Color Aberrations in Two Species of New World Vultures (Cathartidae)

Abstract: ∙ We present information on two cases of color aberrations in two species of vultures: one individual of Turkey Vulture (Cathartes aura) in Mexico and one of Black Vulture (Coragyps atratus) in Costa Rica. Both cases were determined to be ino, wherein birds have very pale brown eumelanin. We discuss these two cases and compare them with other cases of abnormally colored vultures from several island and mainland areas in America. Resumen ∙ Aberración de color en dos especies de buitres del Nuevo mundo Presentam… Show more

The white motmot was apparently in good physical condition, and had overcome its nestling and fledgling stages without apparent problems.…”

“…, Rodríguez-Cassanova 2019,Mora & Rodríguez-Ruiz 2019, Barragán-Farías et al 2019, Gómez-Garduño et al 2020. De ellos, 27 reportes en 22 especies corresponden al encanecimiento progresivo, lo que representa el 50% de las anormalidades pigmentarias conocidas en México, pero solo uno en el pinzón común (Haemorhous mexicanus) corresponde a un caso de xantocroísmo(Barragán-Farías et al 2019).…”
