About These Birds
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.
