manra (formerly Sydney), Birnie, McKean, Nikumaroro (formerly Gardner), and Orona (formerly Hull). The Phoenix Islands Protected Area, established in 2008, is one of the world's largest protected areas, and is home to about 120 species of coral and more than 500 species of fish. All of the Phoenix Islands are uninhabited, except for a few families who live on Kanton Island. At various times in history, the Phoenix Islands have been considered to be part of the Gilberts Island group (which itself was sometimes known as the ''Kingsmill'' island group). Geog ...
