Taczanowski's Ground Tyrant

Taczanowski's ground tyrant is 16.5 to 19 cm (6.5 to 7.5 in) long. The sexes have the same plumage. Adults have a brownish gray crown, dusky lores, a long white supercilium that extends past the eye, and a small white patch below the eye. Their nape and back are smoky gray. Their wings are a duskier smoky gray with some pale edges on the coverts. Their tail is blackish with thin white edges on the outermost feathers. Their throat is white, their breast gray, and their belly white with a buff tinge. They have a dark iris, a black bill, and black legs and feet. Voice: As of April 2025 xeno-canto had only one recording of a Taczanowski's ground tyrant vocalization and the Cornell Lab of Ornithology's Macaulay Library had none. Its song has not been described; its call is "a soft pip repeated at intervals".
