Fauna Of The Cocos (Keeling) Islands
The terrestrial fauna of the Cocos (Keeling) Islands is unsurprisingly depauperate, because of the small land area of the islands, their lack of diverse habitats, and their isolation from large land-masses. However, the fauna dependent on marine resources is much richer. Birds As a small and isolated group of islands in two atolls apart in the eastern Indian Ocean, the number of species of resident landbirds (as opposed to seabirds and waders) is very small. These comprise the endemism, endemic subspecies of buff-banded rail, the introduced green junglefowl and helmeted guineafowl, the white-breasted waterhen, eastern reef egret, nankeen night heron and the introduced Christmas white-eye. Four other introduced species are now extinct in the Islands. Several other landbird species have been recorded occasionally, but none has established a breeding population. Migratory waders recorded in the islands include some regular visitors as well as vagrants. None breeds there. Howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christmas White-eye
The Christmas white-eye (''Zosterops natalis'') is a species of bird in the family Zosteropidae. It is endemic to Christmas Island. Its natural habitats are tropical and subtropical moist broadleaf forests and subtropical or tropical moist shrubland. It is threatened by habitat destruction. Description The Christmas white-eye has a length of between . The upper parts are greyish-olive and the underparts whitish. There is a yellowish streak above the eye and a distinctive white feather ring surrounding the eye. Distribution and habitat The genus ''Zosterops'' is an island specialist, with 82 of the 98 species being restricted to islands, and many species being known from only a single island. It is a highly successful group, having an unspecialised diet and a great dispersal capacity. The Christmas white-eye is endemic to Christmas Island, but it has also been successfully introduced to the Cocos (Keeling) Islands where it has become established, but mostly around human settlemen ...

Herald Petrel
The Herald petrel (''Pterodroma heraldica'') is a species of seabird and a member of the gadfly petrels. Its range includes the south Pacific Ocean and Indian Ocean. Description The bird is in size, with an wingspan. It was formerly considered conspecific with the Trindade petrel and Henderson petrel. This petrel has various colour morphs: dark and light, as well as intermediates between the two. Habitat and range The Herald petrel nests on oceanic islands and atolls, on cliff ledges, ridges or rocky slopes. On some islands, nesting birds are threatened by feral cats and rats. Found primarily in the south Pacific, it has been seen in Hawaii. In May 2007, a Herald petrel tagged on Raine Island in 1984 was observed off the coast of Mauritius in the Indian Ocean. This greatly increases the known life span and range of the species. In 2009 it was identified as this species, from what was previously an unidentified ''Pterodroma'' species, to be breeding on Round Island, nort ...

Sooty Tern
The sooty tern (''Onychoprion fuscatus'') is a seabird in the family Laridae. It is a bird of the tropical oceans, returning to land only to breed on islands throughout the equatorial zone. Taxonomy The sooty tern was described by Carl Linnaeus in 1766 as ''Sterna fuscata'', bearing this name for many years until the genus ''Sterna'' was split up. It is now known as ''Onychoprion fuscatus''. The genus name is from ancient Greek , "claw" or "nail", and , "saw". The specific ''fuscatus'' is Latin for "dark". Colloquially, it is known as the wideawake tern or just wideawake. This refers to the incessant calls produced by a colony of these birds, as does the Hawaiian name ''ʻewa ʻewa'' which roughly means "cacophony". In most of Polynesia its name is ''manutara'' or similar – literally "tern-bird", though it might be better rendered in English as "the tern" or "common tern". This refers to the fact that wherever Polynesian seafarers went on their long voyages, they usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-tailed Tropicbird
The white-tailed tropicbird (''Phaethon lepturus'') is a tropicbird. It is the smallest of three closely related seabirds of the tropical oceans and smallest member of the order Phaethontiformes. It is found in the tropical Atlantic, western Pacific and Indian Oceans. It also breeds on some Caribbean islands, and a few pairs have started nesting recently on Little Tobago, joining the red-billed tropicbird colony. In addition to the tropical Atlantic, it nests as far north as Bermuda, where it is locally called a "longtail". Taxonomy There are six subspecies: * ''P. l. lepturus''—Indian Ocean * ''P. l. fulvus'' (golden bosun)—This form has a golden wash to the white plumage * ''P. l. dorotheae''—tropical Pacific * ''P. l. catesbyi''—Bermuda and Caribbean * ''P. l. ascensionis''— Ascension Island * ''P. l. europae''—Europa Island, s. Mozambique Channel Description The adult white-tailed tropicbird is a slender, mainly white bird, 71–80 cm long including the ...

