last week I could hear yellowhammers practising their song. They could manage the "bit of bread" and "cheese" but not the whole phrase. Today there were several sitting in the tops of trees giving it full blast and using the whole phrase.
There was also an odd episode in the field behind our house. A buzzard flew down from a tree in our garden into the field. It was immediately the subject of a spectacular aerial attack by another buzzard. They appeared to be fighting for a minute or so before one flew off, and then the other flew off, neither seemed injured. I have never seen this behaviour before (they are quite furtive birds as a rule other than when they are in the air or roosting on a pole)
