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.
Cauca Guan
A medium-large cracid (~1.2 kg) of family Cracidae, with olive-brown plumage and a red throat wattle. Endemic to the upper Cauca Valley of Colombia at 1,200–2,400 m elevation. Inhabits remnant humid Andean forests. Arboreal, feeding on fruits and seeds. Vulnerable due to severe deforestation in one of Colombia's most densely populated valleys and ongoing hunting pressure.
