Adults are 33–36 cm long. They have long pink legs, a long thin black bill and are blackish above and white below, with a white head and neck with a varying amount of black. Males have a black back, often with greenish gloss. Females' backs have a brown hue, contrasting with the black remiges. In the populations that have the top of the head normally white at least in winter, females tend to have less black on head and neck all year round, while males often have much black, particularly in summer. This difference is not clear-cut, however, and males usually get all-white heads in winter.
Immature birds are grey instead of black and have a markedly sandy hue on the wings, with light feather fringes appearing as a whitish line in flight.

Herring gulls are large, noisy gulls found throughout the year around our coasts and inland around rubbish tips, fields, large reservoirs and lakes, especially during winter. Adults have light grey backs, white under parts, and black wing tips with white 'mirrors'. Their legs are pink, with webbed feet and they have heavy, slightly hooked bills marked with a red spot. Young birds are mottled brown. They have suffered moderate declines over the past 25 years and over half of their UK breeding population is confined to fewer than ten sites.
