Endangered Birds
As of December 2019, the International Union for Conservation of Nature (IUCN) lists 460 endangered avian species. 4% of all evaluated avian species are listed as endangered. No subpopulations of birds have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction." An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered birds are listed separately. There are 683 avian species which are endangered or critically endangered. Additionally 53 avian species (0.48% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. W ...

Nesofregetta Fuliginosa
The Polynesian storm petrel (''Nesofregetta fuliginosa'') is a species of seabird in the family Oceanitidae. It is the only species placed in the genus ''Nesofregetta''. Markedly polymorphic, several subspecies were described, and light birds were even considered a species on their own (white-throated storm-petrel). Not even subspecies are generally accepted today, however. It is found in Chile, French Polynesia, Kiribati, New Caledonia, Vanuatu, possibly American Samoa, possibly Fiji, and possibly Samoa. Its natural habitats are open seas, rocky shores, and sandy shores. It is threatened by introduced predators in its nesting areas. Taxonomy The Polynesian storm petrel 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 other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria fuliginosa''. Gmelin based his description on t ...

Puffinus Bannermani
Bannerman's shearwater (''Puffinus bannermani'') is a seabird in the family Procellariidae formerly considered conspecific with Audubon's shearwater (''Puffinus lherminieri''). Range Little is known of this species other than that it breeds in the Volcano Islands in the Ogasawara Group to the southwest of Japan and doesn't seem to range far from this area. Population The species population size has not been estimated but is assessed to be decreasing. Diet and Habitat Not much is known about this species and more research is required to obtain an understanding of its ecology. Based on the ecology of closely related species, ''P. bannermani'' is thought likely to feed on fish, squid and cephalopods A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, an ..., by surface-seizing, underwater p ...

Pterodroma Sandwichensis
The Hawaiian petrel or ''uau'' (''Pterodroma sandwichensis'') is a large, dark grey-brown and white petrel that is endemic to Hawaii. Distribution The Hawaiian petrel was formerly found on all the main Hawaiian Islands except Niihau, but today it is mostly restricted to Haleakalā crater on Maui; smaller populations exist on Mauna Loa on the island of Hawaii, Waimea Canyon on the island of Kauai, Lānaihale on Lānai, and possibly Molokai. It is also reportedly seen on the Galapagos Islands. Behavior Feeding Their diet consists of 50–75% squid, and smaller percentages of fish and crustaceans. Breeding The birds nest in burrows or rock crevices. The breeding extends from March to October. The female lays one white egg. When the chick hatches, the parents go out to sea and feed during the day, and return only at night. They pass their food on to the chicks by means of regurgitation. The chicks are charcoal-gray colored and were considered a delicacy by early Hawaiians. Scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterodroma Madeira
Zino's petrel (''Pterodroma madeira'') or the freira, is a species of small seabird in the gadfly petrel genus, endemic to the island of Madeira. This long-winged petrel has a grey back and wings, with a dark "W" marking across the wings, and a grey upper tail. The undersides of the wings are blackish apart from a triangle of white at the front edge near the body, and the belly is white with grey flanks. It is very similar in appearance to the slightly larger Fea's petrel, and separating these two Macaronesian species at sea is very challenging. It was formerly considered to be a subspecies of the soft-plumaged petrel, ''P. mollis'', but they are not closely related, and Zino's was raised to the status of a species because of differences in morphology, calls, breeding behaviour and mitochondrial DNA. It is Europe's most endangered seabird, with breeding areas restricted to a few ledges high in the central mountains of Madeira. Zino's petrel nests in burrows which are visited only a ...

