PNW strives to reduce light pollution to protect migratory birds

As millions of birds prepare to migrate through Portland along the Pacific Flyway, city officials are urging residents to reduce light pollution by turning off or dimming their outdoor lights. This initiative aims to help protect migratory birds, which rely on the moon and stars for navigation but can become disoriented by city lights.

Why it matters

Urban light pollution has been found to pose a significant threat to wildlife, especially birds. It can disrupt their natural sleep cycles, alter migration patterns and in some cases lead to collisions with buildings or other structures. Since the 1970s, the North American bird population has declined by 30%, underscoring the need for protective measures during key migration periods.

The last news

In response to these growing concerns, the Portland City Council last week adopted a proclamation, championed by the Bird Alliance of Oregon, calling for darker skies during the spring migration period, which lasts until May 19. The proclamation encourages residents and businesses to minimize light. pollution by turning off unnecessary outdoor lighting or directing it downwards to reduce its impact.

What the city asks

The city recommends that Portland residents turn off security lights, yard lights and other outside lighting that could attract birds. Participation in the initiative is voluntary, but several city buildings are leading the way by joining Lights Out Portland. This includes City Hall, the Portland Building and several Portland Parks & Recreation community centers.

The Importance of the Pacific Flyway

The Pacific Flyway is one of four major bird migration routes in North America, bringing millions of birds through Portland’s skies every year. Reducing light pollution during the migration period can make a significant difference in ensuring the safe passage of these birds.
