About These Birds
Andean Guan
A medium-sized cracid (~650 g) of family Cracidae, with dull brown-olive plumage and a bare red throat wattle. Inhabits Andean cloud forests and forest edges from Venezuela south to Bolivia at elevations of 1,200–3,500 m. Feeds on fruits, seeds, and invertebrates. Least Concern; widespread in montane Andes and one of the more commonly encountered Penelope guans.
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.
