Bird-safe resources

For maximum effectiveness, collision deterrent techniques and materials must strictly adhere to specifications that reflect current science and improved testing methods. Older resources may cite outdated criteria based on previous incorrect assumptions. Any deviation from current accepted standards may result in unacceptable risk to birds, requiring further measures (and costs) to mitigate collisions. 

UV-products, including stickers, films and UV-glass are currently NOT recommended.
