The European herring gull (Larus argentatus) is a large gull, up to 66 cm (26 in) long. It breeds throughout the northern and western coasts of Europe. Some European herring gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, such as in Ireland, Britain, Iceland, or on the North Sea shores. They have a varied diet, including fish, crustaceans, as well as some plants, and are also scavengers, consuming carrion and food left by or stolen from humans.Herring gulls breed in much of north-western Europe, including Iceland, the United Kingdom, Ireland and France. Since 2009, herring gulls in the United Kingdom have been on the red list of birds of conservation concern.
They have been recorded from all the coasts of Europe including the Mediterranean and occasionally inland. Vagrants have been recorded in Israel, Cyprus and Turkey.
Birds in France are mainly resident, but northern populations migrate in winter, generally to the coasts of north-western Europe.
