American Golden Plover

Measurements:

Length: 24–28 cm (9+1⁄2–11 in) Weight: 122–194 g (4+5⁄16–6+13⁄16 oz) Wingspan: 65–67 cm (25+1⁄2–26+1⁄2 in) The breeding adult American golden plover has a black face, neck, breast, and belly, with a white crown and nape that extends to the side of the breast. The back is mottled black and white with pale, gold spots. The breeding female is similar, but with less black. When in winter plumage, both sexes have grey-brown upperparts, pale grey-brown underparts, and a whitish eyebrow. The head is small, along with the bill. It is similar to two other golden plovers, European and Pacific. The American golden plover is smaller, slimmer and relatively longer-legged than European golden plover (Pluvialis apricaria) which also has white axillary (armpit) feathers. It is more similar to Pacific golden plover (Pluvialis fulva) with which it shares grey axillary feathers; it was once considered conspecific under the name "lesser golden plover". The Pacific golden plover is slimmer than the American species, has a shorter primary projection, and longer legs, and is usually yellower on the back. In breeding plumage, the American golden plover has a solid black lower belly and undertail, while the Pacific and European golden plovers have at least some to extensive white on the flanks and undertail. …

The breeding habitat of American golden plover is Arctic tundra in northern Canada (Baffin Island west to Yukon and northernmost British Columbia) and Alaska. They nest on the ground in a dry open area. They are migratory and winter in southern South America. They follow an elliptical migration path; northbound birds pass through Central America from January to April and stage in great numbers in places like Illinois before their final push north. In fall, they take a more easterly route, flying mostly over the western Atlantic and Caribbean Sea to the wintering grounds in Patagonia. The bird has one of the longest known migratory routes of over 40,000 km (25,000 mi). Of this, 3,900 km (2,400 mi) is over open ocean where it cannot stop to feed or drink. It does this from body fat stores that it stocks up on prior to the flight. It is a regular though scarce fall migrant in western Europe, with typically 20–25 sightings annually in Great Britain; spring records are much rarer. A comparison of dates and migratory patterns leads to the conclusion that Eskimo curlews and American golden plovers were the most likely shore birds to have attracted the attention of Christopher Columbus to the nearby Americas in early October 1492, after 65 days at sea out of sight of land.

These birds forage for food on tundra, fields, beaches and tidal flats, usually by sight. They eat terrestrial earthworms, terrestrial snails, insects, insect larvae, crustaceans, fish, berries and seeds.
