Bird Collision Deterrent Markers

Large-Scale Pro

Project size recommendation: > 150 sqft

Feather Friendly’s Large-scale Pro product line offers an easier install as you are able to lay 3ft widths of markers at a time. It is recommended for projects of over 150 sq.ft. and has a durability and longevity of 15+ years. For customization options and product details, view our product comparison chart below.

Our Large-scale Pro product is not a full-film application, meaning only the markers remain on the glass. This promotes visibility while effectively breaking up the reflective or fly-through danger. There is no solar load concern, as our markers only cover 6% to 8% of the 
glass surface

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, 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.

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 a reflective issue with the white markers on the first surface side (exterior surface).
