Forest Falcon
Forest falcons are members of the genus ''Micrastur'', part of the family Falconidae. They are endemic to the Americas, found from Mexico in the north, south through Central America and large parts of South America, and as far south as northern Argentina. Most are restricted to humid tropical and subtropical forests, but the two most widespread species, the collared and the barred forest falcon, also range into drier and more open habitats. Forest falcons, like most ''Accipiter''-type hawks (but unlike other falcons), are adapted for agility in thick cover rather than outright speed in the open air. They have short wings, long tails, and extraordinarily acute hearing. While generally visually inconspicuous, their songs are commonly heard. Their diet is a mixture of birds, mammals, and reptiles. Hunting is often performed in goshawk fashion: the bird takes up a perch in an inconspicuous position and waits for a prey species to pass, then strikes with a short, rapid pursuit. Fores ...

Collared Forest Falcon
The collared forest falcon (''Micrastur semitorquatus'') is a species of bird of prey in the family Falconidae. It is the largest member of the Micrastur genus and a common inhabitant of tropical rainforests in Latin America. Hiding in the dense forest canopy, they are a secretive bird often only recognized by their distinctive call. With a morphology or body type allowing them to be agile in their forested habitat, their diet comprises a wide variety of prey from smaller frogs (20 g) to adult turkeys (2.7-3.2 kg). Nesting occurs mainly in the cavities of Spanish cedar trees, which are also a key species exploited by the local logging industry. This is a potential conservation concern for the collared forest falcon. Description The collared forest falcon has a dark coloured back with a white neck and breast. The species has three morphological variants ( morphs): pale, tawny and dark. The former two have a light coloured collar at the back of their neck, which explains the ...

Falcons
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 falcon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyborinae
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, just off the coast of the southernmost tip of South America. Taxonomy ...

Buckley's Forest Falcon
Buckley's forest falcon (''Micrastur buckleyi''), also called lesser collared forest-falcon and Traylor's forest-falcon, is a species of bird of prey in subfamily Herpetotherinae of family Falconidae, the falcons and caracaras. It is found in Brazil, Eucador, Peru, and possibly Colombia and Venezuela.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F. Pacheco, M. B. Robbins, F. G.

Slaty-backed Forest Falcon
The slaty-backed forest falcon (''Micrastur mirandollei'') is a species of bird of prey in subfamily Herpetotherinae of family Falconidae, the falcons and caracaras. It is found in Costa Rica, Panama, and every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A.

Cryptic Forest Falcon
The cryptic forest falcon (''Micrastur mintoni'') is a species of bird of prey in the family Falconidae. It is found in the south-eastern Amazon rainforest in Brazil and Bolivia. While uncommon in its Amazonian range, it remains widespread, and is therefore rated as least concern by BirdLife International and IUCN. Unlike the lined forest falcon, with which it has long been confused in a cryptic species complex, adult cryptic forest falcons only have a single white tail-band (in addition to a narrow white tail-tip). Description The cryptic forest falcon is a rarely spotted bird of prey. When spotted, it is often confused for its congeners, the barred forest falcon, the lined forest falcon, and the plumbeous forest falcon. While it differs slightly from its congeners in its physical characteristics, it is best recognized by its distinctive vocalizations. Its height is 30-35 centimeters, and its weight is 170-264 grams for females (171-238 grams for males). Its plumage is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plumbeous Forest Falcon
The plumbeous forest-falcon (''Micrastur plumbeus'') is a bird of prey in the family Falconidae only found in the Chocó region in Colombia and Ecuador. This rare bird has not been often spotted, which makes its study complicated. For a long time, it was considered to be part of the lined forest-falcons but it now known to be a species of its own. It is currently considered a vulnerable species because of the precarity of its habitat that is threatened by deforestation. Description The adult plumbeous forest-falcon has a grey back and a grey head with very bright orange legs and face. Their breast is barred and paler than their back, and their belly is more whitish towards the tail. This raptor has a black tail with a white tip and a white band in the middle, going across the whole width. Their irides are dark brown. The individuals are 30-34 cm (13 in) long and females are bigger than males. As a matter of fact, females weigh 180-213g and males weigh 172-188g. Immature ind ...
