The rufous-bellied chachalaca is 62 to 67 cm (2.0 to 2.2 ft) long and weighs about 834 g (1.8 lb). Most of its plumage is gray brown to olive brown, but its chestnut belly and tail tips make it the most richly colored member of its genus. It has bare pink and blue skin around the eye.
The rufous-bellied chachalaca is found in western Mexico from southern Sonora south to northwestern Jalisco. It inhabits tropical deciduous, semi-deciduous, and thorn forest and, along the coast, mangroves. In elevation it usually ranges from sea level to 1,300 m (4,300 ft) but has been found as high as 2,000 m (6,600 ft).
The rufous-bellied chachalaca forages in groups of up to 10, gleaning fruit from trees.
Little is known about the rufous-bellied chachalaca's breeding phenology. Its breeding season appears to center around June. The clutch size is usually three eggs.
