The American golden plover (Pluvialis dominica) is a medium-sized plover.

Note dusky back and axillaries.

Description

Adults are spotted gold and black on the crown, back and wings. Their face and neck are black with a white border; they have a black breast and a dark rump. The legs are black.

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 was once considered conspecific under the name "lesser golden plover".[2] 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.

Feeding and Breeding

These birds forage for food on tundra, fields, beaches and tidal flats, usually by sight. They eat insects and crustaceans, also berries.

The breeding habitat of American golden plover is Arctic tundra from northern Canada 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 about January–April[3][4] 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 vagrant to western Europe.

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 nearby America in early October 1492, after 65 days at sea out of sight of land.[5]

Status

Large numbers were shot in the late 19th century and the population has never fully recovered.
