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.
