Wild Birds Unlimited – East Lansing and Okemos stores have WindowAlert static-cling decals that contain a component which brilliantly reflects ultraviolet sunlight.
This ultraviolet light is invisible to humans, but glows like a stoplight for birds. WindowAlert decals help birds see windows and avoid striking the glass. To the human eye, the decals appear as frosted or etched glass.
WindowAlert decals come in many shapes including leaves, hummingbird, butterfly, hawk and snowflake.
If you do have a window strike and the bird is injured CALL FOR ADVICE! The best course may be no interference. For a list of licensed rehabilitators click HERE. Or visit the Michigan Department of Natural Resources at: http://www.michigandnr.com/dlr/
