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.
Bearded Guan
A medium-sized cracid (~820 g) of family Cracidae, with a small red-wattled throat pouch. Inhabits montane cloud forests in the Andes of southern Ecuador and northern Peru at 1,500–3,000 m elevation. Feeds arboreally on fruits, seeds, and buds. Near Threatened due to ongoing deforestation and hunting; dependent on intact Andean cloud forest which continues to be cleared.
