Where Are All Of Minneapolis’s Dead Birds?

By my count, the 35 tallest buildings in Minneapolis have about 1,200 stories, and all of them have a lot of windows, if not solid glass walls.   That’s a lot of glass.

Vikings_stadiumThe new Minnesota Vikings Stadium will be 30-stories at its highest point, and it has glass walls on part of it.   Therefore, bird advocates warn Minnesotans that the new stadium is going to be responsible for the death of about 1,000 birds per year, even with the lights turned off at night. So, they are demanding that the Vikings owners pay for polka dot windows, which apparently mitigates the birdocide, but is less beautiful to the Wilfs.

If that’s true, why don’t Minneapolitans currently see tens of thousands of dead birds lying around their glassy city?  That many bird corpses would be difficult to miss.  I’m very open to the possibility that this is simplistic thinking, but can someone explain where all the dead birds are?
