Stacey - I don't mind at all! Yes, we hope to continue next year, and my husband is already planning for it. We hope that it might be possible to have some video clips as well. Last year you could look at a frequently refreshing webcam image, choosing which one of the two boxes you looked at. For a while we (this is the Royal "we" - Malcolm does all the photographic stuff) had a camcorder on a tripod in the dining room, and this was focussed either on the bird table, or on the mealworm feeder on the window, so you had a third choice.
The parents continue for quite a few days to feed the chicks - we could see them in the shrubs at the bottom of the garden, waiting for mealworms to be delivered from the feeder we had down there. Towards the end of this year's story, you will find a photo called "Fluffy and her chicks" - this feeder is right outside the kitchen window, and we continued to see them feeding together there for some time.
Yes they all leave the nest for good, though occasionally for a short while an adult might return for a quick look round. We presume the birds roost in the trees and hedges - itt seems such a waste of a nice cosy box! One of our friends (whose company supplies the image-detecting software) already has a bluetit roosting in his box, and I know several other people find this, but not so far, for us.
On our links page, you will see quite a few other sites with camera equipped nestboxes, and you might find Vickie's interesting - she lists places all over the world where there are webcams, quite a few in the US.
