The Gann, continued..

Following on from Dave`s post,  we were some  hundred metres apart this afternoon scanning the gull flock, however we both managed to read a couple of Med Gull rings - Yellow AZUS & White 3557.. The female Eider was close inshore  allowing for some good pics. On the way back  to the car park a Buzzard landed n the beach heckled by a couple of Crows. could this have been the  unseen culprit that caused the Gulls to take flight a couple of times?
