Blue Tit

I was trying to repair my sister in law's outside security light when I noticed a lot of flitting and flying going on by my left ear ole. I looked over and realised that Mr & Mrs Blue Tit have made a nest in the wall and there was some serious chick feeding going on. I grabbed my camera and managed to catch this adult bird pausing before taking a caterpillar in to the hungry mouths inside. They are incredibly fast. As well as this shot I have a lot of pictures of a hole in the wall and lots of ends of tails and disappearing birdies. I couldn't fix the security light. It needs a new one.
