The Sulphury Flycatcher (Tyrannopsis sulphurea) is found in Trinidad, the Guianas, and other parts of South America.
The head and neck of the adult sulphury flycatcher are dark grey, and there is a concealed yellow crown stripe. The upperparts are olive, and the wings and tail are brown. The underparts are yellow with a greenish tint to the upper breast and a white throat. The black bill is short and broad.
Sulphury flycatchers wait on an exposed perch high in a palm and catch insects in flight. They will also take some berries.
