The greater yellowlegs ( Tringa melanoleuca ) is a large North American shorebird. The genus name Tringa is the New Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas , a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific melanoleuca is from Ancient Greek melas , "black", and leukos , "white".
