The Western Kingbird range is mostly West of the Missouri River. It prefers open country and is often seen perched on roadside fences and wires where it can sally out to snatch up insects or to harass ravens, hawks, or other large birds.
It feeds mostly on insects like wasps, bees, beetles, and grasshoppers. But will also eat berries and fruits.
It is well adjusted to farmlands and ranches and can even be found in small towns on occasions.
