Hudsonian Godwits are large shorebirds with long, slightly upturned bills that are pink or orange near the base. In flight or when preening, they show a black tail, a white rump, and dark underwing coverts, features not shared by the slightly larger and longer-billed Marbled Godwit.
In late spring and early summer, Hudsonian Godwits breed in parts of Canada and Alaska, timing their efforts with the abundance of invertebrate species available during the green season. By late summer, adults head south (followed later by juvenile birds), with some touching down at select sites in New England, like flooded fields, coastal beaches, marshes, and mud flats, before continuing on to southern South America (many more are thought to fly non-stop for several days from Canada over the Atlantic Ocean to South America). Having experienced part of summer in the far north, those that successfully complete their incredible journey get to experience summer in the southern hemisphere as well.
