Spitzschwanz-Grastyrann Culicivora caudacuta

A handsome tiny flycatcher with a long spiky tail. Note the conspicuous broad white eyebrow and white chin. It has black-and-brown streaking down its back and rusty sides. Inhabits tall grasslands in the lowlands that are rarely disturbed; can be hard to spot in the tall vegetation. Not very vocal; the song is a series of weak and short “tweee tweee tweee” notes.
