The American green kingfishers are the kingfisher genus Chloroceryle, which are native to tropical Central and South America, with one species extending north to south Texas.
The genus Chloroceryle was introduced in 1848 by the German naturalist Johann Jakob Kaup. [3] Kaup did not specify a type species but Richard Bowdler Sharpe designated the American pygmy kingfisher in 1871. [4] [5] The genus name combines the Ancient Greek khlōros meaning "green" with the genus Ceryle that was introduced by Friedrich Boie in 1828. [6]
The genus contains four species: [7]

The American green kingfishers breed by streams in forests or mangroves, nesting in a long horizontal tunnel made in a river bank.
They have the typical kingfisher shape, with a short tail and long bill. All are plumaged oily green above, and the underpart colour shows an interesting pattern insofar as the smallest and second largest, American pygmy kingfisher and green-and-rufous kingfisher, have rufous underparts, whereas the largest and second smallest, Amazon kingfisher and green kingfisher, have white underparts with only the males also having a rufous breast band.
These birds take crustaceans and fish caught by the usual kingfisher technique of a dive from a perch or brief hover, although the American pygmy kingfisher will hawk at insects in flight.
These water kingfishers are descended from a common ancestor which seems to have been closely related to a progenitor of the pied kingfisher (which at that stage had not yet lost the metallic plumage tone), and are similar in plumage and habits (Moyle, 2006). All four have overlapping ranges, and may fish the same waters; however the weight ratio of aenea: americana: inda: amazona is almost exactly 1:2:4:8, which prevents direct competition for food. The ringed kingfisher, Megaceryle torquata, a more distant relative, also occurs on the same rivers, but is twice as heavy as the Amazon kingfisher.
Genetically, the largest species, C. amazona, is the most distantly related, while the medium-sized (but differently colored) C. americana and C. inda are sister species. The differing coloration therefore does not indicate their evolutionary history, but rather seems to have evolved independently, to underscore the visual distinctness between taxa, thus helping to keep their gene pools separate (see also Competitive exclusion principle).
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly coloured birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species living in the tropical regions of Africa, Asia, and Oceania, but also can be found in Europe and the Americas. They can be found in deep forests near calm ponds and small rivers. The family contains 118 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests.
The belted kingfisher is a large, conspicuous water kingfisher, native to North America. All kingfishers are placed in one family, Alcedinidae, and recent research suggests that this should be divided into three subfamilies.
The river kingfishers or pygmy kingfishers, subfamily Alcedininae, are one of the three subfamilies of kingfishers. The river kingfishers are widespread through Africa and east and south Asia as far as Australia, with one species, the common kingfisher also appearing in Europe and northern Asia. This group includes many kingfishers that actually dive for fish. The origin of the subfamily is thought to have been in Asia.
The water kingfishers or Cerylinae are one of the three subfamilies of kingfishers, and are also known as the cerylid kingfishers. All six American species are in this subfamily.
The pied kingfisher is a species of water kingfisher widely distributed across Africa and Asia. Originally described by Carl Linnaeus in 1758, it has five recognised subspecies. Its black and white plumage and crest, as well as its habit of hovering over clear lakes and rivers before diving for fish, make it distinctive. Males have a double band across the breast, while females have a single broken breast band. They are usually found in pairs or small family groups. When perched, they often bob their head and flick up their tail.
The malachite kingfisher is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements.
The green kingfisher is a species of "water kingfisher" in the subfamily Cerylinae of the family Alcedinidae. It is found from southern Texas in the United States south through Central America, in every mainland South American country except Chile and Trinidad and Tobago.
Megaceryle is a genus of very large kingfishers. They have a wide distribution in the Americas, Africa, and Southeast Asia.
The Amazon kingfisher is a species of "water kingfisher" in subfamily Cerylinae of family Alcedinidae. It is found in the lowlands of the American tropics from southern Mexico south through Central America to northern Argentina.
The American pygmy kingfisher is a species of "water kingfisher" in subfamily Cerylinae of family Alcedinidae. It is found in the American tropics from southern Mexico south through Central America into every mainland South American country except Chile and Uruguay. It also occurs on Trinidad.
The African pygmy kingfisher is a small insectivorous kingfisher found in the Afrotropics, mostly in woodland habitats.
The crested kingfisher is a very large kingfisher that is native to parts of southern Asia, stretching eastwards from the Indian Subcontinent towards Japan. It forms a species complex with the other three Megaceryle species.
Todiramphus is a genus of kingfishers in the subfamily Halcyoninae that are endemic to the Philippines, New Guinea, Australia, New Zealand and many islands in the South Pacific.
The banded kingfisher is a tree kingfisher found in lowland tropical forests of southeast Asia. It is the only member of the genus Lacedo. Male and female adults are very different in plumage. The male has a bright blue crown with black and blue banding on the back. The female has rufous and black banding on the head and upperparts.
The green-and-rufous kingfisher is a species of "water kingfisher" in subfamily Cerylinae of family Alcedinidae. It is found in the American tropics from Nicaragua to Panama and in every mainland South American country except Argentina, Chile, and Uruguay.
Alcedo is a genus of birds in the kingfisher subfamily Alcedininae. The genus was introduced by Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae. The type species is the common kingfisher. Alcedo is the Latin for "kingfisher".
The Malagasy kingfisher or Madagascar kingfisher is a species of bird in the family Alcedinidae that is found in Madagascar, Mayotte and the Comoros. Its natural habitat is subtropical or tropical mangrove forests.
The black-backed dwarf kingfisher, also known as the three-toed kingfisher, is a pocket-sized bird in the family Alcedinidae. It was formerly considered as conspecific with the rufous-backed dwarf kingfisher and together the species complex was known by the English name "oriental dwarf kingfisher".
The brown-headed paradise kingfisher, also known as the russet paradise kingfisher, is a species of bird in the family Alcedinidae. It is endemic to the lowland forest in the Bird's Tail Peninsula. Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. Like all paradise kingfishers this bird has colourful plumage with a red bill and distinctive long tail streamers. No subspecies are distinguished.
Ispidina is a genus of small insectivorous African river kingfishers.
