Equatorial Antpitta
Grallaria saturata
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 equatorial antpitta is about 14.5 to 15 cm (5.7 to 5.9 in) long and weighs 32 to 47 g (1.1 to 1.7 oz). The sexes have the same plumage. Adults have mostly rufous-brown upperparts; the sides of their head are somewhat more rufous. Their underparts are also mostly more rufous than their upperparts, with dark gray-brown flanks, a light rufous center to the belly, a buffy white to white vent, and whitish undertail coverts. Voice: The equatorial antpitta's long song is "a rapid, slightly descending trill of short, ringing notes lasting ~1.5–3.5 ". Its short song "begins with a single clear note, followed by a brief pause and then a fast, accelerating but stuttering trill of 4–5 notes". It apparently sings mostly at dawn and from a low perch.
