Common gull
The common gull ("Larus canus") is a medium-sized gull that breeds in northern Asia, northern Europe, and northwestern North America. The North American subspecies is commonly referred to as the mew gull, although that name is also used by some authorities for the whole species. It migrates further south in winter. There are differing accounts as to how the species acquired its vernacular name (see Etymology section below).
