As for the university – they probably died of boredom listening to intro course lectures.

And poop a lot. For decades, they invaded the Rice University campus each year, including the main quadrangle and the trees outside most of the classroom buildings, and over a period of 2-3 weeks they coated the area with BS. It got so bad that all students and faculty attending early evening classes or events carried umbrellas. When the grackles were done doing that, most of them (every year) caught some plague and died, leaving the same area covered with bird carcasses, which rotted in the rain until campus groundskeepers managed to clean them up. Various clever tricks were tried to persuade them to choose somewhere else for their gatherings, including broadcasting the sounds of predators from loudspeakers in the trees… all to no avail.

I’m on Tonto’s side in this conflict.
