Tiny, plump flycatcher found in the understory of the subtropical zone in the Andes, especially around bamboo. Distinctive plumage with yellow belly, white throat, rufous crown, black border around cheek, and bold yellow wingbars. Some populations show rufous wash on cheeks and a reduced black border. Sexes similar. Usually seen in singles or pairs, inconspicuously flitting around the understory of forest and edge. Listen for stuttering calls.
