Moustached Antpitta
Grallaria alleni
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 moustached antpitta is 16.5 to 17 cm (6.5 to 6.7 in) long; two males weighed 64 and 77 g (2.3 and 2.7 oz). The sexes have the same plumage. Adults of the nominate subspecies have a light olive brown forecrown and a slate gray crown and nape with thin blackish edges on the feathers. They have white lores, olive brown ear coverts, and a wide white "moustache" with thin black streaks in it. Voice: The moustached antpitta's song is "a slightly ascending series of hollow notes that gradually become louder; higher pitched and slower paced than Scaled Antpitta's song" (which see here).

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".
