A few years ago this male Sparrowhawk would bathe in our garden pond, almost daily. On this occasion I was in my hide photographing smaller birds when it turned up. The lens I was using was far to big to fit all of the bird in and get shots of it bathing. So I literally crawled out of my hide and managed to get to the house, collected my 300mm lens , crawled back, swopped the lenses and the job was done. Who says you can't outwit a bird of prey.
