A handsomely-marked medium-sized gray shorebird with a medium-length, straight bill. Similar to Wandering Tattler; note wider white eyebrows that meet on the forehead above the bill, shorter nasal groove (only visible at close range), and finer and paler barring on the underparts (present only in the breeding season) that do not usually extend to the undertail coverts. Breeds near water in taiga and tundra, and frequents reefs, mangroves, mudflats, and beaches on migration and during the non-breeding season. Most common call is a two-note “too-lee,” but also gives trills similar to those of Wandering, especially when alarmed.
