Abstract

We report 5 cases of progressive graying on the Great-tailed Grackle (Quiscalus mexicanus) and 1 case of white feathers, most likely due to injury, from northeastern Mexico and southern Texas, USA. The cases we report showed different degrees of intensity. The causes of graying in bird feathers are not clear; we discuss possible causes and external factors associated with it and highlight the importance of documenting cases of pigmentary abnormalities.

Reportamos 5 casos de encanecimiento progresivo en el zanate mayor (Quiscalus mexicanus) y un caso de plumas blancas, posiblemente por lesión, en el noreste de México y el sur de Texas, EE. UU. Los casos que reportamos muestran diferentes grados de intensidad. Las causas del encanecimiento de las plumas de las aves no están claras; discutimos las posibles causas y factores externos asociados con ella, y enfatizamos la importancia de documentar casos de anomalías pigmentarias.

Palabras clave: aberraciones cromáticas, albinismo, canoso progresivo, leucismo.
