The Fatal Light Awareness Program (FLAP) convinced 80 buildings in downtown Toronto, Ontario to turn off their lights at night during bird migration seasons. Night traveling birds on migration routes are attracted to illuminated buildings especially on overcast nights. The World Wildlife Fund joined the effort creating the Bird Friendly Building Program to help spread the message to U.S. cities. Between 100 million and 1 billion birds are killed in North America each year from window collisions.
