This large flycatcher is extremely noisy and inhabits the canopy of riparian forest in desert areas. It hawks insects on the wing and has been know to eat hummingbirds as well. In the late summer and winter it eats more fruit. An aggressive species, it defends its territory against many other bird species. Its nest is in a natural tree cavity or old woodpecker hole in a Saguaro Cactus. The Brown-crested Flycatcher abandons its summer range earlier than most migrants, and by August has returned to Mexico.
The four-digit banding code is BCFL.
