Verbreitung und Lebensraum

These birds migrate to southern Arizona and Mexico. As non-breeding residents in the south of their migration range, they are passage migrants over the deserts of the south-western United States, the Mojave, Sonoran, and Chihuahuan Deserts, where they make their stops along the flyway. Their breeding habitat is mountain slopes and foothills with brush and scattered trees (especially ponderosa pine) across western North America. They make a cup nest low in a vertical fork in a shrub.
