Calgary Group Urges Lights Out to Protect Migrating Birds This Spring
As the spring migration season approaches, a local environmental organization in Calgary is calling on the community to take a simple yet impactful action: turn off non-essential lights at night. Bird Friendly Calgary has launched a campaign urging homes and businesses to dim or switch off exterior and interior lighting between March 20 and May 31, 2026, to help safeguard avian species during their perilous journeys.
The Dangers of Light Pollution for Birds
Bird migration is a critical natural phenomenon, with millions of birds traversing North America each spring and fall. However, artificial light at night poses a significant threat to these travelers. Bright lights can disorient birds, causing them to collide with buildings, windows, and other structures, leading to injuries or fatalities. According to research, light pollution contributes to an estimated hundreds of millions of bird deaths annually across the continent, making it a pressing conservation issue.
Bird Friendly Calgary emphasizes that even small changes can make a big difference. By reducing unnecessary illumination, particularly in urban areas like downtown Calgary, residents can help create safer flyways for species such as warblers, sparrows, and waterfowl. The group points out that migration periods are especially vulnerable times, as birds are often exhausted and more susceptible to hazards.
Community Action and Broader Implications
The campaign is part of a growing global movement to address light pollution and its effects on wildlife. In Calgary, the initiative aligns with broader environmental goals, including efforts to promote urban biodiversity and reduce energy consumption. Bird Friendly Calgary is encouraging participation through social media outreach and partnerships with local businesses, suggesting alternatives like motion-sensor lights or shielded fixtures that direct light downward.
Experts note that protecting migratory birds has cascading benefits for ecosystems, as birds play vital roles in pollination, pest control, and seed dispersal. The call to action comes amid increasing awareness of human impacts on nature, with many cities worldwide adopting "lights out" programs during peak migration times. By joining this effort, Calgary can contribute to a larger conservation network while fostering a more bird-friendly urban environment.
As the 2026 migration season unfolds, Bird Friendly Calgary hopes to see widespread community engagement, turning the city into a beacon of hope for our feathered friends. With collective action, even something as simple as flipping a switch can help ensure that birds continue to grace our skies for generations to come.
