Caspian Gull, Simon Gillings

The Caspian Gull is a fairly recent addition to the British avifauna, arriving in small numbers in late summer and autumn to spend the winter with us.

The nearest breeding range is around the Black and Caspian Seas; the species has been spreading north and west, which accounts for its presence in some British gull flocks in recent years. It is likely that advances in bird identification have enabled a more accurate recognition of the numbers of this species in Britain.

Adults are very smart white-headed gulls with a long, drawn-out pale bill and long wings.
