The Choco toucan is long and weighs . The sexes are alike though the female's bill is shorter than the male's. Their bill's maxilla is mostly yellow with some green on the culmen and a black triangle at its base. Their mandible is black, sometimes with a yellow tip. Their crown and nape are black with a maroon tinge; their upperparts and tail are black except for white uppertail coverts. Bare yellow-green to olive green skin surrounds their eye. Their throat and breast are yellow with a narrow red band below the breast. Their belly is black and their undertail coverts red. The plumage is almost identical to that of the "chestnut-mandibled" subspecies of channel-billed toucan (R. v. swainsonii), with which there is a range overlap, but their voices separate them.Short, L.L. and C.
