Who you looking at

It's my earliest blip yet, but I couldnt resist this one. I was out side watching some great tits starting to take nest building materials into my bird house (I'm very excited about this). when after watching them fly back and fore for a while I noticed one deviate to a mirror on the floor next door. I lifted my camera because I knew what was going to happen as I had a glimpse of this yesterday through the bathroom window. He attacked this mirror with vigour, unfortunately the light was not that good so the pic is of fairly poor quality. I think I need to be better prepared tomorrow as I may start a series of "Tits in a Box", following my new residents.
