Window strikes can happen any time of the year, but particularly when birds are migrating during the spring and fall. We get a lot of calls about birds hitting windows. The caller may have seen the bird hit the window, or found a bird in the area of a window showing signs of a loss of balance or unable to fly and collision seems the most logical reason.
If you find a bird that you believe is a victim of a window strike and is not showing symptoms of swelling , drooping wings, or blood, which demands immediate attention by a wildlife rehabilitator, you should contain the bird in a box and place them in a safe quiet area for an hour. If the bird is just stunned it needs a stress free environment to recover. After an hour check on the bird. You should hear fluttering inside. Take the bird to an open field or ravine area away from windows and buildings, open the box and let the bird fly away. If the bird is still unresponsive after one hour keep him a quiet area. At this point head trauma is the most likely diagnosis, a wildlife rehabilitator should be contacted right away for treatment.
Window strikes devastate bird populations. “Ornithologists now claim that bird collisions with human-built structures is a leading cause of bird death across North America.” Birds only see the reflection of their habitat (trees, water, sky or the potted plant in your window) they cannot see the glass.
Bird attractants such as feeder, trees, bushes, flowers can attract birds to your yard. This can make them vulnerable of running the risk of colliding with reflective glass. There are techniques that can reduce the threat of collision that FLAP Canada recommends, Patterned window film, window curtain, perforated window film, window screen, and a special product called CollideEscape (link provided below.) Products such as Hawk Silhouettes, Single Window Decals, Noise Deterrents, Plastic Owls etc. do not work in deterring birds. For more information on how you can protect birds from window strikes please visit FLAP Canada. An organization that is dedicated to raising awareness about how to avoid window strikes and protect bird through migratory seasons by supplying science based information as well as working with business’ and the community.
