Crax alector (Black Curassow)

Wikipedia Abstract

The black curassow (Crax alector), also known as the smooth-billed curassow and the crested curassow, is a species of bird in the Cracidae family, the chachalacas, guans, and curassows. It is found in humid forests in northern South America in Colombia, Venezuela, the Guianas and far northern Brazil. 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, and have a yellow (eastern part of its range) or orange-red (western part of its range) cere.
