Voice: The crowned slaty flycatcher is fairly quiet during the breeding season and usually silent in its winter range. Its song is a "thin buzzy and rising be-bee-beee-beeez, low whistling pree-ee-ee-er, and a series of squeaky notes, or a two part tsi-tsitsewt-tsi-tsébidit phrase".

Empidonomus varius
The variegated flycatcher is 18 to 19 cm (7.1 to 7.5 in) long and weighs about 25 g (0.88 oz). The sexes have the same plumage. Adults of the nominate subspecies have a blackish or blackish brown crown with a mostly hidden yellow patch in the center, a long white supercilium that extends almost around the nape, a wide dusky band from the lores to the ear coverts, and whitish cheeks with a dusky band below them. Their upperparts are mostly dusky or dark brownish with pale whitish streaks that give a mottled appearance. Voice: The variegated flycatcher is usually rather quiet. It makes a "harsh "chee-chee-chu" call" whose last note is dragged out and also weak "high-pitched, thin and nasal pseee, zureee or zreeetee" calls, sometimes in a series. In Brazil it makes a "ver/extr. high, thin feeee-io" call.
