Abstract

Plumage coloration plays an important role in camouflage, communication, and physiological processes in birds. Although various pigmentary aberrations of bird plumage have been documented in Venezuela, here we present the first documented case of a Black-bellied Whistling Duck with progressive graying or partial leucism. It is one of the few ducks with documented plumage aberrations in Venezuela and the Americas.
