Title: Overlap in the diets of diurnal raptors breeding at the Michilia biosphere reserve, Durango, Mexico
Abstract: We studied the diets of the Turkey Vulture (Cathartes aura), Black Hawk (Buteogallus anthracinus), Zone-tailed Hawk (Buteo albonotatus), Red-tailed Hawk (B. jamaicensis), Cooper's Hawk (Accipiter cooperii) and American Kestrel (Falco sparverius) by examining pellets collected during 1981 and 1982 breeding seasons in the reserve of La Michilla, Durango, Mexico. Diet overlap was small. The Turkey Vulture and the Black Hawk had little overlap by feeding on restricted types of food (carrion and fish). Hawks (Buteo and Accipiter) ate prey of similar types and sizes but hunted in different habitats and captured different species. The American Kestrel ate the same prey as the Red-tailed Hawk but selected younger and smaller individuals.
