Urban light creates a fatal attraction and disorients migrating birds, which often fly around until exhausted and drop to the ground. Or they may strike a building or window. To prevent these needless deaths, the city of Toronto has created a “Lights Out Toronto” program. Lights go out in city-owned buildings after work and on weekends. And their Bird-Friendly Development Guidelines offer common-sense lighting practices for managing a tall building or a ground-level home.
