Birds are facing a crisis — nearly three billion birds have been lost across North America since 1970 as a result of human activities impacting birds and their habitats.

Each year, billions of birds migrate across vast ranges spanning the Americas. For many, the journey is fatal. In Canada, tens of millions of birds are killed annually by crashing into glass on buildings, most of which are low-rise or residential. This makes collisions with glass a leading direct cause of bird fatalities.
