Nasty Swan

This one took me by surprise. I was taking some photos of the birds on the lake, when this Swan just started attacking everything around it . It's a bit blurred as the shutter speed was too slow, but I like it all the same as its a moment frozen in time. The extra is of a dog in the lake, ignoring his owners demand to come on, we want to go home. The location is Tredegar County Park near Newport.
