When I say 'Push' - PUSH!!

I hung this nesting box up last year and was not really expecting it to be used for a couple of years.
It was windy last night and it was hanging a bit squint.
I was just about to go out to straighten it when I noticed a wee face at the door.
I hope that the Blue Tits have success in their new home this year.
