As urbanization accelerates and glass-covered high-rises proliferate, the phenomenon of "window strikes" has become a growing concern. In Taiwan, tens of thousands of birds collide with glass windows each year, resulting in countless deaths and posing a serious threat to the ecosystem.

Experts explain that the reflective surface of glass creates mirror-like illusions, which are the primary cause of bird strikes. Birds perceive these reflections as open space and attempt to fly through at full speed, often leading to fatal injuries.

Preventing window strikes requires surprisingly simple measures. Research from the U.S. indicates that adding small, evenly spaced markings to glass—such as rows of dot stickers no farther apart than the width of a credit card—makes the glass visible to birds. This straightforward solution has been shown to reduce collisions by more than 90%.

窗殺鳥 看不見的殺機

由於城市化進程加快，高樓大廈和玻璃幕牆的普及，使得「窗殺鳥」現象日益嚴重。台灣每年有數以萬計的鳥類因撞擊玻璃窗而喪生，這對生態系統造成了潛在的威脅。

醫師說玻璃的光滑面會產生鏡像反射，就是導致窗殺的主因。這對鳥類來說像是一個延伸的空間，導致鳥類誤認是可以飛過去，飛行不減速的狀態，導致癱瘓或是死亡。防止窗殺的方法其實不難，美國研究顯示，只要在玻璃上做一些簡單的記號，像是貼上排列規律的圓點貼紙，間隔需要小於一張信用卡的範圍，就能讓鳥類清楚辨識出玻璃的存在，避免誤闖，這種方法的防治效果可以達到九成以上。
