Spot-winged Antshrike

The spot-winged antshrike is 12 to 13.5 cm (4.7 to 5.3 in) long and weighs 23 to 27 g (0.81 to 0.95 oz). It has a short tail and a heavy bill. The sexes have quite different plumage. Adult males of the nominate subspecies are mostly gray that is somewhat darker on their upperside, with a black crown, scattered black feathers on their back, and white spots on their wing coverts. Adult females are gray with a clay tinge on the crown, upperparts, tertials, and tail. Their face and underparts are pale clay with a gray tinge on the flanks and undertail coverts. Voice: The spot-winged antshrike's song is a "rather short...uncountable series of evenly spaced abrupt notes, increasing in intensity and declining slightly in pitch, immediately followed by long whistle usually rising and falling slightly in pitch". It has been rendered as "tdrrrr Tiúw" and "t-t-t-t-t-t-teéuw". Its calls include a sharp "'chet!" or "chak".
