Caspian gull

Sorry have only two usable long distance shots of the gull, this is the second.  It was not possible to get close to the gull and dog walkers, children throwing stones into the river and a family having a BBQ nearby didn't help. However, when I first saw the gull I could see that it was different from the other gulls around it. I knew it wasn't a Herring gull and I was sure it wasn't a juvenile Great Black-backed gull so I did some research on Google and the closes match that I could find was the Caspian gull. It swam off towards Instow so I don't have any flight shots.

Eds: Thanks for that.. As suspected it is a 1st summer Herring Gull. Caspian Gull (a rare bird in Devon requiring a full blown description of all aspects of its plumage) would have a longer looking bill, longer primaries, almost unmarked undertail coverts, tertials usually only pale tipped (not edged like this bird) and greater coverts on wings would be darker centred and not so chequered.
