A small, very dark brown shorebird with a very short thin bill and a distinct white eyebrow. Upperparts spotted with buff, underside spotted or barred with brown. Legs yellow or grayish. In flight, looks very dark with very rounded wings. Prefers coastal shoreline and bare gravel of tiny atolls. Combination of odd proportions, very short thin bill, and white eyebrow should make this species unmistakable. Most common call is a nasal “kek,” but when excited gives a loud piping whistle and a series of rising and falling trills.
