The Grey plover (Pluvialis squatarola) also named Black-bellied Plover, is found only along the coast, preferring sandy and muddy estuaries. It has a spotted, white and silvery-grey back and pale grey and white underparts. In the spring, when adults migrate north through Britain, they have black throat, chest and belly. The Grey Plover is the only American plover that has a hind toe on its foot. The hind toe, however, is so small that it is difficult to see in the field. They can be found on six different continents during the winter season, but breed only on the Arctic tundra.
