What is Feather Friendly®

Feather Friendly® Bird Collision Deterrent Markers make glass visible to birds, with a durability and longevity of over 15 years. We are tested and approved by American Bird Conservancy, Dr. Daniel Klem Jr., and supported by countless other organizations.

While every project is unique, independent studies have shown a 95%+ reduction in bird-glass collisions.*

Feather Friendly® successfully prevents collisions by following the leading scientific guidelines required for a solution to be effective.

White Markers for Reflective and Combination Glass

Reflective glass creates the illusion of additional habitat a bird thinks it can reach. It must be treated with a high-contrast hue, like our white markers on the first surface side (exterior surface), which stand out against the green and brown shades of the habitat.

Black Markers for Fly-Through Glass

Fly-through glass happens when birds see greenery and/or sky on the other side but do not understand the glass is there as a barrier preventing them from reaching it. Bus shelters, clear railings, and walkways between buildings are just some examples of fly-through glass.

Fly-through glass must be treated with a high-contrast hue, like our black markers, which stand out against the light shades of the sky and clouds.

Have both glass issues? (Combination Glass)

If you have both fly-through and reflective glass issues, we recommend treating it as 
you would reflective glass with white markers on the first surface side (exterior surface) or, whichever side you are seeing the most strikes happen on.
