Boldly patterned tiny bird, usually found in groups in open montane forest. Adult gray above, pale below, with vivid rufous crown, black throat and mask separated by white, chestnut-washed flanks, and yellow eye. Juvenile has gray rather than orange and lacks black on the throat. Forages acrobatically in small branches, sometimes hovering at the tips to extract invertebrates. Often difficult to see in dense trees; presence given away by high-pitched contact calls (“tsip”) and thin, rolling trills.
