The Yellow-breasted Flycatcher (Tolmomyias flaviventris) is distributed, in a wide variety of forest types, across much of northern and central South America, from northern Colombia and Venezuela, as well as in Trinidad and Tobago, south to the Atlantic coastal forests of eastern Brazil.
The head and upperparts are olive-green with darker, yellow-edged, wing and tail feathers. There are two yellowish wing bars. The throat, breast and eye-ring are golden yellow, the lores are ochreous, and the abdomen is dull yellow. The bill is flattened laterally, and is black above and white below. Sexes are similar. There are other races, differing in the tone of the upperpart or underpart colour.
