More Beddington Gulls

Pic 1: Caspian Gull in flight (click on it)- even from this range, the white head, dark shawl, broad pale fringed-discretely dark centred mantle/scaps, dark based/pale tipped coverts and secondaries and contrasting rump with black tail band can be visible in flight. The long winged, long-billed and long necked posture makes it distinctive in flight and readily identifiable in a melee of flying gulls.

A 'Caspo'- didn't see much on it.
