Dark, rusty-brown bird of shady forest floors in humid evergreen forest of tropical foothills and highlands; often near gullies and streambeds, where digs its nest burrow into earth banks. Feeds by tossing leaves on the forest floor. Mostly seen as it flushes, when it flies off with loud “skweek” calls. Note the long slender bill, rich rusty throat and breast, and dark rusty rump. Listen for descending series of squeaky whistles. Widespread across much of South America, to southeast Brazil.
