For the first time that I can remember, I have the whole family on the roof. This was just half an hour ago. Not much of a photo of the four of them, but does provide some evidence that we can say that the fledge was successful. It takes quite a strong juvenile to fly all the way up to the top of the tower.
And shots from earlier. The first is (I think) Budhin after a rather crash land on the slope of the roof. The second photo shows Gamma (I think) preparing for take off.
