Hole in one, or a Birdie?

Inspired by Wendles' post yesterday to try again at photographing the blue-tits in our garden.

I stood there very still for about 10 minutes as they fluttered about the box before retreating behind an upturned table a bit further away (the camera could only just reach). Anyway after 10 minutes I had many misses and a few OK shots, mostly when the birds missed the covered hole...
It was an interesting experience and form the noises coming from inside i suspect they have 2-5 chicks in there =)

I wasn't happy with the colours around the bird so removed them.
