This is Box2 again, and this looks like a nesting wriggle to me!
First observed nesting wriggle in Box2!
Not much doubt about it really.
Why else would a bluetit get herself into this position!
Wriggle completed.
This is the start of another common sequence. The male bluetit as gone into the nest box ...
... and is expecting his partner to follow him inside. You can see the expectation in his posture.
Suddenly she arrives! The female is the rather worn bluetit with the broken bit of feather.
In no time at all, the male departs leaving the female on her own in the nest box.
She doesn't stay long. After all, there is not much to do by herself and she has seen it all many times before.
This year we have seen more coal tits in the garden than ever before. However, we have never had one in a nest box. Will this be the first time?
Well, it has landed on the nest box entrance hole.
Is it going to go inside?
No luck. Suddenly it took fright and flew off.
It must have immediately turned around and come back to the box because 8 seconds later it is back.
Was this the reason for the coal tit's departure? Thirty seconds after a bluetit appeared looking very proprietorial.
Having settled on the roof of the nest box, it had to do a somersault to get inside.
That looks more under control again.
In it goes.
