Observaciones de leucismo en cuatro especies de aves acuáticas en Guerrero Negro, Baja California Sur, México

Abstract

We report the occurrence of plumage pigment aberrations in 4 species of waterbirds in Baja California Sur: Egretta rufescens, Larus occidentalis, Podiceps nigricollis, Puffinus opisthomelas. These observations represent the first leucistic records for these species for Mexico. The documentation of such cases can help to understand the impact of chromatic aberrations, and their variation between different groups of birds.
