Tyran à bec épais Tyrannus crassirostris

Large kingbird with huge bill. Rather dark grayish-brown above with white throat and pale yellow wash on belly. Overall color and bill size make this kingbird unlikely to be mistaken. Most common in riparian woodlands with cottonwood trees; often perches up conspicuously. Also occurs in other wooded habitats like thorn forest and oak scrub. Gives some squeaky calls and twitters.
