Windows cause such a horrifying number of bird deaths a year that it boggles my mind. I got to spend some time with Dr. Daniel Klem three years ago. He's the Muhlenberg College Professor who has spent much of his career systematically studying bird mortality at windows, and I was trying to make 101 Ways to Help Birds as solid as possible as I amassed information about preventing window kills.
I'm working on a project right now that touches on window mortality, and so I'm getting some of my pages regarding the book back up on my website, starting with #6: Make your windows safer for birds. My original hope was that the book would be fully illustrated with color photos, and this section in particular would have been more valuable with photos illustrating some window treatments.
These photos and more are on my website, on the 101 Ways to Help Birds #6: Make your windows safer for birds. I'd been trying to keep birderblog filled with useful links and photos, and in the coming weeks will be getting more of that information back up on my own website.