Red-tailed Tropicbird
The red-tailed tropicbird (''Phaethon rubricauda'') is a seabird native to tropical parts of the Indian and Pacific Oceans. One of three closely related species of tropicbird (Phaethontidae), it was described by Pieter Boddaert in 1783. Superficially resembling a tern in appearance, it has almost all-white plumage with a black mask and a red bill. The sexes have similar plumage. As referenced in the common name, adults have red that are about twice their body length. Four subspecies are recognised, but there is evidence of clinal variation in body size—with smaller birds in the north and larger in the south—and hence no grounds for subspecies. The red-tailed tropicbird eats fish—mainly flying fish and squid—after catching them by plunge-diving into the ocean. Nesting takes place in loose colonies on oceanic islands; the nest itself is a scrape found on a cliff face, in a crevice, or on a sandy beach. A single egg is laid, then is incubated by both sexes for about six ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Booby
The brown booby (''Sula leucogaster'') is a large seabird of the booby family Sulidae, of which it is perhaps the most common and widespread species. It has a pantropical range, which overlaps with that of other booby species. The gregarious brown booby commutes and forages at low height over inshore waters. Flocks plunge-dive to take small fish, especially when these are driven near the surface by their predators. They only nest on the ground, and roost on solid objects rather than the water surface. Taxonomy The brown booby was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his ''Histoire Naturelle des Oiseaux'' in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch naturalist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masked Booby
The masked booby (''Sula dactylatra''), also called the masked gannet or the blue-faced booby, is a large seabird of the booby and gannet family, Sulidae. First described by the French naturalist René-Primevère Lesson in 1831, the masked booby is one of six species of booby in the genus '' Sula''. It has a typical sulid body shape, with a long pointed yellowish bill, long neck, aerodynamic body, long slender wings and pointed tail. The adult is bright white with black wings, a black tail and a dark face mask; at long, it is the largest species of booby. The sexes have similar plumage. This species ranges across tropical oceans, except in the eastern Atlantic and eastern Pacific. In the latter, it is replaced by the Nazca booby (''Sula granti''), which was formerly regarded as a subspecies of masked booby. Nesting takes place in colonies, generally on islands and atolls far from the mainland and close to deep water required for foraging. Territorial when breeding, the masked ...

Wedge-tailed Shearwater
The wedge-tailed shearwater (''Ardenna pacifica'') is a medium-large shearwater in the seabird family Procellariidae. It is one of the shearwater species that is sometimes referred to as a muttonbird, like the sooty shearwater of New Zealand and the short-tailed shearwater of Australia. It ranges throughout the tropical Pacific and Indian Oceans, roughly between latitudes 35°N and 35°S. It breeds on islands off Japan, on the Islas Revillagigedo, the Hawaiian Islands, the Seychelles, the Northern Mariana Islands, and off Eastern and Western Australia. Taxonomy The wedge-tailed shearwater was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria pacifica''. Gmelin based his description on the "Pacific petrel" that had been described in 1785 by the English ornithologist John Latham i ...

White Tern
The white tern or common white tern (''Gygis alba'') is a small seabird found across the tropical oceans of the world. It is sometimes known as the fairy tern, although this name is potentially confusing as it is also the common name of '' Sternula nereis''. Other names for the species include angel tern and white noddy in English, and manu-o-Kū in Hawaiian. The little white tern ('' Gygis microrhyncha''), previously considered a subspecies of the white tern (''Gygis alba microrhyncha''), is now recognised as a separate species. Taxonomy The white tern was first formally described by the Swedish naturalist Anders Sparrman in 1786 under the binomial name ''Sterna alba''. The genus ''Gygis'' was introduced by the German zoologist Johann Georg Wagler in 1832. The name ''Gygis'' is from the Ancient Greek for a mythical bird and the specific is Latin for "white". Molecular phylogenetic studies have shown that the white tern is more closely related to the noddies than it is to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Noddy
The brown noddy or common noddy (''Anous stolidus'') is a seabird in the family Laridae. The largest of the noddies, it can be told from the closely related black noddy by its larger size and plumage, which is dark brown rather than black. The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. The brown noddy is colonial, usually nesting on elevated situations on cliffs or in short trees or shrubs. It only occasionally nests on the ground. A single egg is laid by the female of a pair each breeding season. In India, the brown noddy is protected in the PM Sayeed Marine Birds Conservation Reserve. Taxonomy The first formal description of the brown noddy was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' ...

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 one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
