Formerly restricted to the Black Sea and the eastern Mediterranean this species has now expanded over most of Europe as far as the Great Britain and Ireland, with 37 sites: 543–592 pairs in the United Kingdom in 2008. In Ireland breeding has been recorded in at least four counties. Breeding has also occurred in Belgium, the Netherlands, Denmark, Sweden, Estonia, Switzerland, the Czech Republic,Hungary and the Balkans.
In winter, this bird migrates to Mediterranean and Atlantic coasts.
This gull breeds in colonies in large reedbeds or marshes, or on islands in lakes; where its population is small, it nests in black-headed gull colonies. Like most gulls, it is highly gregarious in winter, both when feeding or in evening roosts. It is not a pelagic species, and is rarely seen at sea far from coasts.
The Mediterranean gull's feeding habits are much an opportunistic omnivore, eating fish, worms, scraps, insects, offal and carrion.
This is a noisy species, especially at colonies, with a nasal "yeah" call.
The Mediterranean gull is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. from Wikipedia, the free encyclopedia
