I see that the male raven just escorted the female back to the nestbox, then he left, but not before what looked like a very vocal argument with one, or both, falcons. I think for him to survive being attacked while flying to another building, he is going to have to be very clever, especially as he almost got killed yesterday. I can't see the female raven laying any more eggs with all this conflict going on around her. I don't think there is any chance of them keeping the nest box, but I sure hope they can both escape being killed.
