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".

Social Flycatcher
Myiozetetes similis
The social flycatcher is 16 to 18.5 cm (6.3 to 7.3 in) long and weighs 24 to 27 g (0.85 to 0.95 oz). The sexes have the same plumage, though females average slightly smaller than males. Adults of the nominate subspecies M. s. similis have a dark gray to brownish gray head with a mostly hidden bright red to orangish red patch in the center of the crown. They have a wide white supercilium that begins on the forehead and extends far past the eye. Voice: What is thought to be the social flycatcher's dawn song is a "shrill note repeated several times, sometimes followed by longer and continuously repeated series, seeu, seeu, see-u-chú, sree, sree, sree si-si-chuhr, or shorter but still repeated chirrrr". It also makes "a shrill and piercing seeá, tcheiit or see-yh!
