Glass can be a tricky illusion for birds, reflecting open sky, trees and garden greenery. These bird window stickers help break up reflections and make windows more visible, reducing the risk of birds flying into the glass. Each a4 sheet includes 5 black bird silhouette stickers in different flight shapes. Place them on windows, patio doors, conservatories or glass panels to help birds recognise the surface as a barrier rather than open air.
