Call of the Black Solitaire is a weak, slightly buzzing tzeeeeeeee or weeeeenh, lasting 1-2 sec, ventriloquial and hard to locate in the dense cover that the species prefers. The song is a weak but far-carrying, high, buzzy, nasal weeeeeenh, a bit longer than 1 sec. This song is very similar to that of congener White-eared Solitaire (E. leucotis). Song of the Black Solitaire is heard very infrequently.
Additional recordings of the vocalizations of the Black Solitaire can be heard at xeno-canto.
