Almost invisible to humans, these stickers are clearly seen as an obstacle thanks to a special UV coating for birds.
Birds’ eyesight is more diverse than ours, they can see a wider spectrum of colours, including ultraviolet light. Despite this detecting hazards such as clear reflective windows can prove a challenge for birds.
International research has found that UV markings on windows, spaced 5-10 cm apart, can reduce the likelihood of bird-window strikes.
There are five birdstickers in each pack.
Each sticker measures 18 x 11 cm.
