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".

Grallaria hypoleuca
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 white-bellied antpitta is 16 to 18 cm (6.3 to 7.1 in) long; three males weighed 62 to 69 g (2.2 to 2.4 oz). The sexes have the same plumage. Adults of the nominate subspecies G. h. hypoleuca have a rufescent brown or dusky brown crown with some black streaks on the forecrown. They have white or gray lores on a rufous face. Their back, rump, wings, and tail are reddish brown. Their throat is white. Voice: The white-bellied antpitta's "simple and far-carrying song a fast too, téw-téw, given at rather long intervals (often 10 or more seconds)".
