The scale of the problem

More than one billion Bird-glass collisions occur in the U.S. each year.

Most fatal collisions happen at homes and buildings under four stories. This is a problem we can start addressing at home.

01 / ASSESS

See what matters.

Upload a photo and answer a few questions about reflections, nearby habitat, and existing treatments.

02 / VISUALIZE

Explore the possibilities.

Preview closely spaced bird-friendly patterns directly on your window, from subtle dots to decorative shapes.

03 / ACT

Leave with a plan.

Turn your design into an approximate layout and print a clear, personalized action plan.

Why glass is different

It looks like a way through. It isn’t.

To a bird, a window can reflect open sky or a stand of trees. Light shining through glass at night can create another hazard. Making the surface visible helps birds recognize a barrier.

Read the evidence

Reflections can resemble habitat

Sky, vegetation, and nearby landscaping can draw birds toward the glass.

Lighting changes the picture

Unnecessary nighttime light can also contribute to collision hazards.

Make it yours

Bird-friendly can be beautiful.

Choose a treatment that works with your home. PaneGuard previews repeated, closely spaced marks so the whole pane becomes easier to recognize.
