A stone-colored terrestrial bird of stony hillsides, mountain ridges, and meadows above treeline. Adults speckled gray and white above, with dense rusty streaking on white underparts, red bill, and deep red legs. Usually forages in small groups, often in very exposed areas such as cliff sides and rocky ridges. Song, often given by multiple birds in a group simultaneously, is high-pitched and has a slippery, squeaky quality like wet shoes on tile; male song louder and ascending, female’s softer and descending.
