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.
White-winged Guan
A large cracid (~1.7 kg) of family Cracidae, with distinctive white primary feathers visible in flight. Endemic to dry forests of the Tumbes region in northwestern Peru. Inhabits deciduous and semi-humid forests in ravines and hillsides. Arboreal frugivore. Endangered; rediscovered in 1977 after being presumed extinct, with ongoing conservation through captive breeding and habitat protection.
