Habitat

Their breeding habitat is open wooded areas in western North America. These birds migrate to South America at the end of summer. The female lays two or three eggs in an open cup nest on a horizontal tree branch or within a tree cavity; California black oak forests are examples of suitable nesting habitat for this species of bird. Both parents feed the young.
