Pluvialis dominica is a medium-sized bird (22 cm) that makes one of the longest migratory journeys of any shorebird. Their diet consists mainly of insects, worms, crustaceans and other invertebrates. They will also supplement their diet with berries, seeds, and occasionally grass. In Uruguay they are usually found in thhe native grasslands surrounding the coastal lagoons. They nest in the North American tundras during June and July. In a few weeks the chicks are ready to start the 15,000-km trip to our shores. Between September and October, they arrive at the coastal grasslands where they remain until February, when they start their migration back north to their breeding areas.
