Upland Antshrike is a resident of the lower slopes of the Andes of extreme southeastern Peru and northwestern Bolivia. Males are primarily gray with a blackish crown, wings and tail; the wing coverts and rectrices have white tips, and the posterior underparts are faintly barred. Females are quite different; they are mostly olive brown, paler and buffier below, with a rufous crown and grayish ear coverts. Upland Antshrike occupies montane evergreen forest edge and second growth forest, where it is typically found in dense thickets of bamboo. Rarely found more than 30 meters from the forest edge, these birds feed on insects in dense large leaved bushes no more than 6 meters above the ground. Foraging behavior consists of vertical sally-gleaning to the underside of tree trunks and bamboo leaves as wells as searching through dead bamboo and leaves trapped in thickets. Otherwise very little is known about the natural history of Upland Antshrike.
