Caracaras
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. Unlike the ''Falco'' falcons in the same family, the birds in the five relevant genera are not fast-flying aerial hunters, but are comparatively slow and are often scavengers (a notable exception being the red-throated caracara). Species Distribution The caracaras are found throughout much of the Americas. The range of the crested caracara extends as far north as the states of Arizona, Texas, and Florida in the United States. In the Southern Hemisphere, the striated caracara inhabits the Falkland Islands and Tierra del Fuego Tierra del Fuego (, ; Spanish for "Land of the Fire", rarely also ...

Mountain Caracara
The mountain caracara (''Phalcoboenus megalopterus''), (Spanish: corequenque) is a species of bird of prey in the family Falconidae. It is found in Puna grassland, 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. Juvenile (organism), Juveniles are far less distinctive than the red-faced piebald, pied adults, being overall brown with dull pinkish-grey facial skin. Description A medium-sized caracara with a faintly blue beak tip turning to bright orange, strongly contrasted by the jet-black feathers of its head, back and chest. Its rump, belly and upper tail and undertail coverts are pure white, changing sharply from black to white between the belly and chest. Its black wings have small white shoulder patches and it has white spots on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Crested Caracara (Caracara Plancus) In Flight
The crested caracara (''Caracara plancus'') is a bird of prey in the family Falconidae. It is found from the southern United States through Central and South America to Tierra del Fuego. It was formerly placed in the genus ''Polyborus''. Description The crested caracara has a total length of and a wingspan of . Its weight is , averaging in seven birds from Tierra del Fuego.''CRC Handbook of Avian Body Masses, 2nd Edition'' by John B. Dunning Jr. (Editor). CRC Press (2008), . Individuals from the colder southern part of its range average larger than those from tropical regions (as predicted by Bergmann's rule) and are the largest type of caracara. In fact, they are the second-largest species of falcon in the world by mean body mass, second only to the gyrfalcon. The cap, belly, thighs, most of the wings, and tail tip are dark brownish, the auriculars (feathers surrounding the ear), throat, and nape are whitish-buff, and the chest, neck, mantle, back, upper tail coverts, crissum ( ...

Black Caracara
The black caracara (''Daptrius ater'') 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 '' 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". Since migration has not been observed, they are considered sedentary; remaining in the tropics year round. Its genus ''Daptrius'' is often considered monotypic today, though some also include its close relative, the red-throated caracara otherwise separated in ''Ibycter''. ''Daptrius ater'' are considered to be a widespread raptor, often spotted in groups of 2-5 individuals in tall trees. Nests built from sticks containing 2-3 spotted, brown eggs have been observed high up in trees, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caracara (genus)
''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. Appearance The crested caracara is distinguished by its long legs and medium size. The birds can reach a length of from head to tail. There are usually four points of identification of the caracara: strikingly white markings on the neck, the tip of both wings, and the tail. Along with their medium length, the caracara also has a wingspan of . When flying, the caracara is often noted to have a pattern on their underside that looks like a cross. Behavior The behaviors of caracaras are considered quite strange in relation to those of other falcons. The b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falconidae
The falcons and caracaras are around 60 species of diurnal birds of prey that make up the family Falconidae (representing all extant species in the order Falconiformes). The family is divided into three subfamilies, Herpetotherinae, which includes the laughing falcon and forest falcons, Polyborinae, which includes the caracaras, '' Spiziapteryx'' and Falconinae, the falcons and kestrels (''Falco'') and falconets (''Microhierax''). Description Falcons and caracaras are small to medium-sized birds of prey, ranging in size from the black-thighed falconet, which can weigh as little as , to the gyrfalcon, which can weigh as much as . They have strongly hooked bills, sharply curved talons and excellent eyesight. The plumage is usually composed of browns, whites, chestnut, black and grey, often with barring of patterning. There is little difference in the plumage of males and females, although a few species have some sexual dimorphism in boldness of plumage. Distribution and habit ...

Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). 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 (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

Pieter Boddaert
Pieter Boddaert (1730 – 6 May 1795) was a Dutch physician and natural history, naturalist. Early life, family and education Boddaert was the son of a Middelburg jurist and poet by the same name (1694–1760). The younger Pieter obtained his M.D. at the University of Utrecht in 1764. Career He became a lecturer on natural history at his alma mater, University of Utrecht. Fourteen letters survive of his correspondence with Carl Linnaeus between 1768 and 1775. He was a friend of Albert Schlosser, whose Cabinet of curiosities, cabinet of "curiosities" of natural history he described. In 1783 he published 50 copies of an identification key of Edmé-Louis Daubenton's ''Planches enluminées'', the colored plates of illustrations for the comte de Buffon's monumental ''Histoire Naturelle'' (published 1749–1789), assigning binomial scientific names to the plates. As many of these were the first Linnaean taxonomy, Linnaean scientific names to be proposed, they remain in use. In 2017 the ...

Falcon
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. Adult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a broad wing. This makes flying easier while learning the exceptional skills required to be effective hunters as adults. The falcons are the largest genus in the Falconinae subfamily of Falconidae, which itself also includes another subfamily comprising caracaras and a few other species. All these birds kill with their beaks, using a tomial "tooth" on the side of their beaks—unlike the hawks, eagles, and other birds of prey in the Accipitridae, which use their feet. The largest fal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...
