In flight, it makes a series of 3 to 5 whistling calls. Its bill tends to turn up slightly. Its bright yellow legs are more strongly jointed than are those of the lesser yellowlegs, which is also a smaller bird. The male and female are similar in appearance. Reproduction These birds are probably monogamous. The nest is built on the ground, in a bog, and set apart from others. The female usually lays 4 eggs. Both parents incubate the eggs, for 23 days, and care for the young. The young are precocial, meaning that they can feed themselves as soon as they are hatched, and fly at 3 weeks. Diet They eat small fish and aquatic and land insects. They also eat larvae, snails, worms, tadpoles and berries. Predators Hunting caused a major decline in many species of shorebirds, including these, before they were protected under the Migratory Birds Convention Act. Habitat During the breeding period, they live in the boreal forest in Alaska and Canada. In Québec, they frequent mainly boggy, wooded areas in the centre of the province. They winter along the Atlantic and Pacific coasts. They are found as far away as the southern tip of South America. Ecology, behaviour The greater yellowlegs is shyer and less gregarious than the lesser yellowlegs.
