More about birds and windows

Following my last blog post about helping birds avoid collisions with windows, I heard from Dr. Krista De Groot, a landbird biologist with the Canadian Wildlife Service studying bird window collisions. She told me that her University of B.C. team’s research confirms that Varied Thrushes are highly susceptible to hitting glass and have a much greater proportion of window collision deaths relative to their abundance. Here are her additional suggestions for making windows safer for birds:

Where possible, for greatest effectiveness:

  • place markers on the outside of the glass surface;
  • place markers across the entire surface of the glass with gaps less than 5 – 10 cm

She suggests checking out FLAP Canada’s information and their Homeowner Brochure.

Feather Friendly and Ornilux glass are two possible commercial solutions for glass windows in high risk areas. Effectiveness will depend on the location and species of birds in the area, so we would advise researching the topic well before making an expensive decision.

How to Make Your Windows Safer for Birds

Thu, 2017/10/12 - 10:18am

Wintering Varied Thrushes are highly susceptible to suburban window kills in the Pacific Northwest. They often feed at dawn and dusk.

If you keep your windows squeaky clean, it can often be difficult for animals on the outside to distinguish between where the garden ends and the house begins. This can lead to the unfortunate danger of birds flying directly into the window. While this doesn’t always result in the bird’s death, it usually stuns the bird by impact and can lead to serious health issues like internal bleeding or brain damage.

Since the general bird population is on the decline, it is increasingly important that we do our part in making sure that our windows are visible to birds. Adding any visible decorations, like external shutters, decals, or windchimes, are all great ideas to make the outside of the windows more obvious to birds. Additionally, if you are installing new windows, you may want to consider the type of glass that you select. Certain types of glass can reduce the chances of window strikes, including:

  • Angled glass
  • Fritted glass
  • UV reflective glass
  • Etched or sandblasted glass

By being aware of the methods to make windows bird-friendly, we can eliminate the dangerous risk of birds colliding with windows and protect their population from unnecessary harm.

SALLY PERKINS is the Content Manager for a small window cleaning service and felt it was important to cover this topic. Her guide (see link) looks at how windows are impacting birds and how to make simple changes to help protect thousands of birds.
