Adults have a faint grayish supercilium on an otherwise brown face. Their upperparts are also brown. Their wings are mostly blackish with rufous basal halves on the flight feathers' inner webs and buff edges on the secondaries; the rufous shows as two wing bars. Their tail is mostly blackish with pale cinnamon outer webs on the outermost pair of feathers and pale cinnamon edges on the inner webs of the other pairs. Voice: The rufous-bellied bush tyrant's song is "a vigorous pip-pip-pip pi-DOO"; the number of pip notes varies from two to four and the pi-DOO is sometimes repeated once. The species' call is "a rising-falling series of rich pip notes".
