Ash-throated Antwren

The ash-throated antwren is 11.5 to 13 cm (4.5 to 5.1 in) long; the holotype weighed 11.5 g (0.41 oz). Adult males have a black crown, a pale grayish white supercilium, a black streak through the eye, and pale grayish white ear coverts. Their back and rump are gray with dark gray to black scapulars that have wide white outer webs. They have a mixed black and white patch between the scapulars. Their wings are black with wide white tips on the coverts and brownish tips and white outer edges on the flight feathers. Voice: The ash-throated antwren's song is "a rapid, accelerating-decelerating, rising-falling series of rich notes, with a rising series of 2 or 3 introductory notes: pew-PEW-PEW-pee'e'E'E'E'e'e-e-e-e-u". Its call is "a rich, short tchew, often doubled or tripled".
