Resumo

Cases of birds with aberrant coloring are not an uncommon sight in the wild, but they need to be documented in specialized literature. These abnormalities may be associated with distinct factors, which can be environmental, genetic, food, diseases, exposure to parasites and age, causing increase and/or reduction of melanin, such as carotenism, in the affected species. We are presenting a report of Rufous-browed Peppershrike (Cyclarhis gujanensis) with aberrant coloring in southern Brazil. The specimen had some feathers in the head’s region depigmented to a whitish hue, mixed with feathers presenting regular coloring. Other bare parts and the remaining plumage present normal color. The report is about progressive graying, in what we believe is the first record of aberrant coloring for C. gujanensis through its known distribution.
