TIPS AND TECHNIQUES FOR HOME AND COTTAGE OWNERS

Whichever technique you choose, apply it to the outside of your window. Make sure your chosen deterrent meets FLAP Canada Visual Marker Standards for spacing.

INSTALL EXTERIOR WINDOW SCREENING OR NETTING

Tightly stretch window screening or dense netting across the outside surface of your windows to cushion the impact should a bird fly into the material. Leave a minimum space of 5 cm (2 in) between the window and the netting or screen. Keeping it taut will also protect birds from getting tangled. In some cases, birds see the deterrent and avoid impact.

HANG RIBBONS OR STRING

Hang ribbons, parachute cords or other material 10 cm (4 in) apart, across the full width of the outside of your windows. The vertical lines create “visual noise” for birds and alert them to the presence of glass. This strategy is also suitable for certain commercial or industrial buildings. Keep in mind that the example shown does not meet FLAP Canada Visual Marker Standards. Increasing the number of streamers and moving the bird feeder closer to the window, a half metre (1.6 feet) or less, will increase the effectiveness of the collision deterrent.

GET CREATIVE!

Create “visual noise” for birds by affixing lightweight items from around your home on the outside of your windows (items that won't damage your windows, of course.) Here are a few ideas:

  • Used CDs
  • Pine cones
  • Sun catchers
  • Laminated pictures or photographs
  • Seasonal decorations
  • Costume jewelry or beads

USE YOUR WINDOWS AS A CANVAS

Be creative: draw images using a bar of soap or erasable marker on the outside of your window.

APPLY DECALS

Window decals can be any shape – birds, flowers, geometric patterns or others – as long as they are used on the outside of the glass in a dense pattern that minimizes the areas of exposed glass.

WHITEWASH YOUR WINDOWS

Whitewashing is an inexpensive, temporary alternative that is highly effective at reducing bird collisions with windows. Whitewash is easy to apply at the beginning of each migration season and easy to wash off at the end of each season.

IN ADDITION TO THE ABOVE TECHNIQUES...

RELOCATE YOUR BIRD FEEDERS

Position your bird feeders, birdbaths and other attractants half a meter (1.5 feet) or less from your windows. From this short distance, birds cannot build up enough momentum to injure themselves should they hit your window. This may seem counter-intuitive, but the closer the bird feeder to your window, the better for the birds and your viewing! What’s more, it provides entertainment for your housecats!

Protect your cat and wildlife by keeping your cat indoors. The image on the left beautifully captures 3 important messages: cats indoors, bird-safe markers applied to windows and bird feeders close to windows.

MOVE HOUSEPLANTS

If you can see your houseplants from the outside of your home, then so can the birds. Birds perceive your houseplants as a possible perch or refuge. Moving your houseplants back from your windows lessens this attraction.

CLOSE CURTAINS AND BLINDS

Close curtains and blinds to reduce the dangerous illusion of clear passage through windows, especially those that meet at corners, or where windows are situated in line with one another at the front and back of your home.

Exterior window awnings can also help mute window reflection and help protect birds from the illusion of a clear passage.

GARDEN FOR WILDLIFE

Plant native trees, shrubs and flowering plants in your yard to provide food and nesting areas for birds. Visit the North American Native Plant Society website for tips.
