What are bluebird enemies?

Adults might be taken by snakes, falcons, cats, or other predators. Eggs could be eaten by birds such as jays and crows, snakes, raccoons, or skunks.

Bluebirds have difficulty nesting where other more aggressive birds build nests. Exotics such as the European starling occupy nesting sites that bluebirds prefer. Bluebird habitat is orchard-type habitat, and humans have caused pressure on bluebirds by converting this type of habitat into other uses.
