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.
Blue-throated Piping-guan
A large cracid (~1.2 kg) of family Cracidae, with white wing markings and a bright blue throat wattle. Inhabits humid lowland and foothill forests across northern South America, from Colombia and Venezuela south through Amazonia to Bolivia. Arboreal, feeding on fruits and seeds. Least Concern; widespread in Amazonian forests with relatively stable populations in undisturbed areas.
