Micrastur Mintoni - Cryptic Forest Falcon; Parauapebas, Pará, Brazil
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 ...

Accipiter Castanilius
The chestnut-flanked sparrowhawk (''Aerospiza castanilius'') is a small west African species of sparrowhawk in the family Accipitridae. This species was formerly placed in the genus ''Accipiter''. Taxonomy It is closely related to the African goshawk ''Aerospiza tachiro'', albeit smaller than this species. It is normally regarded as monotypic, although some authorities recognise the smaller birds in the Congo Basin as the subspecies ''Aerospiza castanilius beniensis''. Description Chestnut-flanked sparrowhawk has blackish grey upperparts with a very distinctive pattern on the underparts; the breast and belly are heavily barred grey and brown, with chestnut colored flanks. The throat is white and the head is rather broad compared to similar species. The cere is yellow as is the thin eyering which surrounds the red eye. Females and juveniles are browner. They sit tall and have a wingspan of . Distribution and habitat The chestnut-flanked sparrowhawk occurs in west central Afric ...

Buckley's Forest Falcon

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 southeastern 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 grey (of ...

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 indiv ...
