Tyranneau à flancs roux Euscarthmus rufomarginatus

Tiny flycatcher with a long tail. Note the white throat contrasting with the brown back, yellowish belly, and cinnamon flanks. Occurs in open, well-preserved natural grasslands with scattered bushes. Has a distinct song, a series of repetitious fast buzzy notes: “tic, tic, tic, tiker-trrrrrk.”
