This small vireo is the only member of the genus Tunchiornis and is widespread from southern Mexico through much of the Amazonian and Guianan regions. It frequently joins mixed-species flocks, where it glean-insects meticulously from foliage and vine tangles. The warm tawny crown that gives it its name is often subtle and best seen in good light.

short rapid wingbeats with quick flits through foliage
Social Behavior
Often found in pairs or small family groups and regularly joins mixed-species flocks moving through the understory and midstory. Likely monogamous, building a neat cup nest suspended from thin branches or vines. Both adults typically participate in parental care.
