Visual markers that save birds.
Feather Friendly® is the industry-leading bird collision deterrent visual marker system. Tested by the American Bird Conservancy and Dr. Daniel Klem Jr., with documented 95%+ reduction in bird-glass collisions across thousands of buildings worldwide.
95% +
collision reduction documented in independent studies of professionally installed Feather Friendly visual markers.
Tested by American Bird Conservancy, Dr. Daniel Klem Jr., and FLAP Canada — meeting and exceeding bird-safe standards worldwide.
A scientifically tested visual marker system — not a film.
Feather Friendly is a bird collision deterrent solution made up of small visual markers that get applied directly to glass. Only the markers remain on the surface — the rest of the glass stays optically clear.
This is the most important detail to understand: Feather Friendly is not a full-film application, tape, or decals. The markers are precisely positioned dots that birds can see, but that don't compromise the building's appearance, energy performance, or sightlines from inside.
Available in white for reflective glass and combination glass surfaces, and black for fly-through glass surfaces, Feather Friendly comes in 10 standard patterns plus customizable designs and colors for projects with specific aesthetic or specification requirements.
Manufactured by Feather Friendly® Bird Collision Deterrent Technologies Inc. since 2006, with installations worldwide in 48+ countries.

Three steps from invisible to bird-safe.
Visual markers turn previously invisible glass into a surface birds can detect — without changing how the glass looks or performs for the people inside.
1. Site Evaluation
American Window Film evaluates your building — identifying the highest-risk elevations, glazing conditions, and surrounding landscape that drives bird strikes.
2. Marker Application
Visual markers are precisely applied to the exterior of the glass following tested spacing patterns. The markers are durable, weather-resistant, and designed to last 20+ years.
3. Birds See, Birds Avoid
Birds perceive the marker pattern as a barrier they cannot fly through. Independent studies show 95%+ reduction in collisions on glass treated with Feather Friendly.

Feather Friendly — answered.
Common questions from facilities teams, architects, designers, and homeowners evaluating Feather Friendly visual markers.
What is Feather Friendly?
Feather Friendly® is a scientifically tested bird collision deterrent visual marker system. The markers are applied directly to the glass surface — only the markers remain on the glass, not a full-film application. Manufactured by Feather Friendly® Bird Collision Deterrent Technologies Inc. since 2006, with installations across 48+ countries.
Can Feather Friendly be installed on existing glass?
Yes. Feather Friendly is a retrofit-friendly solution. The markers can be applied to existing glass on commercial buildings, schools, healthcare facilities, condo and apartment buildings, and homes — without replacing glazing or affecting the glass’s thermal or structural performance.
How effective is Feather Friendly at reducing bird collisions?
Independent studies have documented 95%+ reduction in bird-glass collisions on Feather Friendly Pro installations. Feather Friendly is tested and approved by the American Bird Conservancy, Dr. Daniel Klem Jr., FLAP Canada, and other conservation organizations worldwide.
Is Feather Friendly only for commercial buildings?
No. Feather Friendly is used on both commercial and residential properties — especially homes with large reflective windows facing wooded yards, gardens, or open sky. Bird strikes are a real issue on residential glass, particularly during migration seasons.
How long does Feather Friendly last?
Feather Friendly Pro is rated to last 20+ years — over 40 bird migration cycles — backed by a 15-year warranty. The markers are PFAS-free and can be installed in temperatures as low as -20°C, allowing for year-round installation in colder climates.
Does Feather Friendly support LEED and other sustainability programs?
Yes. Feather Friendly supports LEED bird collision deterrence credits and aligns with the BIRDS protocol, USGBC standards, and many municipal bird-friendly building ordinances. American Window Film provides project documentation for certification paths.
