Stocky brown wader with bright red legs; compare with slenderer, far more gracile Spotted Redshank in juvenile and non-breeding plumage. Often rather wary, alerting other birds with its loud, fluty, whistled calls. Bobs tail when nervous, and then flies to show flashy white trailing edge to wings, white rump patch. Feeds in muddy shallows, probing and picking with its bill. Inhabits fresh and coastal wetlands; also breeds locally on moorland, usually near water. Migrant and winter flocks of hundreds occur locally on tidal mudflats.
