American Golden-Plover

The American Golden-Plover is a medium-sized shorebird renowned for one of the longest migrations of any bird in the Americas, breeding on Arctic tundra and wintering primarily on the grasslands of southern South America. In breeding plumage it is a striking bird, with densely spangled gold-and-black upperparts and solid black underparts bordered by a bold white stripe running from the forehead down the sides of the neck and flanks.

Outside the breeding season, its plumage becomes far more subdued, showing brownish-gray mottled upperparts and pale, lightly marked underparts, requiring more careful attention to structure and subtle pattern for identification. It closely resembles the Pacific Golden-Plover and Black-bellied Plover, both of which share the general "golden plover" body plan of spangled upperparts.

A densely spangled gold-and-black feather, or in non-breeding plumage a plain grayish-brown mottled feather, found in open grassland, farmland, or mudflat habitat along its long migratory route is a good indicator of this species.

Shape and Size

Body feathers are moderate in size for a medium shorebird, with flight feathers built for sustained long-distance migratory flight, notably long and pointed relative to many other plovers.

Color and Pattern

• Breeding upperpart feathers show dense gold-and-black spangling, each feather marked with golden-yellow notches along a blackish center.
• Breeding underparts are largely solid black, bordered by a bold white stripe running from the forehead down the neck sides to the flanks, but the black typically continues to the undertail area.
• Non-breeding feathers are plainer, showing grayish-brown upperparts with buffy mottling and pale, lightly streaked underparts.
• Flight feathers are dark brownish-gray with little contrasting wing stripe.

Shaft and Vane

Shafts are dark on most upperpart feathers, with the golden spangling formed by notching along the feather edges rather than the shaft itself.

Distinguishing from Similar Species

Compared to Pacific Golden-Plover, American Golden-Plover in breeding plumage retains black coloration extending further toward the undertail area rather than showing white flanks below the black, and it has proportionally shorter legs. Compared to Black-bellied Plover, American Golden-Plover shows golden rather than white-and-black spangling on the upperparts and lacks the black axillary ("wingpit") feathers visible in Black-bellied Plover's flight feathers.

Breeding adults show densely spangled gold-and-black upperparts and solid black underparts bordered by a bold white stripe from the forehead to the flanks. Non-breeding adults and juveniles are considerably plainer, with grayish-brown mottled upperparts and pale, faintly streaked underparts. Sexes look similar, though females may average slightly less extensively black below. The species undergoes a complete molt after breeding into non-breeding plumage, followed by a return to bold breeding plumage via a pre-breeding molt in late winter to spring.

The American Golden-Plover breeds on Arctic tundra across northern Canada and Alaska, and undertakes a remarkable long-distance migration, with much of the population making an extended nonstop flight over the Atlantic Ocean to reach wintering grounds on the grasslands and pampas of southern South America. During migration it also uses inland grassland, farmland, and mudflat habitat in North America.

This species forages using a run-stop-peck technique on open ground, taking insects and other invertebrates from grassland, farmland, and mudflats. It is often found in flocks during migration, sometimes associating with other shorebirds. Its call is a clear, whistled note, useful for confirming identification. Nests are shallow scrapes on open Arctic tundra. For feather finders, a densely gold-and-black spangled feather encountered during migration in grassland or farmland, or a plainer grayish-brown mottled feather in non-breeding season, is a good indicator of this species, especially when Black-bellied Plover's diagnostic black axillary feathers are absent.
