Bird-window collisions

Posted Friday 30th January 2009 at 18:05 by ACO
My name is Peter G. Saenger and I work at the Acopian Center for Ornithology, Muhlenberg College, Allentown, Pennsylvania, USA, with Dr. Daniel Klem, Jr., who has been studying birds striking sheet glass and plastic for over 35 years. One of our goals is to compile a comprehensive list of all species known to have collided with sheet glass or plastic (excluding birds fighting their own reflection) world-wide, country by country if possible.

As of today, 30 January 2009, the world list stands at 813 species.

We lack records from many areas and would greatly appreciate any that you could add. It would be best to have dates and location data for strikes, but simple lists of species will be appreciated if that is all that are available. These can be sent via e-mail, spread sheets, via our forms on-line at our web site (see link below), or regular mail if necessary.

You can see what species we have currently and also research papers and more if you visit our web site (link below). Go the "Birds and Windows"

Most sincerely,

Peter G. Saenger

Peter,
Thought you might like to know that the website link did not work, but I found the "Birds and Windows" page here:
http://www.muhlenberg.edu/depts/biol.../GlassHome.htm

We have rarely had a window strike at our home - the windows are made up of individual panes, measuring 13"x11", not sheet glass, but on Jan 30th an American Goldfinch hit the kitchen window with such force, I was sure it was dead when I checked and found it lying on the lawn below. Fortunately it was only stunned and sat on my husband's finger for a few minutes before flying off to the nearest tree. We have a Cooper's Hawk in the neighborhood and this may be what spooked the goldfinches that morning.

I posted a photo of it in the Bird Forum Gallery, here: http://www.birdforum.net/gallery/sho...p/photo/233370

Hello Helen,
Thank you for the news on the link- here it is again to make it easy:

Hopefully is will work now.

Keep in mind that research has shown that 50% of all window collision prove fatal to the bird, even though the appear ok and fly away. Sad, but true. That said, 50% survive.

Thanks again and please send any records that you have in the future- our on-line form is very easy and come directly to me.

Thanks again,

Peter
