Saturnine Antshrike

The saturnine antshrike is 13.5 to 14.5 cm (5.3 to 5.7 in) long and weighs 19 to 21 g (0.67 to 0.74 oz). Adult males of the nominate subspecies have darkish gray upperparts with a white patch between their scapulars. Their wings are darkish gray with white edges to feathers at the bend and white tips on the coverts. Their tail is darkish gray with small white tips on the feathers. Their throat and upper breast are black and the rest of their underparts darkish gray with usually some white edges on the belly feathers. Adult females have olive-brown upperparts with a rufescent tinge. Voice: The saturnine antshrike's song is an "accelerated, ascending series of notes, at first grating, then gradually changing to sharp and piercing". Its calls include a "short 'chirr' ", a "downslurred rasp", and an "abrupt, clearer note".
