Large yellow-bellied flycatcher with gray head, greenish back, and brownish wings and tail. Relatively long bill. Nearly identical to Couch's Kingbird and very similar to other yellow-bellied kingbirds. Distinguished from Couch's Kingbird by voice: sharp twitters, not just single "pick" or "breer" calls. Larger and longer-billed than Western and Cassin's Kingbirds; also note paler brownish tail. Prefers open areas with some trees and water, but also parks and neighborhoods.
