Gloucestershire Nature Reserve Installs Bird-Friendly Window Film
10 Nov, 2025
Summary
- UK nature reserve uses UV-active film to make windows visible to birds
- Estimated 100 million bird deaths annually from window collisions in the UK
- Slimbridge reserve proud to take action to protect its wetland bird population
As of November 10th, 2025, a nature reserve in Gloucestershire, UK has taken a significant step to protect its feathered residents. The Wildfowl & Wetlands Trust (WWT) Slimbridge has installed a special window film that makes the glass detectable to birds, preventing them from colliding with the windows.
This move comes in response to a major issue facing the UK's bird population. According to the British Trust for Ornithology, an estimated 100 million birds crash into windows annually across the country, resulting in a staggering number of fatalities. The new UV-active film technology used at Slimbridge allows the windows to remain almost clear to human eyes, while making them visible to birds, effectively tackling this problem.
Anna Cork, the reserve warden at WWT Slimbridge, expressed the organization's pride in taking meaningful action to safeguard the wetland birds that call the sanctuary home. "Slimbridge is a haven for these creatures, and we're committed to doing everything we can to protect them," she stated. The installation of this innovative window film is a testament to the reserve's dedication to the wellbeing of its avian residents.
