This was a heartrending discovery during my stay at Claybank. This little common yellowthroat warbler (Geothlypis trichas) died when it collided with a window. The National Audubon Society estimates that between 300 million and one billion birds die in collisions with glass in the United States each year, with about 45 percent of the collisions occurring at low-rise residences.
