Well, today Kelly has made great strides in her nest building. Will she keep it up this time?
This is the state of the nest first thing this morning. Having covered most of the floor on two previous occasions, only to take most of the nesting material out again, we weren't too optimistic when we saw her starting to bring moss into the nest box yet again.
Boris is taking an even greater interest in the nest building process, so much so that he seems to be getting in the way!
Here, Kelly seems to be giving him a nudge - go away, you're being a nuisance
Boris doesn't seem to get the message - here he is again waiting inside the nest box to see what Kelly is up to
Kelly appears to be displaying to Boris. We haven't seen this type of display by a female before and can only guess its purpose by the effect it has on Boris.
As you can see, Boris reacts pretty promptly and leaves the nest box. He doesn't make another appearance all day!
You can understand Kelly's irritation. In spite of his great interest, Boris never brings any nesting material into the nest - but then at least he never seems to take it out either!
I don't know whether that was the response Kelly wanted. She seems fairly surprised and stays in this position for a few seconds after Boris flies out.
