Grey plover – Pluvialis squatarola
The grey plover, known as the black-bellied plover in North America, is a medium-sized plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. The genus name is Latin and means relating to rain, from pluvia, “rain”. It was believed that golden plovers flocked when rain was imminent. The species name squatarola is a Latinised version of Sgatarola, a Venetian name for some kind of plover.

They are 27–30 cm (11–12 in) long with a wingspan of 71–83 cm (28–33 in) and a weight of 190–280 g (6.7–9.9 oz) (up to 345 g (12.2 oz) in preparation for migration). In spring and summer (late April or May to August), the adults are spotted black and white on the back and wings. The face and neck are black with a white border; they have a black breast and belly and a white rump. The tail is white with black barring. The bill and legs are black. They moult to winter plumage in mid August to early September and retain this until April; this being a fairly plain grey above, with a grey-speckled breast and white belly. The juvenile and first-winter plumages, held by young birds from fledging until about one year old, are similar to the adult winter plumage but with the back feathers blacker with creamy white edging. In all plumages, the inner flanks and axillary feathers at the base of the underwing are black, a feature which readily distinguishes it from the other three Pluvialis species in flight. On the ground, it can also be told from the other Pluvialis species by its larger (24–34 mm (0.94–1.34 in)), heavier bill.
