Our friendly bluetit paid Box2 another visit today.
He (and I think it is male) had a good look around.
What's this? It looks as though he is preparing for a visit
from his other half.
And look whose outside.
In she goes!
At least it looks as though she is about to enter the box.
But then at the last minute she gets cold feet and swivels around ...
... and goes out again!
Away she flies! I wonder why that happened.
