ABSTRACT
Leucism in birds is a genetic disorder characterized by the total absence of melanin in some or all feathers, but unlike albinism, the other body parts, such as eyes, beak, and tarsi remain with the typical color of the species. The House Sparrow Passer domesticus is a bird native from Europe, Asia, and North Africa. It has been introduced in North America, South America, South Africa, Australia, and New Zealand. Currently, it is the bird species with the largest geographical range. Here, we report the record of a leucistic specimen of Passer domesticus from Rodeadouro island, São Francisco river, northeastern Brazil.
