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-bellied Chachalaca
A larger chachalaca (~834 g) of family Cracidae, with a rufous wash on the underparts. Endemic to the Pacific slope of northwestern Mexico, from Sonora to Jalisco. Inhabits tropical dry forest, thorn scrub, and deciduous woodland. Forages in groups on fruits, seeds, and insects. Least Concern; range restricted to the Mexican Pacific coast but populations remain stable.
