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.
Red-faced Guan
A large cracid (~1.2 kg) of family Cracidae, with distinctive red bare facial skin. Inhabits montane humid forests of the eastern Andes in Bolivia and northwestern Argentina at 900–2,500 m elevation. Arboreal, foraging for fruits, seeds, and buds in the forest canopy. Least Concern; relatively restricted range in the Yungas forest zone but not considered under immediate threat.
