> add a light or buzzer I doubt these machines are silent already.

  The article mentions this. They're loud and have bright lights. The problem is these disorient the birds, and they struggle to escape in time. Not really surprising, if someone woke me up at 3am with an industrial hoover and a foglight I would probably panic too.

    They are loud, approach slow, have bright lights, there are loud people talking and working around... and the birds keep sleeping and do not try to escape or avoid the area? Seems unlikely I can't eval the problem with this data and never had heard of it before. Nor had seen any remains of birds in almazaras but my experience in this case is limited. Maybe is a true problem locally and is good to care for it... something does not fit in this narrative. Maybe the migrating birds are just too tired to escape?. I would look for some hidden interests. The history is very strange. In any case just put a red light in the extreme of the vacuum tube, and you'll have a cheap and pretty simple solution. Birds will avoid the tube if they can see it coming closer.
