Birds collide with windows for the simple reason that they do not see windows as solid objects, especially when windows reflect the sky or surrounding landscape. UMass Amherst, a hub for both architectural design and sustainability, is positioned along a migratory flyway and provides a perfect setting to examine and address this pressing issue. This exhibit is about the science of bird-window collisions, and the architectural solutions that offer some hope for interspecies benefit in the face of global bird declines.
