When passing this ring barked tree at dawn last Saturday, I noticed a buzzard wedged in the middle forked branch with its back towards me. Buzzards are usually quick to notice things creeping up on them, but this one was definitely slow.
Through my binoculars I saw he had a badly broken beak and was blind in one eye: the latter obviously accounting for my being able to get close to him.
Eventually the buzzard realised I was there and took to the air; the poor bird had only one leg. I guess this was not the luckiest raptor on the marsh.
