Dusky-tailed Antbird

A small mostly gray tapaculo with brown and rusty streaks on the belly and vent. The tail is short and usually held cocked. Inhabits rocky and shrubby areas at high elevations where it forages by hopping on the ground. The song is a long and repeated series of “chip-chip-chip” notes.

Nondescript warbler, generally olive-colored overall, but different populations vary from grayer to brighter yellow. Overall very plain and unmarked, but note short darkish line through eye and thin pale eye arcs. Forages for insects in scrubby areas, woodland edge, and thickets. Namesake orange crown is very difficult to see, and usually only a faint wash at best. More common in western North America, from Alaska to Mexico, where populations are brighter yellow-green. Birds in eastern North America are scarcer and drabber, often with a more contrasting grayish head. Bright yellow undertail coverts help separate Orange-crowned from the similarly drab Tennessee Warbler.

A small hummingbird with a straight red bill with a black tip. Males have a green back with iridescent violet-blue underparts, a coppery tail, and a fluffy white vent. Females have grayish dark underparts with some dark spots on the chest. Note the rufous chin in both sexes, which can be hard to see. Mostly found in humid forests and wooded savannas.
