Bicolored Antpitta
Grallaria rufocinerea
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 bicolored antpitta is 15 to 18 cm (5.9 to 7.1 in) long; one individual weighed 44.8 g (1.6 oz). The sexes have the same plumage. Adults have a mostly rufous-brown or ferruginous red head, throat, upperparts, wings, and tail, though the throat is slightly more rufous than the rest and has some grayish mottling. Their underparts are mostly gray to sooty gray with a whitish central belly and whitish edges on the breast, side, and flank feathers. Voice: The male bicolored antpitta sings "a high, clear, whistled treeeee or treeeeeuh". Females apparently answer with "a kree-kree-kree-kree-kree-kree".

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).
