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.
White-browed Guan
A large cracid (~1.4 kg) of family Cracidae, with a prominent white supercilium. Endemic to the caatinga scrublands and dry forests of northeastern Brazil. Inhabits dry deciduous forests, gallery forest, and scrubby vegetation. Arboreal frugivore. Vulnerable; one of the few large cracids adapted to Brazil's semi-arid caatinga, threatened by habitat loss and hunting.
