The Hudsonian Godwit breeds in lowland marshes in the tundra of North America from Alaska to the Hudson Bay. Almost the whole population, reckoned to be about 50,000 individuals, gathers at Hudson Bay and James Bay in Canada before flying south over the west Atlantic towards Argentina and Chile. Jaramillo states that "over 50% of the world's population winters in large bays of Tierra del Fuego, with 25% wintering in inlets of Chiloe island."
