To mitigate bird collisions, enforce the Migratory Bird Treaty Act

According to a new study published today by the Proceedings of the National Academy of Sciences, communities across residential and urban landscapes need laws and enforcement to reinforce educational efforts and voluntary compliance. In particular, the authors advocate for using the Migratory Bird Treaty Act (1918) to protect birds and reduce building strikes. The study also updates collision mortality estimates to 1.7-2 billion birds per year for North America.
