Dubois's Seedeater

Rather nondescript vireo with a blank face. Pale grayish-olive overall with a faint white eyebrow, darker grayish crown, and pale yellowish wash on the sides. Often confused with Philadelphia Vireo; note Warbling shows brightest color on sides (not throat) and fainter dark eyeline (especially indistinct in front of the eye). Warbling is also longer-tailed and has a slightly longer, thinner bill than Philadelphia. Scratchy warbling song is heard from treetops, particularly in riparian areas and cottonwoods. Migrants and wintering birds can be found in any wooded habitat, as far south as Central America.

Unique, medium-sized antbird with a spectacular heavy and markedly upturned bill. Male is slate gray with a black throat, breast, and tail, and black dotted wings. Female is chestnut with a darker tail and buffy spotted wings. Rare, local, and hard to see, typically skulking in the dark understory of second growth and mature forest in foothills, often in areas with dense bamboo. Best found by voice; song a series of short notes accelerating “deeu-deee-dee-dee-eet-et.”

Very small finchlike bird with a robust bill with obviously curved mandibles. Males are mostly gray with a paler belly and a yellow bill. Females are olive-brown above and pale below with a black bill. Found at the forest edge and in second growth where it is largely dependent on bamboo patches.
