Lesser Black-Backed Gull.

The lesser black-backed gull was described by Linnaeus in his 18th-century work, Systema Naturae and it still bears its original name of Larus fuscus. The scientific name is from Latin. Larus appears to have referred to a gull or other large seabird and fuscus meant black or brown.
A confusable species is the great black-backed gull. The lesser is a much smaller bird with slimmer build, yellow rather than pinkish legs and smaller white "mirrors" at the wing tips. The adults have black or dark grey wings and back. The bill is yellow with a red spot which the young peck at, inducing feeding.
