Rufous-headed Chachalaca
Emits a loud, raucous chachalaca chorus; individual calls are slightly higher than Rufous-vented. Dawn choruses carry across Ecuadorian and Peruvian coastal dry forest.

About These Birds
Sickle-winged Guan
A medium-sized cracid (~700 g) of family Cracidae, with sickle-shaped outer primaries and blue facial skin. Inhabits humid Andean cloud forests and forest edges from Colombia to Bolivia at 900–3,000 m elevation. Arboreal, feeding mainly on small fruits and berries. Least Concern; widely distributed in the Andean cloud forest zone and common in undisturbed montane habitats.
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.
