We were late switching on this morning, and when we did, there was a bluetit inside Box2.
It was only a brief visit though.
This time it's Box2 that gets a visitor.
Two and a half hours later, we get another visitor. Here a bluetit is coming into land on the nest box hole.
With little hesitation, it enters the nest box.
Here it is inside Box2.
After a while, it pops back up to the hole to look outside.
Soon, it sees a spot to fly to ...
... and pops up there to think.
