About These Birds
Rufous-headed Chachalaca
A medium-sized cracid (~630 g) of family Cracidae, with a striking rufous head. Inhabits humid and deciduous forests, forest edges, and scrub in western Ecuador and northwestern Peru. Feeds on fruits and leaves in the forest understory and canopy. Vulnerable due to extensive deforestation in the Tumbesian region, one of the world's most threatened biodiversity hotspots.
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.
