Blue Tit - Nestbox Shuffle

A while ago I intimated that the next stage in choosing a nestbox would be a nestbox shuffle. The bird spreads its wings and shuffles round the bottom of the box.



It seems to be a way of checking whether the box is large enough for a nest and a brood of chicks. If she is satisfied with the box we may see some nest building soon, or maybe it being used as a roost overnight.
