Pluvialis squatarola
Grey Plover (Pluvialis squatarola)
Featured photoblack-bellied-plover.jpgPluvialis squatarola, the grey plover (called 'black-bellied plover' in North America), is a medium-sized plover of the family Charadriidae, with a near-cosmopolitan non-breeding distribution. Adults are 27 to 31 cm long with a wingspan of 71 to 83 cm and weigh 170 to 320 g. Breeding plumage shows a striking jet-black face, throat, and belly contrasted with pure white forehead, neck-band, and rump; non-breeding plumage is uniformly mottled grey. The IUCN lists the species as Least Concern.
Quick facts
- Habitat
- Coastal mudflats, sandflats, estuaries, and beaches across the world's temperate and tropical coasts during the non-breeding season; high Arctic tundra during breeding.
- Range
- Breeds on high Arctic tundra of North America, Greenland, and Russian Arctic. Winters on coasts across the Americas, Europe, Africa, Asia, and Australia — one of the broadest non-breeding distributions of any plover.
- Size
- 27–31 cm body · 71–83 cm wingspan · 170–320 g
- Plumage
- Breeding adults show a striking pied pattern — jet-black face, throat, breast, and belly contrasted with pure white forehead, supercilium, neck-band, undertail, and rump; the back is heavily speckled black-and-white. Non-breeding adults are uniformly mottled pale grey above with paler grey-white underparts and no black belly. The black 'wing-pit' (axillary feathers) visible in flight is diagnostic in any plumage.
- Song
- A clear, mournful, three-note whistled 'plee-uu-wee' delivered both in flight and from the ground — among the most distinctive shorebird calls in any region. The breeding-territory display call is rarely heard outside the high Arctic.
- Migration
- Long-distance migrant. Arctic breeders travel south to coasts across nearly every continent. Annual round-trip migrations of 10,000-20,000 km are typical.
- Conservation
- Least Concern (LC)
Overview
Pluvialis squatarola is one of four Pluvialis plovers worldwide (with the closely related American golden plover P. dominica, Pacific golden plover P. fulva, and European golden plover P. apricaria). The species is the largest Pluvialis and the only one that occupies coastal mudflats year-round across most of its non-breeding range.
Distribution
The breeding range covers high Arctic coastal tundra in North America, Greenland, and across Russian Arctic. Wintering grounds extend across the Americas, Europe, Africa, Asia, and Australia — virtually every temperate and tropical coastline outside the polar zones supports grey plover populations during the non-breeding season. The species is one of the most cosmopolitan plovers worldwide.
Diagnostic black axillaries
The grey plover's axillary feathers (the 'wing pits' visible only when the wings are fully spread in flight) are jet-black in all plumages. The dark wing-pit is the most reliable field mark for identifying the species in any season — the otherwise grey-and-white non-breeding plumage can be confused with several other shorebirds at a distance, but the black axillaries are unique. The trait distinguishes grey plover from the very similar American and Pacific golden plovers.

Frequently asked questions
Why is it called 'grey plover' in Europe but 'black-bellied plover' in North America?
The two English names emphasize different plumages. 'Grey plover' (the standard British and IOC English name) describes the species' uniform pale grey non-breeding plumage that is most familiar on European coasts during winter passage and wintering. 'Black-bellied plover' (the standard American name) describes the striking black-bellied breeding plumage that birders see during spring and summer migration through the United States. Both names describe the same species in different seasonal plumages.
How can you tell grey plover from golden plover?
The most reliable field mark is the axillary feathers (the 'wing pits' visible only in flight). Grey plover shows jet-black axillaries; the closely similar American golden plover and Pacific golden plover both show white-grey axillaries. Several other plumage and bill differences also separate the species, but the axillary contrast in flight is unambiguous.
How widely distributed is the grey plover?
Grey plover has one of the broadest non-breeding distributions of any plover worldwide. Arctic breeders travel south to coasts across the Americas (from Alaska to Tierra del Fuego), Europe, Africa, Asia, and Australia — virtually every temperate and tropical coastline outside the polar zones supports the species during the non-breeding season.
