Grey plover or black-bellied plover 
(Choi choi xám, Pluvialis squatarola) 

The grey plover or black-bellied plover (Pluvialis squatarola) is a large plover breeding in Arctic regions.
The bird is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding.

Charadriiformes is based on the Greek word kharadrios meaning "of ravines" or "of river valleys". This Greek word comes from kharadra, meaning "ravine," and it is associated with a yellowish bird from ancient Greek and Roman texts, possibly the ringed plover. 

The genus name is Latin and means relating to rain, from pluvia, "rain". It was believed the birds flocked when rain was imminent.
The species name squatarola is a Latinised version of Sgatarola, a Venetian name for some kind of plover.
