That swan is one angry fellow. He went berserk at me last year! I was running for my life!
I saw a family - mum, dad and three or four children, 'trapped' by him yesterday. I showed them how to walk past (the swan wasn't being worryingly aggressive, he was just being a swan) but they wouldn't follow me!
Also had all the ususal stuff but with the addition of a Merlin flying over the car park at mid day, last seen flying north-east over the A361.
