pelagic cormorant range

& Williams, J.C. (2004): Cormorant surveys in the Near Island Group, Aleutian Islands, Alaska in July 2003 with notes on other species. Pelagic Cormorant (Phalacrocorax pelagicus) is a species of bird in the Phalacrocoracidae family. Dark glossy-green cormorant with a bluish neck, red face, and yellowish bill. [17], However, a subsequent analysis of a larger number of comparison specimens of the pelagic cormorant – mainly from birds that fell victim to the Exxon Valdez oil spill – determined that the bones were attributable to small females of the latter species, and that their apparent distinctness was due to the original canonical analysis being distorted by insufficient specimens. The supposed "cliff shag" subfamily Leucocarboninae is entirely paraphyletic cannot be accepted as originally circumscribed. Discussion. Nests are usually conpact and saucer shape, and guano acts as a cement to hold it together and to the cliff. The specific name kenyoni honors USFWS biologist Karl W. Kenyon, who collected the type specimen USNM 431164 on 22 February 1959. Cormorants dive underwater and use their large webbed feet as paddles to swim in search of food. In normal years, all young of a typical clutch may be raised successfully, but less than four rarely fledge. If the Aleutian population were to be considered a distinct subspecies, the name kenyoni would apply. Breeds along the Pacific Coast of North America from the western Alaska and the Aleutian archipelago south to extreme southern California. It relies on flight to move around. In Washington, significant increases in the population were recorded between 1976 and 1992. The pelagic cormorant's range extends from the Chukchi and Bering Seas south along the North American Pacific coast to Baja California, and along the Asian coast to southern China. The Pelagic Cormorant inhabits the shores and the neritic zone of the North Pacific. [9], This numerous and widespread species is not considered threatened by the IUCN. The Pelagic Cormorant uses its own guano to solidify its nest materials and to cement its nest to the cliff face. They eat a wide variety of foods, but fish that live close to the ocean floor are their favorites. [13], Its traditional scientific name is the literal Latinized Ancient Greek equivalent of the common name: Phalacrocorax is an ancient term for cormorants; literally, it means "bald raven", from falakrós (φᾶλακρός, "bald") + kórax[14] (κόραξ, "raven"). Avibase is an extensive database information system about all birds of the world, containing over &1 million records about 10,000 species and 22,000 subspecies of birds, including distribution information for 20,000 regions, taxonomy, synonyms in several languages and more. The Red-faced Cormorant lives in the southern regions of Alaska out into the Aleutian Islands. The bulk of its population is found in the relatively inaccessible waters of the Bering Sea region; about 50,000 each breed in the Kuril Islands, the Bering Sea islands, and the U.S. state of Alaska and its offshore islands (including the Aleuts). It … The Pelagic Cormorant feeds mainly on nonschooling medium sized fish, but also consumes invertebrates, maine worms and crustaceans. They prefer to forage near kelp beds or among rocks. Pelagic Cormorant Annual Range. The Brandt's cormorant is a seabird found only in North America with a range along the coast from Alaska to Mexico. The pelagic cormorant breeds from the Bering Sea south to northern Baja California. This is a North Pacific clade, which apart from Brandt's and the pelagic cormorant also includes the red-faced cormorant (P. urile) and probably also the extinct spectacled cormorant (P. perspicillatus). Among the Compsohalieus group, the red-faced cormorant is the sister species of P. pelagicus. The neotropic cormorant lives in coastal Texas, and the red-faced cormorant, pelagic cormorant, and Brandt’s cormorant reside on the west coast of the US. Pelagic cormorants forage only during the day and usually alone in sheltered bays and inlets. The measurements of 40 eggs, in various collections, average 61.7 by 40.4 millimeters; the eggs showing the four extremes measure 65 by 40 and 51 by 36 millimeters. [16], Two subspecies are generally recognized. They nest along with other cormorants and other seabirds on steep, remote cliffs where they're safer from predators. Pelagic cormorants live along open, windswept coasts. White patches on sides of rump. Similar to: Red-faced Cormorant. They can spring straight up out of the water into the air and fly. The subarctic populations are migratory, while the birds from temperate and subtropical regions only disperse locally after breeding, but even so Asian birds may reach China or Korea. [11], This species is here placed in the catch-all genus Phalacrocorax. Thus, the birds return to a safe place after foraging to preen and dry their feathers, typically adopting a spread-winged posture. Spends winters from southern Alaska south to Baja California. Red-faced Cormorant has a more orange face patch, although the patch is larger and more conspicuous. Nest sites are usually on narrow ledges on steep rocky cliffs. Habitat. These small, slender cormorants are found along the open coasts of the northern Pacific. Pelagic Cormorant (Phalacrocorax pelagicus) is a species of bird in the Phalacrocoracidae family. The Pelagic Cormorant inhabits the shores and the neritic zone of the North Pacific. Eggs: The eggs of the Baird cormorant are practically indistinguishable from those of tim pelagic cormorant, though, strangly enough, the eggs, of which I have measurements, average larger. Adults in nonbreeding plumage are all-black with a metallic iridescence. During the breeding season the skin under their eyes turns a vivid magenta. Range. 野鳥撮影・ ヒメウ Pelagic Cormorant - Duration: 1:00. ID: Smaller in size [Kenyon's Shag or Amchitka Cormorant (Phalacrocorax pelagicus kenyoni / Phalacrocorax kenyoni - Karl W. Kenyon, 1959)] - usually considered invalid. It winters south from southern Alaska. Analogous to other smallish cormorants, it is also called the pelagic shag occasionally. It furthermore is found on the Aleutian and other Bering Strait islands, and from the Russian Far East Chukchi Peninsula via Sakhalin south to Kamchatka, and ultimately Kyūshū (though not the rest of Japan). It was described from the bones of three individuals snared in fishing nets in the late 1950s at Constantine Harbor on Amchitka in the Aleutian Islands. Its North American range extends from Alaska to the Baja peninsula in Mexico. The nest is repaired and improved in each season if need be; it can thus grow up to 5 ft (1.5 m) deep.
