Anomalies in skin or plumage pigmentation have been recorded across various vertebrate species, albeit infrequently. Factors such as pollution and genetics are indicated as the causes. This study reports for the first time, a case of color aberration (albinism or Brown) in a juvenile Humboldt penguin Spheniscus humboldti individual on the Hualpén Peninsula, Chile, along with an update of the literature comprising 25 reported cases of these anomalies in the Chilean wildlife.
