Muisca Antpitta
Grallaria rufula
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 Muisca antpitta is about 14 to 15 cm (5.5 to 5.9 in) long; four individuals weighed 32 to 36 g (1.1 to 1.3 oz). The sexes have the same plumage. Adults have rufous brown upperparts that are a slightly brighter rufous on their face, throat, and breast. Their underparts are mostly rufous brown with dark grayish rufous flanks, a paler rufous central belly, and white or buffy white lower belly and vent. Voice: The Muisca antpitta's long song is "a drawn out series of clear whistles with a slightly clipped sound...lasting a total of ~6–11 seconds" and accelerates at the end. It also has a short song, "a thin, clear whistle lasting ~0.75 s...followed by a pause and then a lower, fast liquid trill of about the same length".

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".
