We start again with Harry landing on Box3's entrance hole and going into the box.
As I said on today's front page, we have had more goings on in Box3.
Only a second later, Will comes to the box.
How do I know these are Harry and Will? Well, Harry is a slighter bird with a thinner tail and a thinner neck and shoulders (which are not visible here). Also, he usually goes into the box in one easy movement - he does not hesitate at the entrance hole.
Harry comes up to Will at the entrance ...
... causing Will to drop off his perch.
However, Will appears to be a glutton for punishment and returns to the hole a few seconds later, even though Harry now has a secure position.
This enables Harry to grab Will's claw in his beak again. Harry then tries to pull Will's claw into the nest box!
Will struggles to get away ...
... and probably because he is rather larger than the hole, finally manages to free himself!
Will these two ever sort out their differences?
From what happened earlier, it looks as though Will has a female in tow. Does Harry? Or is he just using the nest box as a roosting place?
