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 . [1] 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. [2] [3] [4] The genus Nannopterum is thought to have split from Leucocarbo between 6.7 - 8.0 million years ago. [1]
The genus name Nannopterum combines the Ancient Greek nannos meaning "dwarf" with pteron meaning "wing". [5] This name was coined for the flightless cormorant, which does indeed have small wings. Genetic studies have found that the neotropic and double-crested cormorants form a clade with the flightless cormorant, and they are thus placed together in the genus Nannopterum despite both species having normal-sized wings and full flight capabilities.

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 International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant and the common shag 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.
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.
The rosefinches are a genus, Carpodacus, of passerine birds in the finch family Fringillidae. Most are called "rosefinches" and as the word implies, have various shades of red in their plumage. The common rosefinch is frequently called the "rosefinch". The genus name is from the Ancient Greek terms karpos, "fruit", and dakno, "to bite".
The European shag or common shag 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.
The flightless cormorant, 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.
The neotropic cormorant or olivaceous cormorant 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 in the Bahamas, Cuba, and Trinidad. It can be found both on coasts and in 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.
Colaptes is a genus of birds in the woodpecker family Picidae. The 14 species are found across the Americas.
The rock shag, 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.
The New Zealand king shag, also known as the rough-faced shag, king shag or kawau tūī, 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.
Leucocarbo is a genus of birds in the family Phalacrocoracidae. Several species within the genus are collectively 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 ; other shared features are white underparts and pink feet.
The moorland chat, also known as the alpine chat or hill chat, is a species of songbird in the Old World flycatcher family. It is endemic to north-east Africa where it is common in its habitat. It lives at high altitudes on moors and grassland, usually above 3,400 m (11,100 ft), but can live as low as 2,100 m (6,900 ft). It has a short tail and long legs. It is bold and will approach people.
The crimson-headed partridge is a species of bird in the pheasant, partridge, and francolin family Phasianidae. Described by the British ornithologist Richard Bowdler Sharpe in 1879, it is the only species in the genus Haematortyx. It is endemic to Borneo, where it inhabits lower montane forest in the northern and central parts of the island. It is mainly found at elevations of 1,000–1,700 m (3,300–5,600 ft), but can be seen as low as 185 m (607 ft) and as high as 3,050 m (10,010 ft). Adult males have a striking appearance, with a dark blackish body and crimson red heads, necks, breasts, and undertail coverts. Females have a similar pattern, but with duller brownish-black colouration, orangish-red heads and breasts, and a brownish-black bill instead of a yellowish one. Juveniles are duller and have the crimson restricted to the top of the head.
The red-billed starling is a species of starling in the family Sturnidae. It is found in south and southeastern China.
The yellow-bellied flyrobin is a species of passerine bird in the Australasian robin family Petroicidae. It is the only species in the genus Cryptomicroeca. The yellow-bellied flyrobin is endemic to New Caledonia, where it occurs on the island of Grande Terre. It occupies a range of habitats, including dry lowlands, woodland, Pinus and Pandanus forest, and humid forest from sea level up to 1,525 m (5,000 ft).
The Hispaniolan euphonia is a bird species in the finch family, Fringillidae that is endemic to the island of Hispaniola in the Caribbean.
The boulder chat is a species of bird in the thrush family Turdidae native to dry woodland and savanna in Southern Africa. It is the only species in the monotypic genus Pinarornis.
Euodice is a genus of small seed-eating birds in the family Estrildidae. These species are from the dry zones of Africa and India and are commonly referred to as silverbills. They were formerly included in the genus Lonchura.
The order Suliformes is an order recognised by the International Ornithologist's Union. Regarding the recent evidence that the traditional Pelecaniformes is polyphyletic, it has been suggested that the group be divided to reflect the true evolutionary relationships; a 2017 study indicated that they are most closely related to Otidiformes (bustards) and Ciconiiformes (storks).
Pitohui is a genus of birds endemic to New Guinea. The birds formerly lumped together as pitohuis were found by a 2008 study that examined their evolutionary history on the basis of the genetic sequences to have included birds that were quite unrelated to each other. They have since been separated into other genera.
Urile is a genus of birds in the family Phalacrocoracidae, commonly known as North Pacific cormorants. It contains 3 extant and 1 recently extinct species, all of which are or were found in the North Pacific Ocean.
