MINNEAPOLIS (WCCO) – The Minneapolis city council passed a resolution asking the Minnesota Vikings to change the glass used for their new stadium so it is bird friendly Friday.

Last week, the Audubon Society said the glass used for new Vikings stadium could pose a threat to birds.

According to the Audubon Society, when the glass is very reflective it shows habitat, such as trees and sky, and confuses the birds.

They asked the team and the Minnesota Sports Facilities Authority to modify the stadium’s current specs to be a fritted glass, which is glass is lined with dots that make it visible to birds.

The cost of the new glass would be less than one percent of the overall budget.

The resolution passed in the city council Friday morning.

While this means the city council will join the Audubon Society in asking the Vikings to change the glass, it has no effect on the stadium construction.
