I wonder if they could employ some sort of 3D tracking* and then selectively shutter the relevant mirror whilst the bird flies through, it should only be momentary and not impact performance to a great extent. I'm making an assumption here that there is a way to shutter or otherwise divert the mirror for normal servicing operations, or 'throttling back'
Of course, if the bird gets closer to the boiler, more mirrors will be in play and likely difficult to manage, but this could be combined with an appropriate scare that can be mounted, or flown around the central structure

well, no, that literally is the meaning of fly by wire
It seems that more and more mathematicians are using a new, high level language named "research student".
