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).
Wrens are a family of brown passerine birds in the predominantly New World family Troglodytidae. The family includes 88 species divided into 19 genera. Only the Eurasian wren occurs in the Old World, where, in Anglophone regions, it is commonly known simply as the "wren", as it is the originator of the name. The name wren has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens (Maluridae).
The peregrine falcon, also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest member of the animal kingdom. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.
Caracaras are birds of prey in the family Falconidae. They are traditionally placed in subfamily Polyborinae with the forest falcons, but are sometimes considered to constitute their own subfamily, Caracarinae, or classified as members of the true falcon subfamily, Falconinae. Caracaras are principally birds of South and Central America, just reaching the southern United States.
Alcide Charles Victor Marie Dessalines d'Orbigny was a French naturalist who made major contributions in many areas, including zoology, palaeontology, geology, archaeology and anthropology.
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, also known as the Mexican eagle, 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.
The long-winged harrier is a common bird of prey species endemic to South America. They are members of the family Accipitridae, under the genus Circus which encompasses other harrier species. Its range encompasses most of South America, in grassland and wetland all across the continent. The long-winged harrier is a carnivorous bird, and will feed on many different animals found in its habitat. Like owls and other harrier species, the long-winged harrier has a distinctive facial disc, which is used to triangulate the bird's hearing while it is hunting.
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.
The white-throated caracara or Darwin's caracara is a species of bird of prey in the family Falconidae, the falcons and caracaras. It is found in Argentina and Chile.
The wildlife of Chile is very diverse because of the country's slender and elongated shape, which spans a wide range of latitude, and altitude, ranging from the windswept coastline of the Pacific coast on the west to northern Andes to the sub-Antarctic, high Andes mountains in the east. There are many distinct ecosystems.
The wildlife of the Falkland Islands is quite similar to that of Patagonia. The Falkland Islands have no native reptiles or amphibians, and the only native land mammal, the warrah, is now extinct. However, a large number of bird species have been seen around the islands, and many of them breed on the smaller islands of the archipelago. Insects play a large role in the ecosystem of the islands, and over 200 species have been recorded. The waters around the Falkland Islands sustain many animals, including a large number of marine mammals. Three pinniped species breed on the islands.
The Patagonian grasslands (NT0804) is an ecoregion in the south of Argentina. The grasslands are home to diverse fauna, including several rare or endemic species of birds. There are few protected areas. The grasslands are threatened by overgrazing by sheep, which supply high-quality merino wool. Efforts are being made to develop sustainable grazing practices to avoid desertification.
