The black-chinned antbird is 11 to 12.2 cm (4.3 to 4.8 in) long and weighs about 12 to 18 g (0.42 to 0.63 oz). Adult males have leaden gray upperparts. Their tail is slate gray with narrow white feather tips. Their flight feathers are leaden gray with lighter gray edges and their wing coverts are black with gray and white edges. Their throat is black. Their underparts are mostly a paler gray than their upperparts and with a grayish white belly. Adult females have the same leaden upperparts as males. Their throat is whitish with black and gray speckles. Voice: One description of the black-chinned antbird's song is "an accelerating, rising series of modulated, rising whistles that descends slightly at the end with much more buzzy notes: whee wee-wee'wee'wi'wi'wiwiwidz'dz'dzee". Another description is a "series of 8-12 high, accentuated 'few' notes, 1st 2-3 evenly-spaced and rising, then as 'djew' notes accelerating and bouncing down".
