Small flycatcher of rainforest canopy. Dull greenish yellow, with brighter yellow wing edging and a grayish head. Subtle black eyeline with white arcs above and below the eye create a faint facial pattern. Compared to the similar Gray-crowned Flycatcher, is smaller, with much smaller bill, and often has a dark eye. Listen for its song, a short accelerating series of musical notes, and its call, a liquid “duit” similar to the calls of several other species, like Dwarf Tyrant-Manakin.
