During the summer, the yellow-headed blackbird migrates north to the west-central portions of Canada and the United States. Its range extends as far west as central-interior British Columbia, moving directly south through the central-interior west coast to northeastern Baja California. The eastern edge of the Yellow-headed Blackbird's range extends from western Ontario to northern Missouri.

During the winter, it can be found from California to Texas as well as in Mexico and casually in Costa Rica.
