Piratic flycatcher

The piratic flycatcher is 14.5 to 17 cm (5.7 to 6.7 in) long and weighs 19 to 26 g (0.67 to 0.92 oz). The sexes and the subspecies have the same plumage though subspecies L. l. variegatus is significantly larger than the nominate. Adults have a blackish forehead and crown with a partially hidden yellow patch on the latter. They have a wide dull whitish supercilium that extends around the head under the crown; it has some faint grayish streaks toward the rear. They have dusky lores, ear coverts, and moustachial stripe and white cheeks. Their upperparts are mostly dark grayish brown or dark olive-brown with pale edges on most feathers. Their uppertail coverts have rusty or cinnamon edges. Their wings are brownish black with whitish edges on the coverts. Their primaries have very thin pale grayish brown edges and their secondaries have whitish edges. Their tail is dusky brown or blackish brown. The tail feathers' inner webs and sometimes the outer webs have lighter edges. Their chin and throat are unstreaked whitish. Their underparts are mostly yellowish white or pale yellow with wide brownish or olive streaks on the breast, sides, and flanks. Their short, wide, and stubby bill is mostly brownish black with a browner base to the mandible. They have a brown iris and dusky legs and feet. Juveniles have no yellow on the crown. They have light cinnamon tips on the crown feathers, a buffy supercilium, wide cinnamon edges on the wing coverts, rusty edges on the tail feathers, and paler underparts than adults with few or no streaks.
