Even though he grew up in an urban area surrounded by buildings, it wasn't until Omar Yossofzai took part in a study on migratory birds that he realized how many birds die daily after crashing into buildings.

The fourth-year undergrad led a group of U of T Scarborough students to track fallen migratory birds colliding into campus buildings over a 21-day period last fall.

The group was part of a massive North American study looking at the number of birds crashing into windows. Altogether, 40 colleges and universities across North America were involved in the project with U of T Scarborough being the only contributor of data from Toronto and southern Ontario, which falls in an important migratory corridor for birds.

Researchers found that large buildings in areas of low urbanization – those surrounded by vegetation like forests and gardens – had a higher collision rate than large buildings in areas of high urbanization, like those surrounded by other buildings or parking lots.
