A common puzzle facing new shorebirders is separating this species from the lesser yellowlegs. Greaters are more massive, with a proportionately bigger, slightly upturned bill, and thicker legs with pronounced "knees."
Habitat and Habits
Greaters prefer marshes, mudflats, and edges of lakes. They often forage in deeper water than other shorebirds. The call of the greater yellowlegs is different from that of the lesser yellowlegs - greaters have a louder, sharper call that is usually at least three notes, tew, tew, tew! Yellowlegs are early warning systems for other shorebirds, alerting the mudflat community to invaders.
Reproduction and Care of the Young
Breeding occurs on tundra or marshy ground in Canada and Alaska. Nests are depressions in damp ground.
