Rufous-browed Chat-Tyrant

The rufous-browed chat-tyrant is 14.5 to 16 cm (5.7 to 6.3 in) long and weighs about 14 to 15 g (0.49 to 0.53 oz). The sexes appear to have the same plumage. Adults have a brown crown and bright rufous supercilium that begins at the lores and widens past the eye. The rest of their face is dark brown. Their upperparts are brown. Their wings are dusky with rufous tips to the coverts that form one or two prominent wing bars. Their tail is dusky with white outer webs of the outermost feathers. Voice: As of June 2025 xeno-canto had no recordings of rufous-browed chat-tyrant vocalizations; the Cornell Lab of Ornithology's Macaulay Library had nine. Its dawn song is "a fast, rhythmic, duet plee, plít'ter'tew, plít'ter'tew..., chattery, up to 12 phrases slowing at end". The song has some variations such as "cháp'pa'cháp'pa or cháp'it'dip!".
