Bird Friendly Buildings

Birds face innumerable threats in our human built environment and our glass surfaces are one of the biggest.

During daylight hours, birds collide with reflective surfaces when they stop to feed or rest, when avoiding a predator or flying from tree to tree. Shiny glass exteriors, internal plants near windows, glass corners, and greenery close to buildings can all be deadly as birds are unable to distinguish reflection from open flyway. For every collision victim found, three more typically go unseen, flying out of sight before falling or being carried away by predators.

Window collisions are one of the leading direct human causes of bird mortality. A 2014 study by the US Fish and Wildlife Service and the Smithsonian Institution estimated that between 365 and 988 million birds are killed annually by building collisions in the U.S.

To determine the extent of the problem in our area and if there are any buildings that present a serious problem for birds we have developed this Bird Friendly Buildings section of our web site.
