Over 270 species of birds in the United States and Canada have been documented striking windows, and each year millions of birds die from striking windows.
The Muhlenberg College in Allentown, Pennsylvania is working on project identifying bird window collisions and they would like you help. The college, however, is only looking for information on those birds not currently on their list of bird window strikes. The list of birds they have documented as striking windows is available on their website.
For more information on how to report a bird strike or for a list of birds already identified, check out their website:
For more information on how to prevent window strikes go to the American Bird Conservancy's website: http://www.abcbirds.org/abcprograms/policy/collisions/glass.html where you can download their brochure on what you can do to prevent window strikes.
