“How many birds are killed by windows?” Asks BBC’s Charlotte McDonald. While I doubt anyone will truly know, she reports any data she finds. Even goes back to the 90’s for some numbers. While also stating, “In 2004, Toms told the BBC the three major causes or bird deaths were: “Cats, collisions with cars, and collisions with garden windows.” ” While it’s great that she wants us to be aware, we are given nothing useful. No tip on prevention, just big numbers to freak us out. I myself can only come up with taking the windows out (which is now a safety hazard in most areas because of crime) or replacing the windows with wooden shutters so they don’t assume they can fly through it. Now if Treehugger had posted this, I bet they would have some pretty interesting thoughts.
