Here she is approaching the nest box with her first beakful.
The female in Box3 has started bringing in nesting material.
In she goes!
Well, she's inside the box, but she seems to have lost hold on the moss on the way in!
A quick yank ...
... and if that doesn't do the trick, then strong arm tactics have to be employed!
Got it in at last!
A nesting wriggle to celebrate!
And another!
About to go?
Not quite!
"What's that up there?"
Obviously, nothing as important as another nesting wriggle!
She must be going this time.
She's on her way.
Well, a start has been made!
