What a way to start the day

Woke up early today so off down stairs i went. But as i sat in the living room i could hear a bird chirping loudly. After realising the monitor in the kitchen wasn't on (linked to the bird box) i investigated.

To my delight i had two great tits (i wonder if they are DD and A-cup) flying at the window, chirping at it, pecking at it, flying around and of course posing for me. I wonder if they have found another nesting sight very near here, i need to keep my eyes open and i will let you know, well anyone who is interested anyway, lol. They came back several times and hung around a while and i really enjoyed it. But i think i need to clean my windows, haha.
