Grallaria milleri
The brown-banded antpitta is 13 to 18 cm (5.1 to 7.1 in) long and weighs about 50 to 55 g (1.8 to 1.9 oz). The sexes have the same plumage. Adults have whitish lores with black speckles. Their ear coverts are ochraceous brown. Their crown, nape, back, and uppertail coverts are deep rich raw umber and their rump slightly paler. Their tail can be more rufescent or slightly more greenish than their back. Their wings are generally similar to their tail with dusky brown primaries and raw umber coverts. Their throat is grayish white with tawny olive sides. Voice: The brown-banded antpitta's song is a "single upslurred uuueee"; it also makes a "3-note tu, tu-tu". Its call is a "single loud shrill note KEEEE" given in a series. The species sings at any time of the year, mostly during the morning, and typically from a low perch in dense undergrowth.

Plain-backed Antpitta
Grallaria haplonota
Grallaria antpittas are a "wonderful group of plump and round antbirds whose feathers are often fluffed up...they have stout bills very short tails". The plain-backed antpitta is 16 to 17 cm (6.3 to 6.7 in) long and weighs 75 to 90 g (2.6 to 3.2 oz). The sexes have the same plumage. Adults of the nominate subspecies G. h. haplonota have a pale buff "moustache" with a dusky stripe below it on an otherwise brown face. Their upperparts are brown with a gray tinge on their crown; their tail is dark rufescent. Voice: The plain-backed antpitta sings from the ground or a low perch. Its song has been described as "a slow, measured of ca. 5-9 low, hollow notes rising slightly in middle" and as "a fairly slow, slightly decelerating, rising-falling, loudest at the highest pitch, series of hooted notes".
