Feather Friendly Window Marker Tape


Anti-collision window tape with a high-contrast marker-pattern technology. Alerts birds to the presence of a window or glass surfaces with an aesthetically pleasing design. Developed in collaboration with FLAP Canada, this is the most efficient product to reduce window collision. 1 roll (100 ft.) protecting a 30" X 80" (0.8m x 2m) glass surface. Will not damage glass surfaces.

Available in Black or Grey depending on the glass


FF Black - For Fly-Through Glass

Fly-Through happens when birds see habitat or sky that really does exist but do not understand the glass is there as a solid barrier preventing them from reaching the other side. Transparent railings are a perfect example. If your glass has Fly-through, you will need our Black Deterrent Markers, and they can be placed on either side of the glass.

FF Light Grey - For Reflective Glass 

Reflection is when the surrounding habitat and sky are mirrored on the glass, causing the illusion of an environment that does not exist. If your glass has reflection, you will need our Light Grey Deterrent Markers and must be placed on the outside surface to be effective - the surface where the reflection is happening.


Window Safety

Window collisions are one of the main causes of injuries seen at Le Nichoir. House windows are responsible for an estimated 15 to 30 million bird deaths every year in Canada while tall buildings cause an estimated average of 64 000 deaths every year.
Please note that all window safety items will only work if placed on the outside of the window as the reflection causing the birds to mistake the glass for their habitat happens on the outermost surface of the window.
Please note that none of the window safety items sold will work in the situation where a bird is fighting with the window. In this situation, the bird is seeing its own reflection and believes it to be an intruder. If this is happening to you, please contact our bird helpline directly at 450-458-2809 or by email at
