Predators of red-winged blackbirds include such species as raccoons, American mink, Long-tailed weasel, Eurasian magpie, Common grackle, the hawks and owls, Red-tailed hawk, short-tailed hawks, and snakes such as the Northern water snake and the Plains garter snake. Ravens and grazers such as Marsh wrens feed on eggs (and even small chicks), if the nest is left unattended, destroying the eggs, occasionally drinking from them, and pecking the nestlings to death.
