Olive-backed Foliage-gleaner
Automolus infuscatus
The olive-backed foliage-gleaner is 18 to 19 cm (7.1 to 7.5 in) long and weighs about 27 to 40 g (0.95 to 1.4 oz). It is a fairly large member of its genus and has a heavy bill. The sexes have the same plumage. Adults of the nominate subspecies A. i. infuscatus have a mostly blackish brown face with faint reddish streaks on the ear coverts and grizzled blackish brown and buff lores. Their forehead is blackish brown with wide but inconspicuous rufescent brown streaks that become faint on the dark brown crown. They have a vague dark brown collar with faint light brown streaks. Voice: The olive-backed foliage-gleaner's song is "a loud, fast, staccato, slightly descending rattle, 'tchi-r-r-r-r-r-r-r-r-r-r-r-r-r-r-r' ". Its calls include "a sharp 'chik-uh' or 'chík-wuk' " and "chik-qwaah".

Premnornis guttuliger
The rusty-winged barbtail is 13 to 14.5 cm (5.1 to 5.7 in) long and weighs 13 to 17 g (0.46 to 0.60 oz). The sexes' plumages are alike.

Their crown is dark olive-brown with a faint scallop pattern. The sides of their neck and upper back are brownish with pale buff spots, their lower back is browner and unspotted, their rump is brown with a faint rufescent tinge, and their uppertail coverts are chestnut. Voice: The rusty-winged barbtail is seldom vocal. What is thought to be its song is a fast, accelerating, "'tsi-tsi-tsi-si-si-sisisisisisi". Its call is described as a sharp "tseep" or "tsip" that sometimes runs into a series.
