This is Box1 (Georgie and Wills) and here it looks as though Wills has brought some tit-bit in for Georgie, only to find her not in the nest box.
Anyway, it gives us an opportunity to count Georgie's eggs. I think I can make out 7 of them - but perhaps I am influenced by the fact that this is the number that ought to be there if you assume that one egg is now being laid each day.
