About These Birds
Nocturnal Curassow
A medium-large cracid (~1.4 kg) of family Cracidae, the only curassow known for crepuscular and nocturnal activity. Has reddish-brown barred plumage and a small crest. Inhabits humid lowland rainforest in the western Amazon basin in Colombia, Ecuador, Peru, and Brazil. Feeds on fruits and invertebrates. Least Concern; secretive behavior and dense forest habitat provide natural protection.
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.
