The grey plover or black-bellied plover (Pluvialis squatarola) is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. The grey plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tringa squatarola. It is now placed with three other plovers in the genus Pluvialis that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name is Latin and means relating to rain, from pluvia, "rain". It was believed that they flocked when rain was imminent. The species name squatarola is a Latinised version of Sgatarola, a Venetian name for some kind of plover.
The English common name used for this species differs in different parts of the world. It is generally known as "grey plover" in the Old World and "black-bellied plover" in the New World. Three subspecies are recognised: Wikipedia →

Likely
About 60% of wildlife watchers report a Black-bellied Plover sighting in Padre Island National Seashore on a given day, based on 1,086 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 171 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 80% of wildlife watchers report a Black-bellied Plover in Padre Island National Seashore on a given day, against about 50% in January–March and June, the lowest months. That is one of Padre Island National Seashore's wettest months, with about 120 mm of rain against 40 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black-bellied Plover sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 64 parks where we can rate Black-bellied Plover sightings, Padre Island National Seashore has the highest daily chance: about 60%. Next come West Coast National Park (South Africa, about 60%) and Ría Lagartos Biosphere Reserve (Mexico, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black-bellied Plover is recorded against all the birds logged in Padre Island National Seashore (1,086 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
