The Greater Yellowlegs is a large North American shorebird, similar in appearance to the smaller Lesser Yellowlegs. Adults have long yellow legs and a long, thin, dark bill which has a slight upward curve and is longer than the head. The body is grey-brown on top and white underneath; the neck and breast are streaked with dark brown.
Fun Fact Although the Greater Yellowlegs is common and widespread, its low densities and tendency to breed in inhospitable, mosquito-ridden muskegs make it one of the least-studied shorebirds on the continent.
