Plumbeous Antbird
Myrmelastes hyperythrus
The plumbeous antbird is 17 to 18 cm (6.7 to 7.1 in) long and weighs 38 to 44 g (1.3 to 1.6 oz). Males are mostly dark slaty gray. Their wings and tail are blackish gray with white spots at the tips of the wing coverts. They have a large area of bare light blue skin around their eye. Females have dark slaty gray upperparts, wings, and tail like males. Their underparts are bright rufous with a brown tinge on their flanks and crissum. Voice: The plumbeous antbird's song is "a long...rattling trill that accelerates throughout, and gains and then declines in intensity". It has been written as "wo-wu-wu-wu-wu-wu-wu-wrrrrrrrrrr" and "wur-wur-wurwrwrwe'e'e'e'e'ip". Its calls include "wo-púr" or "klo-kú" and "a fast chattering 'chrr-trr-trr-trr-trr-trr-trr' ".

Myrmorchilus strigilatus
The stripe-backed antbird is 15 to 16 cm (5.9 to 6.3 in) long and weighs 23 to 26 g (0.81 to 0.92 oz). Adult males of the nominate subspecies have a white supercilium and a dark line through the eye on an otherwise buffy face. Their crown, neck, and back are rufous with black streaks; their rump and uppertail coverts are plain rufous. Their central tail feathers are rufous and the outer ones black with white outer edges and tips. Their wings are black with some rufous on the edges of the flight feathers; their wing coverts are black with white tips. Their throat and breast are black. Voice: The two subspecies of the stripe-backed antbird appear to have the same song. It is a "ery/extr. high, sharp 'sreet-soweét' " that is sometimes followed by a "strident, slightly descending 'sreet-sreet-sreet-sruw-sruw' ". The species' call is "a long...whistle, entirely downslurred or slightly rising and falling".
