MINNEAPOLIS (AP) — The University of Minnesota is experimenting with a reflective film on campus windows to see if it can avert bird collisions.

A research team from the San Diego Zoo this summer installed video cameras and "shock sensors" at three buildings at the university.

The university is a magnet for birds because of its closeness to the Mississippi River flyway.

Veterinary technician Stephanie Beard has been tracking birds' collisions with windows on campus. Beard helped point the researchers to what she calls "the most deadly areas on campus for bird collisions."

Paquita Hoeck is heading the research for the San Diego Zoo. Hoeck says the hope is that the birds might have better luck spotting the glass if it's covered with stripes of ultraviolet-reflecting film.
