(Edmonton) The thud of a bird hitting a window is something many Canadian home owners experience. Up until now, little research has been done to document the significant these collisions for Canada's bird populations. A University of Alberta biology class project supervised by researcher Erin Bayne suggests that many birds meet their end in run-ins with Canadian homes.
The U of A students estimate a staggering 22 million birds a year die from colliding with windows of homes across the country. The research was done in Edmonton and surrounding area using evidence gathered from more than 1,700 homeowners. Homeowners were recruited to become citizen scientists for the study. The citizen scientists were required to complete an online survey where they were asked to recall fatal bird hits over the previous year. Bayne and his team processed the Edmonton data and concluded that with approximately 300,000 homes in the study area the death toll for birds from window strikes might reach 180,000 per year.
