Grey Plover
Pluvialis squatarola
The Grey Plover, also known as the Black-bellied Plover in the New World, is a robust shorebird recognized for its extensive migratory journeys. This species exhibits a striking transformation in plumage between its breeding and non-breeding seasons. It is a widespread bird, found on nearly every coast outside of Antarctica.

01 / The telltale details
You’ll know it
when you see it.
Start with shape and behavior. Then look for the smaller details.
- 01
Breeding Adult
Adults in breeding plumage have spotted silver-white and dark grey upperparts with black underparts. A prominent white band extends from the forehead down to the breast sides.
- 02
Non-breeding Adult
Outside the breeding season, adults are speckled brownish-grey above with golden-brown and whitish streaks, lacking the black underparts. Their face is pale grey with a white streak above the eye.
- 03
Juvenile
Juveniles resemble non-breeding adults but have darker grey-brown upperparts with bold pale-gold or yellowish-white spots, giving a spangled appearance.
- 04
In Flight
In all plumages, a diagnostic black patch in the inner flanks and axillary feathers at the base of the underwing distinguishes it from other plovers.
02 / A place in the world
Where life
takes it.
Grey Plovers breed in Arctic regions, favoring open, dry tundra with good visibility. Outside the breeding season, they are almost entirely coastal, found on marine shores, estuaries, lagoons, and mudflats. They may occasionally be found inland during migration.
Stay a while. Or follow the season.
Grey Plovers are long-distance migrants, breeding in the Northern Hemisphere and moving south for the boreal winter. They typically arrive at wintering grounds from July, peaking in autumn, and depart from April onwards.
03 / Listen a little closer
A voice
of its own.
Their usual call is a loud, far-carrying, melancholy whistle composed of three notes, with the middle note lower-pitched.
04 / The life behind the feathers
A day in its world.
On the menu.
Their diet primarily consists of marine invertebrates such as polychaete worms, molluscs, and crustaceans. On breeding grounds, they also consume insects and other terrestrial invertebrates.
Grey Plovers forage by sight on beaches and tidal flats, employing a characteristic stop-start running, pecking, and probing method. They typically feed individually or in small, loosely associated groups.
A place to begin.
Breeding occurs from May to mid-June. The female constructs a shallow scrape on the ground in dry, open tundra, lining it with pebbles, moss, and lichens. They typically lay four eggs, which both parents incubate for 26-27 days.
The little routines.
Grey Plovers are generally less social than some other plover species, often feeding alone. They form mixed roosting groups at night. They are sensitive to disturbance and tend to stay far out on mudflats.
One more reason to pay attention
A familiar face.
A few surprises.
The Grey Plover is known as the Black-bellied Plover in the New World.
The genus name *Pluvialis* is Latin for 'relating to rain,' as it was once believed these birds flocked when rain was imminent.
Grey Plovers have been observed deliberately feeding on barrel jellyfish on the Black Sea coast, suggesting coelenterates may be a more important food source than previously thought.
