Habitat

Their breeding habitat is forested areas, mainly deciduous, across most of North America to Central America.

The Downy is a familiar bird in its range, especially in winter, when many move into the suburbs and feed on suet at bird feeders. It is often seen in the mixed flocks of chickadees, nuthatches, creepers, and kinglets that gather in the woods during migration and winter.

Behaviour

Diet

As with other woodpeckers, the male is larger than the female and chisels deep into wood with its longer, stronger bill, whereas the female pries under the bark with her shorter bill. Thus a pair is able to share the food resources without competing with one another.

Breeding

They nest in a tree cavity, excavated by the nesting pair in a dead tree or limb.

Vocalisation

A quiet pik or a descending rattle.
