Here she is about 3½ hours later with another large beak full of moss.
She gives it the normal twist to throw it across the nestbox floor ...
... and again forgets to leave go!
Let's try that again!
Well, at least she remembered to open her beak this time. I can't say the moss was thrown around the box very much though.
Oh no! She's picking it up again!
She went out with the moss and immediately returns to the entrance again.
Here she comes with it a second time.
She can't seem to bring herself to let go of the moss.
This game could go on for a long time!
