At first glance you might think this is just another black-headed gull, which are quite common at Lindisfarne. However, this is the much less common Mediterranean Gull. The most obvious difference is the size of the black on its head. Black-headed gulls are mainly black over the face and part of the neck, whereas Mediterranean Gulls have black much further down their neck. The black tends to be a deep pure black rather than dark brown on the black-headed gulls. White wing tips and yellow tip to the bill are also characteristic.
