Blue tit chicks fledged last night - some at 1am.

I'll post a fledging video of this on Sunday.

Four chicks fledged just after 1am, which I understand is most unusual.
The three remaining chicks fledged at around 6am with their parents helping.

I've looked at the nest box footage and it looks like one of them was in a panic and scaring the others. No preditor got into the box, but it was almost that one had and there was panic that I haven't seen before.

With a bit of luck they're all ok.
