Bird-window collisions are one of the leading causes of mortality for birds. Each year, an estimated 42 million birds die in Canada due to window collisions. Upon hitting a window birds often die or are stunned, leaving them vulnerable to predation by scavengers such as crows, gulls, rats, cats and racoons.

Current estimates of bird mortality from window collisions are based on work conducted in eastern North America. This presents an urgent need to understand window collision impacts in western Canada. In an effort to address this gap in information, Bird Studies Canada has launched a Volunteer Citizen Science monitoring project that aims to assess mortality rates, identify vulnerable species, and identify areas of Vancouver that pose a risk to birds.
