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. 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 their name. This is the largest species of the forest falcon genus, with a total length of 46 to 58 cm (18 to 23 in), wingspan of 72 to 86 cm (28 to 34 in) and male weights of 467 to 646 g (1.030 to 1.424 lb), averaging...

GBIF citizen-science records
It is estimated from how often the Collared Forest Falcon is recorded against all the birds logged in San José (149 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
