Petitions and pictures of dead birds will be dropped at Gov. Mark Dayton's front desk this morning.

The Audubon Society is delivering more than 76,000 signatures on a petition asking the governor to get safer glass on the new $1 billion Minnesota Vikings stadium. (The society didn't say where the signatures came from.)

Audubon has been squawking about the potential for birds crashing into the tall glass building while migrating on the nearby Mississippi River corridor.

The society planned a demonstration and call-in campaign to try to compel the governor to insist on bird-safe glass. The Minnesota Sports Facilities Authority (MSFA) previously agreed to work with Audubon on the lighting of the structure at night to help prevent bird-building crashes.

The MSFA and the Vikings have said the fritted glass would cost $1 million and would destroy the airy design and open feel of the building's interior.

The Audubon Society is targeting Dayton because it says he "led the effort to secure $498 million in public money for the construction project" and called it the "people's stadium."

MSFA spokeswoman Jenn Hathaway said the glass already has been ordered.
