Cinereous Antshrike

The cinereous antshrike is 14 to 15 cm (5.5 to 5.9 in) long and weighs 16 to 18 g (0.56 to 0.63 oz). Adult males of the nominate subspecies T. c. caesius are almost entirely dark gray; the inner edges of their secondaries and their underwing coverts are white. Adult females have olive-brown upperparts with a small white patch between the scapulars. Their wings and tail are olive-brown with a rufous tinge. Their throat is buff, their breast, sides and flanks olive with a tawny-cinnamon tinge, and the center of their belly and their crissum tawny-cinnamon. Voice: The cinereous antshrike's song is a "series, starting with some slow, sharply rising notes, then descending as a short rattle". It has been rendered as "whee? whee? whee? whee-whee-whee-wheep-wheep-whip-whipwhip-p-p-p-p-p-p-prrrrr". Its calls include "a staccato 'wer-chicory' " and "wu-chidididik".
