Milvago is a genus of bird of prey in the family Falconidae.
Milvago contains two extant species:
| Image | Scientific name | Common Name | Distribution |
|---|---|---|---|
 | Milvago chimachima | Yellow-headed caracara | Costa Rica south through Trinidad and Tobago to northern Argentina (the provinces of Misiones, Chaco, Formosa, Corrientes and Santa Fe) |
 | Milvago chimango | Chimango caracara | Argentina, Uruguay, Chile, Paraguay and south of Brazil. |
They are native to South America and Trinidad and Tobago in the Caribbean, with M. chimachima just reaching to the Isthmus of Panama and into Costa Rica, though recently having expanded its range into the northern part of the country. Prehistorically the genus extended much further north into Cuba and Hispaniola, where it might have become extinct as late as after the arrival of the first humans in the early Holocene [ citation needed ], though there is no evidence for this at present and they more likely disappeared already during the last glacial period.[ citation needed ]
A paleosubspecies of the yellow-headed caracara from Florida is also known.
Falcons are birds of prey in the genus Falco, which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene.
The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae. The family likely originated in South America during the Paleocene and is divided into three subfamilies: Herpetotherinae, which includes the laughing falcon and forest falcons; Polyborinae, which includes the spot-winged falconet and the caracaras; and Falconinae, the falcons and kestrels (Falco) and falconets (Microhierax).
The woodcocks are a group of seven or eight very similar living species of wading birds in the genus Scolopax. The genus name is Latin for a snipe or woodcock, and until around 1800 was used to refer to a variety of waders. The English name is first recorded in about 1050. According to the Harleian Miscellany, a group of woodcocks is called a "fall".
Leiocephalidae, also known as the curlytail lizards or curly-tailed lizards, is a family of iguanian lizards restricted to the West Indies. One of the defining features of these lizards is that their tail often curls over. They were previously regarded as members of the subfamily Leiocephalinae within the family Tropiduridae. There are presently 30 known species, all in the genus Leiocephalus.
Coragyps is a genus of New World vulture that contains the black vulture (Coragyps atratus) and two extinct relatives.
The yellow-headed caracara is new-world bird of prey in the family Falconidae, of the Falconiformes order. It is found as far north as Nicaragua, south to Costa Rica and Panamá, every mainland South American country, and on the Caribbean islands of Aruba, Bonaire, Curaçao, and Trinidad and Tobago.
Tyto is a genus of birds consisting of true barn owls, grass owls and masked owls that collectively make up all the species within the subfamily Tytoninae of the barn owl family, Tytonidae.
Acratocnus is an extinct genus of ground sloths that were found on Cuba, Hispaniola, and Puerto Rico.
Phalcoboenus is a small genus of caracara in the family Falconidae. They are found in barren, open habitats in the Andes, Patagonia and the Falkland Islands. The four species are almost entirely allopatric. The adults are distinctive, with bare yellow, orange or red facial skin and cere, and a black plumage with variable amounts of white. Juveniles are overall brown with pale pinkish-grey facial skin and cere. They are highly opportunistic and typically seen walking on the ground, where they will feed on carrion and virtually any small animal they can catch.
The carunculated caracara is a species of bird of prey in the family Falconidae, the falcons and caracaras. It is found in Colombia and Ecuador.
Megalocnus is a genus of extinct ground sloths that were native to Cuba during the Pleistocene and Holocene epochs. They were among the largest of the Caribbean sloths (Megalocnidae), with individuals estimated to have weighed up to 270 kg to 200 kg, around the size of a black bear when alive. Its relatives include other megalocnid sloths, such as Acratocnus, Mesocnus, Miocnus, Neocnus andParocnus. The former species M. zile from Hispaniola is currently thought to be a junior synonym of Parocnus serus.
Caracara is a genus in the family Falconidae and the subfamily Polyborinae. It contains one extant species, the crested caracara; and one recently extinct species, the Guadalupe caracara. The South American Classification Committee of the American Ornithological Society has voted to again merge the two, retaining C. plancus as crested caracara. The taxonomists of the International Ornithologists' Union have also merged them.
Chelonoidis is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies.
Antigone cubensis, sometimes called the Cuban flightless crane, is a large, extinct species of crane which was endemic to the island of Cuba in the Caribbean. The species was originally placed in the genus Grus, as Grus cubensis, however subsequent study of the genus resulted in moving the species to Antigone in 2020. Subfossil remains were found in Pleistocene deposits in Pinar del Rio. Probably derived from an early invasion of sandhill cranes from North America, it differed from that species by, as well as larger size, having a proportionately broader bill, stockier legs, and with reduced wings and pectoral girdle indicating that it may have been flightless. Currently, the only extant Caribbean crane is the Cuban sandhill crane, Antigone canadensis nesiotes, an endangered subspecies of sandhill crane endemic to the country.
Megalocnidae is an extinct family of sloths, native to the islands of the Greater Antilles from the Early Oligocene to the Mid-Holocene. They are known from Cuba, Hispaniola and Puerto Rico, but are absent from Jamaica. While they were formerly placed in the Megalonychidae alongside two-toed sloths and ground sloths like Megalonyx, recent mitochondrial DNA and collagen sequencing studies place them as the earliest diverging group basal to all other sloths. or as an outgroup to Megatherioidea. They displayed significant diversity in body size and lifestyle, with Megalocnus being terrestrial and probably weighing several hundred kilograms, while Neocnus was likely arboreal and similar in weight to extant tree sloths, at less than 10 kilograms.
Parocnus is an extinct genus of sloth native to Cuba and Hispaniola, belonging to the family Megalocnidae. It was a terrestrial ground sloth, being the second largest Caribbean sloth after Megalocnus.
