Little Black Cormorant
The little black cormorant (''Phalacrocorax sulcirostris'') is a member of the cormorant family of seabirds. It is common in smaller rivers and lakes throughout most areas of Australia and northern New Zealand, where it is known as the little black shag. It is around sixty centimetres long, and is all black with blue-green eyes. Taxonomy The little black cormorant was formally described in 1837 by the German born naturalist Johann Friedrich von Brandt. He placed it in the genus ''Carbo'' and coined the binomial name ''Carbo sulcirostris''. The species is now placed in the genus '' Phalacrocorax'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The genus name ''Phalacrocorax'' is the Latin word for a cormorant. The specific epithet ''sulcirostris'' combines the Latin ''sulcus'' meaning "furrow" with ''-rostris'' meaning "-billed". The species is monotypic: no subspecies are recognised. The common name in New Zealand is the little black shag. A mole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand King Shag
The New Zealand king shag (''Leucocarbo carunculatus''), also known as the rough-faced shag, king shag or kawau, is a rare bird endemic to New Zealand. Some taxonomic authorities, including the International Ornithologists' Union, place this species in the genus ''Leucocarbo''. Others place it in the genus ''Phalacrocorax''. Taxonomy The New Zealand king shag 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 in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus carunculatus''. Gmelin based his description on the "carunculated shag" that had been described in 1785 by the English ornithologist John Latham in his book ''A General Synopsis of Birds ''. Latham had based his description on a specimen in the Leverian Museum. The New Zealand king shag is now one of 16 species placed in the genus ''Leucocarbo'' that was introduced in 1856 by the French na ...

Bounty Shag
The Bounty shag (''Leucocarbo ranfurlyi''), also known as the Bounty Island shag, is a species of cormorant of the family Phalacrocoracidae. They are found only on the tiny and remote Subantarctic Bounty Islands, 670 km southeast of New Zealand. Its natural habitats are open seas and rocky shores. In 2005 618 individuals were counted (with roughly 410 mature ones) and the population seems to have remained stable since. Some taxonomic authorities, including the International Ornithologists' Union, place this species in the genus ''Leucocarbo''. Others place it in the genus '' Phalacrocorax''. Description Size; 71 cm. Large, black-and-white cormorant. Black head, hind neck, lower back, rump, uppertail-coverts, all with metallic blue sheen. White underparts. Pink feet. White patches on wings appear as bar when folded. Caruncles absent. Voice: Male makes call during displays only. IUCN classifies this species as Vulnerable because its very small population and breedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guanay Cormorant
The Guanay cormorant or Guanay shag (''Leucocarbo bougainvilliorum'') is a member of the cormorant family found on the Pacific coast of Peru and northern Chile. (The Argentinian population on the Patagonian Atlantic coast appears to be extirpated.) After breeding it spreads south to southern parts of Chile and north to Ecuador, and has also been recorded as far north as Panama and Colombia – probably a result of mass dispersal due to food shortage in El Niño years. Its major habitats include shallow seawater and rocky shores. The Guanay cormorant is similar in coloration to the rock shag, ''Leucocarbo magellanicus'', but larger, measuring 78 cm from the tip of the bill to the end of the tail. Its bill is grayish with some red at the base. The face is red with a green eye-ring. It has roseate feet. The head, neck and back are black as are the outer parts of the thighs. The throat patch, breast and belly are white. In breeding plumage it has a few white feathers on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Shag
The rock shag (''Leucocarbo magellanicus''), also known as the Magellanic cormorant, is a marine cormorant found around the southernmost coasts of South America. Its breeding range is from around Valdivia, Chile, south to Cape Horn and Tierra del Fuego, and north to Punta Tombo in Argentina. In winter it is seen further north, with individuals reaching as far as Santiago, Chile on the west coast and Uruguay on the east. The birds also breed around the coasts of the Falkland Islands. Taxonomy The rock shag 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 in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus magellanicus''. Gmelin based his description on the "Magellanic shag" that had been described in 1785 by the English ornithologist John Latham in his book ''A General Synopsis of Birds''. Latham had in turn based his description on a specime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-crested Cormorant
The double-crested cormorant (''Nannopterum auritum'') is a member of the cormorant family of water birds. It is found near rivers and lakes, and in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring in length, it is entirely black except for a bare patch of orange-yellow facial skin and some extra plumage that it exhibits in the breeding season, when it grows a double crest in which black feathers are mingled with white. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years. Taxonomy The double-crested cormorant was described by René Primevère Lesson in 1831. It was formerly classified in the genus '' Phalacrocorax'', but a 2014 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotropic Cormorant
The neotropic cormorant or olivaceous cormorant (''Nannopterum brasilianum'') is a medium-sized cormorant found throughout the American tropics and subtropics, from the middle Rio Grande and the Gulf and Californian coasts of the United States south through Mexico and Central America to southern South America, where it is called by the indigenous name of ''biguá''. It also breeds on the Bahamas, Cuba and Trinidad. It can be found both at coasts (including some mangrove areas) and on inland waters. There are at least two subspecies: ''N. b. mexicanum'' from Nicaragua northwards and ''N. b. brasilianum'' further south. In Peru the neotropic cormorant is used by the Uru people for fishing. Taxonomy The neotropic cormorant was documented in 1658 by the Dutch naturalist Willem Piso after travels in Brazil. This formed the basis for the formal description and naming of the species by Johann Friedrich Gmelin in 1789. He placed it with the petrels in the genus ''Procellaria'' and coined ...

