Species of bird

The greater yellowlegs (Tringa melanoleuca) is a large shorebird in the family Scolopacidae. It breeds in central Canada and southern Alaska and winters in southern North America, Central America, the West Indies and South America.

The greater yellowlegs was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Scolopax and coined the binomial name Scolopax melanoleuca. Gmelin based his description on the "stone snipe" seen feeding in autumn in Chateau Bay, Labrador, that had been described in 1785 by both the English ornithologist John Latham and by the Welsh naturalist Thomas Pennant. The greater yellowlegs is now placed in the genus Tringa that was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. The name Tringa is the Neo Latin word given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek trungas, a thrush sized, white rumped, tail bobbing wading bird mentioned by Aristotle. The specific epithet melanoleuca combines the Ancient Greek melas meaning "yellow" with leucos meaning "white". The species is monotypic: no subspecies are recognised. The call is harsher, louder, and clearer than that of the lesser yellowlegs. They have a three syllable whistle when flight calling, with a lower pitched third syllable.

Their breeding habitat is bogs and marshes in the boreal forest region of Canada and Alaska. They migrate to the Atlantic and Pacific coasts of the United States, the Caribbean, and south to South America. They are very rare vagrants to western Europe.

These birds forage in shallow water, sometimes using their bills to stir up the water. They mainly eat insects and small fish, as well as crustaceans, marine worms, frogs, seeds and berries.
