The tendency of Turkey Vultures (Cathartes aura) to perch at some particular site other than the overnight roost, both in morning and evening, appears to be predictable and universal within the species. As with many components of Turkey Vulture behavior, very similar behavior is shown by the California Condor (Gymnogyps californianus; Koford 1953) and the Andean Condor (Vultur gryphus; McGahan 1972). At a large roost in southeastern Oregon, I observed the arrival and departure times of Turkey Vultures, and their movements to and from different perching sites.
