I took a trip (with the help of my free bus pass!) to Highfields Park – next to Nottingham University Park – this afternoon. My birdwatching neighbour had sent me a photo of nuthatch at what looked like a nest-hole in one of the ash trees. I was pleased to be able to find it quite easily. It looks as if he (or she) is adapting a woodpecker hole with the aid of beaks full of mud. You can see some of the construction inside the hole.
