Here is Bella in Box2 again. At the start of a new day, the box is empty and she has just brought in a nice piece of hay.
This is the silly season for nesting bluetits. Both Box1 and Box2 have been taken over by a pair of bluetits, and in both boxes the female is still only playing at nest building. Box3 is still more open. There have been bluetits and great tits regularly visiting it, but no birds have yet claimed ownership of the box.