Pterodroma Incerta
The Atlantic petrel (''Pterodroma incerta'') is a gadfly petrel endemic to the South Atlantic Ocean. It breeds in enormous colonies on Tristan da Cunha and Gough Island, and ranges at sea from Brazil to Namibia, with most records at sea being to the west of the breeding islands, and along the subtropical convergence. Adults are about 43 cm long, powerful, large, stocky, dark in color with white belly. Their head can appear to be grey in worn plumage. Brown undercoating of wings and tail. These petrels can live on average of 15 years of age. Population trends Although the species exists in large numbers, the world population being estimated at around 5 million birds, it is listed as endangered by the IUCN. It is restricted to just two breeding islands and has declined historically due to exploitation for food. According to some studies, there are roughly 1.1 million mating pairs, but only about 25% of eggs survived. This is making their large population numbers decrease rapi ...

Pterodroma Hasitata
The black-capped petrel (''Pterodroma hasitata''), also known as the diablotín, is a small seabird native to the West Indies in the genus '' Pterodroma''. It is a long-winged petrel with a grey-brown back and wings, with a white nape and rump. Underparts are mainly white apart from a black cap (that in some individuals extends to cover the eye) and some dark underwing markings. It picks food items such as squid from the ocean surface. Description The black-capped petrel is large compared to other gadfly petrels, with a length of about 16 inches (40.5 cm) and 37 inches (94 cm) wingspan. The most similar species within its range is the Bermuda petrel, which is smaller and has a narrower white rump patch and an extensive gray cowl. The great shearwater is also superficially similar. The critically endangered or possibly extinct Jamaica petrel (''P. caribbaea'') was a related dark form. The local Spanish name, ''Diablotín'', means "little devil" because of its night-time habits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterodroma Cahow
The Bermuda petrel (''Pterodroma cahow'') is a gadfly petrel. Commonly known in Bermuda as the cahow, a name derived from its eerie cries, this nocturnal ground-nesting seabird is the national bird of Bermuda and can be found pictured on Bermudian currency. It is the second rarest seabird on the planet and a symbol of hope for nature conservation. They are known for their medium-sized body and long wings. The Bermuda petrel has a greyish-black crown and collar, dark grey upper-wings and tail, white upper-tail coverts and white under-wings edged with black, and the underparts are completely white. For 300 years, it was thought to be extinct. The dramatic rediscovery in 1951 of eighteen nesting pairs made this a "Lazarus species", that is, a species found to be alive after having been considered extinct. This has inspired a book and two documentary films. A national programme to preserve the bird and restore the species has helped increase its numbers, but scientists are still worki ...

Pterodroma Baraui
Barau's petrel (''Pterodroma baraui'') is a medium-sized gadfly petrel from the family Procellariidae. Its main breeding site is the island of Réunion in the Indian Ocean. Etymology The name commemorates Armand Barau, an agricultural engineer and ornithologist from the French territory of Réunion in the Indian Ocean. It is one of the most recently discovered species of seabird and was only described in 1964, although it was known to local people prior to that. Description Barau's petrel is around 40 cm long, and has white undersides and forehead. Its bill is black and its upper parts are dark, with a moderately distinct "M" pattern across the wings and back. Distribution and habitat Barau's petrel ranges across the Indian Ocean from Réunion to Western Australia and Indonesia. With the exception of a single nest found on the island of Rodrigues the bulk of the population is thought to nest on Réunion. Behaviour Feeding The petrels are highly pelagic at sea, preying ...

Pterodroma Atrata
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] |
Procellaria Westlandica
The Westland petrel (''Procellaria westlandica''), (Māori: ''tāiko''), also known as the Westland black petrel, is a moderately large seabird in the petrel family Procellariidae, that is endemic to New Zealand. Described by Robert Falla in 1946, it is a stocky bird weighing approximately , and is one of the largest of the burrowing petrels. It is a dark blackish-brown colour with black legs and feet. It has a pale yellow with a dark tip. This species spends most of its life at sea but returns to land to breed. When at sea, it ranges across areas of the Pacific and Tasman seas around the subtropical convergence and migrates east to South American waters during the non-breeding season. They are nocturnal and feed on fish, squid and crustaceans. This species is also known to be an opportunistic feeder, scavenging fish waste discarded by hoki fishers. The only known breeding colonies of the Westland petrel are in New Zealand, in a small area of forest-covered coastal foothil ...
