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.
Band-tailed Guan
A medium-sized cracid (~800 g) of family Cracidae, with a distinctive pale-tipped tail band. Inhabits montane humid forests in the Sierra Nevada de Santa Marta and Andes of Colombia and Venezuela. Arboreal, feeding on fruits, seeds, and buds in the canopy. Least Concern; restricted to Andean cloud forest but common within its range and tolerates some forest disturbance.
