Long-tailed, chickenlike bird restricted to the lowlands of northern Colombia. The chestnut wings may be hidden from view when the bird is perched. It can be separated from the similar Rufous-vented Chachalaca by its white belly and pale (not rusty) tail tips. Distinguished from Colombian Chachalaca by lack of scaling on head and breast. Inhabits lightly wooded areas and mangroves. Easier to see early in the morning and late in the afternoon when it often perches up in the open and gives loud, raucous calls.
