About These Birds
Crestless Curassow
A large cracid (~2.3 kg) of family Cracidae, with black plumage, white-tipped tail, and a red bill without a prominent crest. Inhabits lowland humid forests in the Orinoco and northern Amazon basins of Venezuela, Colombia, and Brazil. Forages on the forest floor and in the canopy for fruits and seeds. Least Concern with stable populations in remote forests.

A medium-sized cracid (~630 g) of family Cracidae, with a striking rufous head. Inhabits humid and deciduous forests, forest edges, and scrub in western Ecuador and northwestern Peru. Feeds on fruits and leaves in the forest understory and canopy. Vulnerable due to extensive deforestation in the Tumbesian region, one of the world's most threatened biodiversity hotspots.
