Grauscheitel-Olivtyrann Suiriri suiriri

Small flycatcher with a gray head, an olive-brown back, a dark tail, and two grayish wingbars. Subspecies vary in the colour of rump (yellowish or brown) and belly (pale yellow or white). The similar Chapada Flycatcher has a white rump, a yellow belly, a broad whitish tail tip, and a different song and display. Inhabits savanna-like areas with scattered trees and bushes. The song is an easily recognizable series of “pi-chew” notes.
