- Abstract
Chromatic aberrations resulting in abnormally white plumage in birds are generally due to genetic mutations, although some are of non-hereditary origin. Other anomalies may result in only a few white feathers or other alterations in the quantity, quality, and deposition of eumelanin and phaeomelanin. In the Clay-colored Thrush, Turdus grayi, there has been one reported case of total Leucism in Honduras, two cases of partial Leucism in Mexico, another in Costa Rica, and one more in Colombia. This bird is found from Mexico to Colombia where it inhabits altered environments such as forest edges, gardens, and open areas in general, being very common in Costa Rica. The Clay-colored Thrush has a uniform cinnamon-colored plumage, with a light brown head and back. In this work, we report a previously unreported aberration for this bird based on a dirty-white individual observed in the Lower Montane Rain Forest of central Costa Rica.
