Spring is the season when migratory birds head back to Michigan from their warm winter vacations down south. Their already arduous journey hits new obstacles when buildings impede their airway, especially when so many species migrate at night. The State of Michigan has followed suit with other regions in the country by implementing Safe Passage Great Lakes Days. From March 15-May 31 and August 15-October 31 landowners with buildings five stories or higher are encouraged to turn off their lights or close blinds or curtains from 11pm-6am, to avoid disorienting migrating flocks. The tactic also helps conserve energy as well as protecting the many species of birds that help make Michigan's wildlife so vibrant.
