Shortly after 2pm today I had to shut down i-Catcher for a short period of maintenance.
This was the state of Box2 at 2:14pm.
Today the first time this season that moss was brought into one of our nest boxes!
Obviously, that was the time that a bluetit chose to bring nesting material into the box for the first time this year!
When I started i-Catcher again at 3:02pm, this is what greeted me. Nesting material has been brought into Box2!
