The Lesser Yellowlegs is a medium-sized shorebird similar in appearance to the larger Greater Yellowlegs. Their breeding habitat is clearings near ponds in the boreal forest region from Alaska to Quebec. They nest on the ground, usually in open dry locations.
They migrate to the Gulf coast of the United States and south to South America. 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.
