stout-billed cinclodes Cinclodes excelsior

Bold, terrestrial bird of high Andean grasslands and pastures. Mostly brown with white throat, white eyebrows, and chestnut patches in the wings. Larger overall with a longer, thicker, and more curved bill than the otherwise similar Chestnut-winged Cinclodes. Feeds on the ground, darting back and forth while chasing prey; often rests on posts, rocks, tussocks, and other exposed perches. Song is a quick, rising trill.
