The black curassow (Crax alector), also known as the smooth-billed curassow and the crested curassow, is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in humid forests in northern South America in Colombia, Venezuela, the Guianas including Suriname, and far northern Brazil, and is introduced to Bahamas, Cuba, Jamaica, Haiti, Dominican Republic, Puerto Rico and Lesser Antilles. It is the only Crax curassow where the male and female cannot be separated by plumage, as both are essentially black with a white crissum (the area around the cloaca), and have a yellow (eastern part of its range) or orange-red (western part of its range) cere.
The black curassow is a large bird reaching about 900 millimetres (35 in) in length. The male has black upper parts glossed with a purplish sheen and an inconspicuous black crest. The skin at the base of the grey beak is yellow... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Curassow is recorded against all the birds logged in Sierra de la Macarena National Park (9 verified sightings from 2019 to 2026), 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.
