Adults have long yellow legs and a long thin dark bill, about the same length as the head. The body is grey brown on top and white underneath; the neck and breast are streaked with dark brown. The tail is white.
This species is a regular vagrant to western Europe, and the odd bird has wintered in Great Britain.
These birds forage in shallow water, sometimes using their bill to stir up the water. They mainly eat insects, small fish and crustaceans.
The call of this bird is softer than that of the Greater Yellowlegs.
