– One billion birds die every year by flying into glass they can’t see. Like humans, birds don’t actually perceive glass. They don’t understand it, New York City Audubon Executive Director Kathryn Heintz tells Business Insider. “They don’t learn the way we do as young children the cues that a frame on a window or on a door probably means a solid. And maybe we’ve walked into a door once or twice and learned that lesson. To birds, ‘the reflection of a tree looks like a tree, and they’re flying straight into it,'” Heintz says. That’s why some cities—including New York City, which passed a bill in December requiring all new construction and renovation use bird-safe material below 75 feet—are taking action. Illinois Rep. Mike Quigley’s Bird-Safe Buildings Act passed in the House in July, and one German company, Arnold Glas, has been making bird-safe glass called Ornilux for decades. It’s coated with a patterned, UV-reflective glaze and is cut to fit window and building sizes. The glass is tempered and insulated to finish off the process and packed to ship worldwide. In one experiment, a 25-foot tunnel sends hundreds of birds through
