The U-of-M in partnership with the San Diego Zoo is testing a new window film on three of its buildings for effectiveness at reducing bird collisions. Tim Busse (BUS-ee) with University Services says the film has alternating ultraviolet reflecting stripes. He says people inside the building can’t see it at all, and from the outside there’s only a bluish tint that’s barely discernible to humans. “Obviously birds can see it much better,” he says. Officials are apparently moving a different direction at the new Vikings stadium, where the Audubon Society raised concerns about bird collisions. They’re doing preliminary tests of a window film developed by 3-M.
