The American Bird Conservancy has been working to reduce the incidence of bird mortality from window collisions at the Powdermill Avian Research Center. Dr. Christine Sheppard has been at the forefront of this initivatie. Recently the Discovery Channel has taken interest in the project and produced a five-minute video on the work of ABC and the Carneige Museum of Natural History. Take a look at the video here. The collisions story starts at about the 6:45 mark and ends at the 12 minute mark.
