Allpahuayo Antbird
Percnostola arenarum
Scarce antbird described to science in 2001. It is found in lowland rainforest in northeastern Peru, only in areas with white, sandy soil. Male is gray with a black throat and white wingbars. Female has gray upperparts with tawny underparts and wingbars. Very similar to Black-headed Antbird, and best identified by voice, range, and habitat. Inhabits dense understory, often in areas with lots of palm saplings. Song is a fairly rapid series of ringing notes, higher-pitched and faster than the song of Black-headed Antbird.

Apurimac Brushfinch
Atlapetes forbesi
Localized red-headed sparrow-like bird. Has an ashy gray body, a rusty red head, a black face, and white lores and mustache. Forages on or near the ground in scrub and Polylepis woodlands at high elevations. Listen for a choppy series of high metallic whines, buzzy whistles, and chips.

Grass Wren
Cistothorus platensis
Tiny, bubbly, buffy-colored wren of dense grassy or shrubby habitats. Fairly common but locally distributed from central Mexico to the southernmost tip of South America; surely comprises multiple species. Occurs from open grasslands and marshes at sea level up to paramo in the high Andes. Generally secretive, but perches up when singing. Generally pale brownish with complex patterning on upperparts; compare with much plainer House Wren. Variable voice, usually including harsh chips, buzzes, and trills.

Northern Bobwhite
Colinus virginianus
Small and rotund with intricate brown, black, and white patterning. Some striking variation in plumage across range. Most males, including those in the eastern U.S., have bold black and white head pattern and heavy white spotting on belly. In Mexico, males can be entirely cinnamon-colored below and have a fully black head; some might have a white eyebrow or a dark chest band. Females are more consistent throughout range: look for buffy throat and eyebrow. Pairs or small groups are found in scrubby fields and brushy woods. Usually on the ground, but occasionally perches in trees when singing. The only quail native to the eastern U.S., where populations are declining sharply. Listen for distinctive “bob-WHITE!” whistle.
