Building a #birdfriendly world requires both #innovation and attention to detail. At Feather Friendly, we proudly offer scientifically tested solutions for both retrofitting existing buildings and new construction projects. ✅ A critical factor in preventing bird collisions is the application of first-surface treatments—visual markers on the exterior side of the glass. This ensures that birds can perceive glass as a barrier at any time of the day, regardless of lighting conditions. ❌ Treatments applied to the interior surface are not as effective, as reflections and transparency can obscure these treatments, leading to unintended collisions. Also, while some glass products incorporate patterns or coatings to deter birds, not all meet the recommended standards for marker spacing and high contrast. The 2×2 rule, which suggests placing markers two inches apart horizontally and vertically, has been identified as an effective guideline to prevent collisions, especially for smaller species...
