Ochre-faced Tody-Flycatcher
Poecilotriccus plumbeiceps
The ochre-faced tody-flycatcher is 9 to 10 cm (3.5 to 3.9 in) long and weighs 5.3 to 6 g (0.19 to 0.21 oz). The sexes have the same plumage. Adults of the nominate subspecies P. p. plumbeiceps have a buffish cinnamon forehead and a gray crown. Their face is mostly buffish cinnamon with dusky ear coverts. Their back, rump, and uppertail coverts are dark olive. Their wings are dusky with ochraceous edges on the flight feathers and tips on the coverts; the latter show as two wing bars. Their tail is dark olive. Their throat is a slightly paler buffish cinnamon than the face. Voice: What could be either the call or song of the ochre-faced tody-flycatcher in Brazil is a "very fast 'prrrrrur' rattle (1 or 2 x, 2nd time slightly lower)". In Peru its song is described as "a deep, rich sputtering trill: tjrrp-tjrrrrrrr'rrr'rrp or simply tjrrrrp" and its call "a quiet rich tchup".

Rufous-crowned Tody-Flycatcher
Poecilotriccus ruficeps
The rufous-crowned tody-flycatcher is about 9 to 10 cm (3.5 to 3.9 in) long and weighs about 6.6 g (0.23 oz). The sexes have the same plumage. Adults of the nominate subspecies P. r. ruficeps have a bright rufous crown and a gray nape that are separated by a black line that continues onto the cheek. They have a white to buffy area above the lores, a thin black line through the eye, and white to buffy cheeks. Their back, rump, and uppertail coverts are olive. Voice: The rufous-crowned tody-flycatcher's vocalizations are "soft, easily overlooked, and usually given only at well-spaced intervals". Its song has been described as a sputtering "pa-treer-pít-pít-pít" with some variation. Its calls include "a gravelly stuttered 'tttrew', 'pit-tttrew', or 'tttrew-pit', sometimes given as a duet".
