Family: Tyrannidae, Tyrant Flycatchers view all from this family

Description 5 1/4-6 1/2" (13-16.5 cm). A very small, gray-green to olive-brown bird with prominent light wingbars. Whitish to pale olive to yellowish below. Faint to no pale eye-ring. Lower bill light yellow to orange.

Endangered Status The Southwestern Willow Flycatcher, a subspecies of the Willow Flycatcher, is on the U.S. Endangered Species List. It is classified as endangered in Arizona, California, Colorado, New Mexico, Texas, and Utah. Destruction of the dense streamside thickets that it nests in has dealt a serious blow to this species. Another problem has been nest parasitism by cowbirds, which lay their own eggs in the flycatchers' nests, to the detriment of the flycatchers' own broods. Predators, especially those that feed on eggs, have also contributed to this small bird's decline.

Habitat Dense streamside thickets and woodlands.

Range Breeds in southwestern United States, locally from California to Texas. Winters in Mexico and southward.
