Dead Yellow-billed Cuckoo.  Found August 2007 by WVAS member Marty Jones at the glass entrance to Lost Creek Elementary School in Terre Haute, Indiana.  The U.S. Fish and Wildlife Agency has estimated 100 million birds die annually in the U.S. due to building collisions.  

The guidelines were originally developed by New York City Audubon in 2007.  This 2010 version was produced by Minnesota Audubon and is presented in two parts.