Flightless Cormorant
The flightless cormorant (''Nannopterum harrisi''), also known as the Galapagos cormorant, is a cormorant endemic to the Galapagos Islands, and an example of the highly unusual fauna there. It is unique in that it is the only known cormorant that has lost the ability to fly. It was placed in its own genus, ''Nannopterum'', but then was later placed with most of the other cormorants in the genus '' Phalacrocorax''. A 2014 study supported reclassifying it and two other American cormorant species back into ''Nannopterum''. The IOC followed this classification in 2021. Description The flightless cormorant is the largest extant member of its family, in length and weighing , and its wings are about one-third the size that would be required for a bird of its proportions to fly. The keel on the breastbone, where birds attach the large muscles needed for flight, is also significantly reduced. Like all cormorants, this bird has webbed feet and sturdy legs that propel it through th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Shag
The European shag or common shag (''Gulosus aristotelis'') is a species of cormorant. It is the only member of the monotypic genus ''Gulosus''. It breeds around the rocky coasts of western and southern Europe, southwest Asia and north Africa, mainly wintering in its breeding range except for the northernmost birds. In Britain this seabird is usually referred to as simply the shag. The scientific genus name derives from the Latin for glutton. The species name ''aristotelis'' commemorates the Greek philosopher Aristotle. Taxonomy The European shag was formerly classified within the genus ''Phalacrocorax'', but a 2014 study found it to be significantly more diverged than the clade containing ''Phalacrocorax'' and ''Urile'', but basal to the clade containing ''Nannopterum'' and ''Leucocarbo'', and thus classified it in its own genus, ''Gulosus''. The IOC followed this classification in 2021. ''Gulosus'' is thought to have split from the ''Nannopterum''-''Leucocarbo'' clade betwe ...

Great Cormorant
The great cormorant (''Phalacrocorax carbo''), known as the black shag in New Zealand and formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (''phalakros'', "bald") and κόραξ (''korax'', "raven"), and ''carbo'' is Latin for "charcoal". It breeds in much of the Old World, Australia, and the Atlantic Ocean, Atlantic coast of North America. Taxonomy and etymology The long white-breasted cormorant ''P. c. lucidus'' found in sub-Saharan Africa, has a white neck and breast. It is often treated as a full species, ''Phalacrocorax lucidus'' (e.g. , ). In addition to the Australasian and African forms, ''Phalacrocorax carbo novaehollandiae'' and ''P. c. lucidus'' mentioned above, other geographically distinct subspecies are recognised, including ''P. c. sinensis' ...

White-breasted Cormorant
The white-breasted cormorant (''Phalacrocorax lucidus'') is much like the widespread great cormorant and if not a regional variant of the same species, is at least very closely related. It is distinguished from other forms of the great cormorant by its white breast and by the fact that subpopulations are freshwater birds.J.A. Harrison, D.G. Allan, L.G. Underhill, M. Herremans, A.J. Tree, V. Parker, C.J. Brown (eds). The Atlas of Southern African Birds. Published by BirdLife South Africa, P.O. Box 84394, Greenside 2034, Johannesburg, South Africa 1997 ''Phalacrocorax lucidus'' is not to be confused with the smaller and very different endemic South Australian black-faced cormorant, which also is sometimes called the white-breasted cormorant. Taxonomy and description The white-breasted cormorant (''Phalacrocorax lucidus'') is a member of the cormorant family Phalacrocoracidae. Its taxonomic status has been under discussion for some decadesBrooke RK, Cooper J, Shelton PA, Crawford ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
