What's this - wingless flying?
I could understand this if the bluetit was shooting out of the nest box, but unless it has done a quick 180 degree turn, that is not what has happened here!
You will see that the leaves providing the background to pictures of this box have disappeared. Our next door neighbour has been concerned about the ivy growing up this oak tree and asked the tree surgeon to cut it back while he was here to remove the old birch tree. While there are some advantages to us in having the ivy removed, the external pictures of Box2 now look a little stark!
