Thick-billed Kingbird

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.

识别特征

This is a large tyrant flycatcher, with adults measuring 23.5 cm (9.3 in) in length. Adults are dusky olive-brown on the upperparts with light underparts; they have a long dark brown or black tail. The underside is a dull white to pale yellow. They have a yellow patch on their crown, but is not visible very often. The bill on this species, for which it is named, is rather large and stocky compared to other members of this group and it is one of this kingbird's most distinguishing characteristics. The call is a loud, whistled pwaareeet.

分布与栖息地

This bird breeds from southeastern Arizona and extreme southwestern New Mexico in the United States and northern Sonora (the Madrean sky islands) through the western and western-coastal ranges in Mexico, south to western Guatemala. Thick-billed kingbirds usually occur in arid or partly arid areas in streamside riparian canyons, or open areas near water. They are particularly fond of sycamore woodland edges.
