You can see the adult Mew Gull with yellow feet and the juvenile with gray feet in this photo. I watched the juvenile stamping in the shallow water at low tide, probably stirring up the worms for food.
The Common Gull (European and Asian subspecies; see below) or Mew Gull (North American subspecies) Larus canus is a medium-sized gull which breeds in northern Asia, northern Europe and northwestern North America. It migrates further south in winter. Its name does not indicate that it is an abundant species, but that during the winter it feeds on common land, short pasture used for grazing.
