Worstbird

Small earthcreeper with long tail and curved bill. Inhabits the ground and low vegetation in dense Chaco spiny woodlands and shrubby slopes, where it generally forages alone. Both sexes have uniform orangish-brown plumage. Note the white throat and the dark supercilium. Feeds on small insects and caterpillars gleaned out of the ground. Voice is a series of 5–10 loud notes increasing in volume.

A squat and rotund bush-quail. Males have a dull chestnut forecrown and face, a thin white eyebrow over a dark brown eyeline that broadens behind the eye. Lightly barred brown above and boldly barred in black and white below. Females have a similar but duller head pattern with vinaceous underparts without barring. Note the slaty gray bill and orange legs. Found in pairs or family groups in dry rocky areas with scrub. Secretive, but its musical trill followed by rapidly ascending piping notes is often heard.

Rather large, dull-plumaged hummingbird of humid tropical lowlands. Favors forest edge and adjacent clearings with trees, flowering bushes, and gardens. Best field marks are its large size and big white tail corners. Sexes look alike: dull greenish overall with medium-length, straightish black bill, dingy buffy belly, and white spot behind eye (like many hummingbirds). Breast is vaguely mottled and not obviously scaly.

Boldly patterned wren with a localized range in southern Peru. Reddish brown, with a black-and-white streaked face and breast and a bold white eyebrow. Larger and longer-tailed than the similar Gray-breasted Wood-Wren. Found in dense undergrowth of humid montane forest, often in bamboo thickets. Listen for its rollicking whistled song, usually given in duet.

Minute woodpecker of lowland and foothill forests, where it forages in areas with dense low vegetation at the lower and middle levels. Predominantly rusty orange, with an olive-green crown and wings and a small but bright white eyebrow; the very similar Rufous Piculet lacks a pale brow. Male White-broweds have a bright yellow patch on the forehead which females lack. Often solitary, but can be found in small flocks and mixed-species foraging groups. Gives an explosive, squeaky, often descending chatter and sharp “chip” notes.
