New research reveals that decals intended to reduce incidents of bird window strikes — one of the largest human-made causes of bird mortality — are only effective if decals are placed on the outside of the window. Researchers found that the patterns on the films and decals placed on the internal surface of windows do not reduce collision because they may not be sufficiently visible to birds.
