Our question this week comes from Brian Hohm in Calgary. As someone who has seen the aftermath of birds colliding with windows, he wanted to know whether there's any research on birds evolving to avoid such collisions.  

Janet Ng is a PhD student in the Department of Biology at the University of Alberta. She shares the findings of a 30-year study on cliff swallows.
