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.
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates. In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species also scavenge and eat carrion.
The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae. The family 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).
Moa are an extinct group of flightless birds formerly endemic to New Zealand. During the Late Pleistocene-Holocene, there were nine species. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 metres (12 ft) in height with neck outstretched, and weighed about 230 kilograms (510 lb) while the smallest, the bush moa, was around the size of a turkey. Estimates of the moa population when Polynesians settled New Zealand circa 1300 vary between 58,000 and approximately 2.5 million.
The yellow-headed caracara is a bird of prey in the family Falconidae, the falcons and caracaras. It is found in Nicaragua, Costa Rica, Panama, every mainland South American country except Chile, and on Aruba, Bonaire, Curaçao, and Trinidad and Tobago.
Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to Late Pleistocene. They include some of the largest known flying birds.
The Ibiza rail is a recently discovered fossil species of rail, described from a late Pleistocene to Holocene cave deposit at Es Pouàs, on the island of Ibiza. Ibiza is in the Pityuses group of the Spanish Balearic Islands in the Mediterranean Sea. The Ibiza rail was a relative of the extant water rail and may be derived from it, but was a bit smaller and stouter, had shorter and more robust hind limbs and shorter wings, with probably reduced its flight capability. Consequently, it might have also occurred on neighbouring Formentera, where no possible locations have been surveyed.
The striated caracara or Forster's caracara is a Near Threatened bird of prey of the family Falconidae, the falcons and caracaras. It is found in Argentina, Chile, and the Falkland Islands. In the Falklands it is known as the Johnny rook, probably named after the Johnny penguin.
The crested caracara is a bird of prey in the family Falconidae. It is found throughout Central and South America but has been found in northern Minnesota to Tierra del Fuego. It was formerly placed in the genus Polyborus.
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 black caracara is a species of bird of prey in the family Falconidae found in Amazonian and French Guiana lowlands, commonly along rivers. They are locally referred to as Ger' futu busikaka in the Republic of Suriname or juápipi {nẽjõmbʌ} by the Emberá of Panama and Colombia. Both these names refer to multiple bird species within Falconidae. German-Brazilian ornithologist Helmut Sick also referred to this species as gavião-de-anta, literally translating to "tapir-hawk".
The chimango caracara is a species of bird of prey in the family Falconidae, the falcons and caracaras. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay, and as a vagrant on the Falkland Islands.
Milvago is a genus of bird of prey in the family Falconidae.
The mountain caracara, is a species of bird of prey in the family Falconidae. It is found in puna and páramo in the Andes, ranging from northern Ecuador, through Peru and Bolivia, to northern Argentina and Chile. It is generally uncommon to fairly common. It resembles the closely related Carunculated Caracara and White-throated Caracara, but unlike those species, its chest is uniform black. Juveniles are far less distinctive than the red-faced pied adults, being overall brown with dull pinkish-grey facial skin.
Caracara is a genus in the family Falconidae and the subfamily Polyborinae. It contains one extant species, the crested caracara; and one 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.
Oryzomys antillarum, also known as the Jamaican rice rat, is an extinct rodent of Jamaica. A member of the genus Oryzomys within the family Cricetidae, it is similar to O. couesi of mainland Central America, from where it may have dispersed to its island during the last glacial period. O. antillarum is common in subfossil cave faunas and is also known from three specimens collected live in the 19th century. Some historical records of Jamaican rats may pertain to it. The species probably became extinct late in the 19th century, perhaps due to the introduction of the small Indian mongoose, competition with introduced rodents such as the brown rat, and habitat destruction.
A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. The region—specifically, all islands in the Caribbean Sea and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeographically belong to the same Caribbean bioregion—has been home to several families found nowhere else, but much of this diversity is now extinct.
The Cuban kestrel was a species of small falcon in the family Falconidae that was formerly endemic to the island of Cuba. It was described from fossil remains from late Quaternary deposits from several sites throughout the island.
