ABerrant plumage in the white-throated piping-guan (pipile grayi pelzeln, 1870, cracidae

Abstract

There is limited information regarding cases of aberrant plumage in Cracidae. Here we present the first record of aberrant plumage in the White-throated Piping-guan (Pipile grayi). The individual with aberrant plumage was predominantly white-colored, but with pale cream underparts. Unfeathered body parts like the fleshy wattle, bill, and tarsus had pink color. Based on these characteristics we conclude that it likely constitutes a case of "Ino-light" mutation.
