About These Birds
Razor-billed Curassow
A large cracid (~2.9 kg) of family Cracidae, named for its laterally compressed, razor-like red bill. Inhabits lowland Amazonian rainforest in central and eastern Brazil, Bolivia, and Peru. Forages on the forest floor and in the canopy for hard seeds and fruits. Near Threatened due to intensive hunting for food and sport throughout the Amazon basin.

Inhabits Andean cloud forests and forest edges from Venezuela south to Bolivia at elevations of 1,200–3,500 m. Feeds on fruits, seeds, and invertebrates. Least Concern; widespread in montane Andes and one of the more commonly encountered Penelope guans.
