Since taking this shot of Mummy or Daddy Blue Tit, I have discovered another nest in the box on the silver birch tree in the back garden. I was hanging washing out and I could hear little baby birds squeaking so I stood and listened and then saw both blue tit parents flying to the box to feed their young so we are going to have 2 broods of tits. The nest box was on the back garage but nobody went in there last year so Steve moved it onto the tree. It was a nest box which my Dad had made and we took it down when we sold Mum's bungalow after she died so I'm glad it's giving the birds a good home.
