Anyone trying to watch the live stream from the Great Tit nestbox earlier today would have found a missing connection. Not my fault this time. I had noticed a couple of pop up messages from the PC saying it was re-connecting to the router. What I hadn't realized was it had changed its IP address thus breaking the link. It took a while to sort that out but I think I have found a permanent solution so all should be active again now.
At least one youngster is very active with the wing flapping exercises and seems to be wanting to reach the exit hole so it won't be too long before they begin to fledge.
