My Eldest made a bird box with her Granddad over the winter holidays a couple of years ago. We put it in the hedgerow when we got home, and promptly forgot about it.
Until a couple of weeks ago, when we noticed a blue tit seemed to be going in and out of it regularly.
The baby blue tits have hatched! We can hear them peeping inside, and this afternoon I got the chance to sit outside and watch patiently from the bench some distance away whilst the parents darted in and out of the box, carrying in food and removing waste.

A wild blue tit appears!

Blue tit with large green grub in its beak perches on the bramble just outside the entrance.
