Multiple sources report that collisions with building glass are a significant threat to birds in Canada and across North America. One outlet notes that tens of millions of birds die each year in Canada after crashing into glass on buildings. Another source links the broader problem to large-scale bird population declines, stating that nearly 3 billion birds have been lost across North America since 1970 due to human activities affecting birds and their habitats, which includes risks from glass-walled structures.
Both articles argue that bird-safe glass should become a standard building practice to reduce these collisions. They frame building design and materials as a controllable factor that can mitigate harm by making glass more visible or otherwise less hazardous to birds. The reporting emphasizes that bird deaths from glass collisions occur at a large scale and calls for wider adoption of solutions that prevent birds from mistaking reflective or transparent surfaces for open flight paths.
Overall, the sources agree on the scale of the problem and the need to shift from current norms to bird-safe materials as a practical intervention.
