Predators of adults are most likely hawks and owls. Nestlings and eggs are eaten by woodpeckers, small squirrels, and climbing snakes, such as smooth green snakes. White-breasted nuthatches respond to predators near their nest by pecking and flicking their wings while making "hn-hn" noises. They also use a piece of fur or vegetation to wipe around their nest opening when they leave the nest. This covers up their scent and keeps squirrels and other predators from using smell to find their nests.
