Mourning dove
The greatest predators of this species are birds of prey, such as falcons and hawks. Other times, during nesting, corvids, grackles, house cats or rat snakes will eat their eggs. Cowbirds rarely pass parasites mourning dove nests. Mourning doves reject slightly under a third of cowbird eggs in such nests, and the cowbirds cannot eat the Mourning Dove's vegetarian diet.
