![]() It also can draw them into urban areas where they can face hazards, like crashing into windows. Light pollution can disorient birds, causing them to exhaust themselves. “A lot of birds migrate at night and it blocks out the stars. “Light has serious impacts on migration,” Sallinger said. The lab forecasts bird migration patterns across the country and suggests varying levels of lights-out alerts based on how many birds are passing overhead. The Audubon Society shared a “lights-out alert” on Tuesday, based on data published by Colorado State University’s AreoEco Lab. “You can’t see them at night, but the sky is literally full of birds,” Sallinger said Most of their journey happens after the sun goes down. ![]() “We’re talking about songbirds, we’re talking about waterfowl, we’re talking about birds of prey,” said Portland Audubon Society conservation director Bob Sallinger. State legislative action can be taken to reduce collisions and address the two leading building design issues.During migration season, millions of birds fly though Oregon as they head north for the summer. Measures like these also benefit humans, as they reduce the burden of light pollution on BIPOC communities, who receive disproportionate exposure. The Lights Out Initiative and use of UV light censoring windows are two strategies that are successful in reducing collisions. Artificial lighting is the second leading factor as it disorients tired, migrating birds during their night time travels. ![]() Decals and coating or partitionings can be used to distinguish windows from the environment. First is the “window effect,” where birds see landscape reflections in windows and assume it is a safe area to fly. ![]() ![]() Bird-safe buildings mitigate this issue by addressing two building design flaws. Bird-building collisions kill between 365-900 million birds per year. ![]()
