Nannopterum
''Nannopterum'' is a genus of cormorant comprising three species. They are found throughout the Americas, hence the common name American cormorants. These species were formerly classified in the genus '' Phalacrocorax''. A molecular phylogenetic study of the cormorants published in 2014 found that these three species formed a clade that was sister to the genus ''Leucocarbo''. To create monophyletic genera, the three species were moved the resurrected genus ''Nannopterum'' that had been introduced in 1899 by English ornithologist Richard Bowdler Sharpe to accommodate the flightless cormorant. The genus ''Nannopterum'' is thought to have split from ''Leucocarbo'' between 6.7 - 8.0 million years ago. The genus name ''Nannopterum'' combines the Ancient Greek ''nannos'' meaning "dwarf" with ''pteron'' meaning "wing". This name was coined for the flightless cormorant, which does indeed have small wings. Genetic studies have found that the neotropic The Neotropical realm is one ...

Nannopterum Brasilianum
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 ...

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] |

Cormorant
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOC adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wings; some cormorant species have been ...

Phalacrocorax Harrisi
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 the wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leucocarbo
''Leucocarbo'' is a genus of birds in the family Phalacrocoracidae with the members commonly known as blue-eyed shags. This is a group of closely related cormorant taxa. Many have a blue, purple or red ring around the eye (not a blue iris); other shared features are white underparts (at least in some individuals) and pink feet. They are found around the colder parts of the Southern Hemisphere, especially near southern South America, Antarctica, and New Zealand. Many are endemic to remote islands. Determining which types are species and which are subspecies of what larger species is problematic; various recent authorities have recognized from 8 to 14 species and have placed them in a variety of genera. The common names are even more confusing, "like myriad footprints criss-crossing in the snow and about as easy to disentangle." Only one common name is given for most species here. Taxonomy The genus ''Leucocarbo'' was introduced in 1856 by the French naturalist Charles Lucien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalacrocorax
''Phalacrocorax'' is a genus of fish-eating birds in the cormorant family Phalacrocoracidae. Members of this genus are also known as the Old World cormorants. Taxonomy The genus ''Phalacrocorax'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the great cormorant (''Phalacrocorax carbo'') as the type species. ''Phalacrocorax'' is the Latin word for a cormorant. Formerly, many other species of cormorant were classified in ''Phalacrocorax'', but most of these have been split out into different genera. A 2014 study found ''Phalacrocrax'' to be the sister genus to ''Urile'', which are thought to have split from each other between 8.9 - 10.3 million years ago. Current taxonomy A molecular phylogenetic study published in 2014 found that the genus ''Phalacrocorax'' contains 12 species. This taxonomy was adopted by the IUCN Red List and BirdLife International, and later by the IOC. Alternative taxonomies Formerly, the genus ''Phalacrocorax'' include ...
