Abstract

Plumage aberrations in birds are not unusual and have been sporadically mentioned in literature, in which different patterns and variations are described. Leucism is an inherited disorder, characterized on birds by the lack of pigments in part or all of the plumage, and normal coloration of soft parts such as the bill, eyes, and legs. We present here the fi rst record of total leucism in Magnifi cent Frigatebird Fregata magnifi cens, and the fi rst for the species in Venezuela. Long-term studies are needed in the Neotropical region to evaluate survival and breeding success in leucistic birds.
