Dusky-chested Flycatcher
Myiozetetes luteiventris
The dusky-chested flycatcher is the smallest member of genus Myiozetetes. It is 14 to 15 cm (5.5 to 5.9 in) long and weighs about 16.5 g (0.58 oz). The sexes have almost the same plumage. Adult males of the nominate subspecies have a grayish olive-brown crown and face with a mostly hidden yellow-orange patch in the center of the crown. Females have a smaller patch or none at all. Adults of both sexes have dark olive-brown upperparts. Their wings are dark olive-brown with faint and variable rufous edges on the flight feathers. Their throat is whitish with faint dusky streaks. Voice: The dusky-chested flycatcher's most common call is "a nasal, cat-like meeow or softer neea". It makes a "fast nasal nyeeuw-nyeeuw, keep-kít or neea-ne-wít" when it is excited; sometimes pairs do this in duet. It also makes simple, often repeated, "keeuw or nyeeuw" calls.

Grey-capped Flycatcher
Myiozetetes granadensis
The grey-capped flycatcher is 16 to 18 cm (6.3 to 7.1 in) long and weighs 28 to 30 g (0.99 to 1.1 oz). The sexes have almost the same plumage. Adult males of the nominate subspecies have a gray crown and nape with a mostly hidden orange-yellow to reddish orange patch in the center of the crown. Females sometimes have a smaller patch or none at all. Adults of both sexes have a white forehead that extends as a thin supercilium to just past the eye. They have dusky lores and ear coverts. Their upperparts are mostly olive-green with dusky to dark olive uppertail coverts that have paler edges. Voice: The grey-capped flycatcher's vocalizations appear to vary somewhat across its range. In Ecuador west of the Andes its dawn song is a "kip, ki[p, kip, keeuw-kreh" that lasts about two or three seconds. East of the Andes it sings "a faster kip, kip, kip, kip, kip, kip, ke-ke-kree-yí" that lasts one or two seconds. Its Central American song is written as a "high djup-djup sréeeh".
