Cassin Kingbird

On arid rocky hills CASSIN KINGBIRDS sit quietly on tree tops until insect prey sends them skyrocketing. Often these wild sky dances are not induced by pursuit but seem to be executed by a sudden spasm of internal energy. Their normal behavior is more quiet than the Arkansas Kingbird but at evening they make the valley echo with loud, almost martial, calls.

Range

Western North America from Central California east to Wyoming, Colorado and western Texas.
