Striking out at bird-window collisions

April 1, 2017

While achieving that crystal-clear window during spring cleaning is visually pleasing for a homeowner, for birds, it’s hardly visible at all.

In Canada, more than 25 million birds are injured or killed by collisions with windows every year.

“Unfortunately there is no set season, day or time when birds are safe from window collisions. If we want to help, we should always be thinking about our feathered friends,” says Dr. Sara Dubois, chief scientific officer for the BC SPCA.

Window reflections deadly to birds

Windows have become one of the bird’s most costly threats, with more dying from striking them than collisions with power lines, communication towers or vehicles. Whether it’s a hummingbird, a migratory songbird or even a hawk or an owl, they are all victims of this unfortunate situation.

“Birds end up colliding into windows simply because they can’t see them,” Dubois says. “When the windows reflect the landscape or the sky, it can almost look like an inviting place to fly. This is a year-round hazard for birds, in all types of weather.”

Often, when birds survive a window collision, it will temporarily stun them and they will fly off, as if recovered. But, this is not always the case. In reality, the bird may die later from internal injuries or the bird will then be an easier victim to other dangers and predators.

How you can help

Luckily, there are easy steps to help birds from window strikes.

“To help prevent these often fatal incidents, try using WindowAlert™ decals or Feather Friendly® tape,” suggests Dubois. “The more coverage the better. By doing this simple change, you truly are saving lives,” said Dubois.

The decals or tape attach to the outside of your window to make glass more visible by reflecting UV light that birds can easily see and humans can’t, glowing like stop lights to  warn birds away.

Along with decals, hanging mylar strips or well-secured strings of beads can also be an effective and visually-pleasing solutions that helps birds avoid glass. If a bird happens to hit your window and is injured, it’s important to seek advice of experts rather than trying to provide care yourself.

“While it definitely feels great to save an animal’s life, do not attempt to give water, food or any other care to the bird,” says Dubois. “Birds need specialized care and attention, so calling your local wildlife rehabilitation centre is the best chance for the bird’s survival.”
