Demand that U.S. Bank Stadium be Retrofitted to Prevent Migratory Bird Strikes

In 2016 the Minnesota Sports Facilities Authority opened a new facility to house the Minnesota Vikings(among others). Prior to the construction, the  Minnesota Department of Natural Resources warned that the design of the building could lead to a high number of bird strikes and subsequent deaths due to the structure's design. The architecture is largely glass and highly reflective, thus mirroring the sky, trees, etc. This is highly confusing to birds and results in the birds colliding with the structure, often breaking their neck and killing them. The Minnesota Sports Facilities Authority (MSFA) has funded a study of the impacts of the building on migratory bird strikes and the early results as reported by the Audubon Chapter of Minneapolis are as follows: 

During the period of observation, 74 birds of 21 species were recorded. Of these birds, 60 were killed and 14 were observed either stunned on the ground or stunned after colliding with the glass windows. The survival rate of the stunned birds is unknown.

For comparison, the highest mortality recorded for a single building in Minneapolis during a three-year study of bird-building collisions was 250 birds over six migration periods,7 averaging 42 birds per migration period.

If the fall 2016 migration season’s total of 60 documented avian deaths were to remain consistent in the future during spring and fall migrations, approximately 360 birds would be killed by U.S. Bank Stadium in a three-year period. And this number significantly underestimates true mortality at the stadium complex, because it does not include birds removed by maintenance staff, security guards, and scavengers. These and other factors contributing to the underestimate of actual mortality are described in the section “Evidence of Underreporting of Bird Deaths.”

Please sign this petition if you demand that the Minnesota Sports Facilities Authority (MSFA) take immediate action and follow best practices for preventing bird strike as described by American Bird Conservancy and the US Fish and Wildlife Service. Similar methods employed at New York's Javits Center reduced bird strikes by 90%! The Minnesota Vikings, their ownership, U.S. Bank, and the State of Minnesota must take immediate action to prevent further damage to the migratory bird population.
