I was watching this tiny coal tit whilst it was taking seeds from my feeders when I turned round and turned back, I think it knocked itself out on my shed? It was on the floor and squeaking, so I ran down the garden and picked him up, just as it started to rain. Then I held him for 5 mins and kept him from the cats in the garden. And he flew away after that. Sooooo tiny. I feel honoured. He wasn't damaged, as far as I can see, and now he's back pecking at the feeders. Yay!
