Myiobius sulphureipygius (Sclater, PL, 1857)

This flycatcher measures 12 cm (4.7 in). It has an olive-brown head and upper back, blackish wings and tail, and a tawny breast and sides. The face and eye ring are grey while the throat is whitish. The namesake rump patch is light yellow and extends to the mid-back. The belly is also yellow, as is a small crest.^[3]

Often found near streams, the sulphur-rumped myiobius participates in mixed-species flocks that move through the lower levels of the forest.

This bird often displays its rump patch by fanning its tail and dropping its wings. Its call is a sharp psit.^[3]
