Appearance:

The pointed crest makes it rather unmistakable, but can be overlooked if crest is folded. Brown upperparts, pale buff underparts and black bib. Speckled crown and black eye-stripe connecting to characteristic cheek markings.

Sound:

Call a characteristic vibrating rolling trill "Trrrrurrrurrrit", with last syllable emphasized and ending with ascending pitch. Often preceded by a couple of introductory "tzi tzi". Song: an improvisation over previously described calls.
