Bird Protection Marker for Windows 25m Roll SEEN Elements

SEEN Elements bird protection markers

Help make your windows safer for birds without compromising your view. Every year, millions of birds collide with glass because they cannot recognise it as a barrier. SEEN Elements bird protection markers make windows visible to birds while remaining discreet for people, offering a simple and highly effective way to reduce collisions around your home.

Why birds collide with windows

Birds often mistake reflections of trees, sky and vegetation for real habitat. As a result, they may fly directly into windows and glass doors. Adding visible markers to glass helps birds recognise the surface and avoid dangerous impacts.

Scientifically proven protection

SEEN Elements uses a carefully tested 9/90 mm grid pattern, with 9 mm aluminium dots positioned 9 cm apart. This design makes glass clearly visible to birds while covering less than 1% of the window surface, allowing you to maintain natural light and unobstructed views.

The effectiveness of SEEN Elements has been independently tested multiple times in the flight tunnel at the Biological Station Hohenau-Ringelsdorf in Germany. The system achieved a Category A classification with a collision rate of less than 10%, making it one of the most effective bird protection solutions available.

Easy to apply

The aluminium markers are supplied on a convenient roll of adhesive tape, making installation quick and straightforward. Simply apply the dots to the outside of the glass to create a bird-friendly window surface.

The shiny/black version, which reflects on one side, is specifically designed for windows where birds approach from the outside only, such as:

• Kitchen windows
• Living room windows
• Bedroom windows
• Home office windows
• Conservatory and garden-facing windows
