Each autumn, a remarkable transformation takes place on the small island of Corvo in the Portuguese Azores. Rather than a result of an emergency, a planned blackout plunges the island into darkness for five consecutive nights during the end of October. This deliberate act of community care is designed to protect some of the world's most vulnerable seabirds as they embark on their very first journeys to the open ocean.
Protecting Cory's Shearwater Fledglings
During this critical time of year, young seabirds such as Cory's Shearwaters leave their nests to head out to sea. To evade natural predators, these birds make their maiden voyages under the cover of darkness. However, artificial light from towns and cities frequently disorients them. Blinded by urban glow, thousands of fledglings become grounded across the Azores, Madeira, and the Canary Islands each year.
Recognizing the severity of the issue, the 400 residents of Corvo unite with local authorities and conservation organizations to turn off all public lighting from 9:00 PM to 4:00 PM during the peak fledging week. This proactive measure has garnered unanimous community support, proving that small towns can make a massive difference for local wildlife.
Community Action and Conservation Success
- Massive Rescue Efforts: More than 30,000 Cory’s shearwater fledglings have been successfully rescued in the Azores since 2015, with about 6,000 saved on Corvo alone.
- Dedicated Volunteers: Dozens of local volunteers step up every year, safely guiding disoriented birds back to the sea using simple tools like cardboard boxes.
- Regional Impact: Initiatives like the Interreg LuMinAves and Interreg EElabs projects are working to expand sustainable lighting practices across other islands and municipalities.
A Brighter Future for Wildlife and Energy Efficiency
The Azores archipelago serves as an essential global habitat, hosting roughly 65% to 75% of the entire world’s breeding population of Cory's Shearwaters. By lowering energy consumption and eliminating unnecessary outdoor lighting, communities are not only safeguarding endangered seabirds but also embracing sustainable energy policies.
Conservation campaigns continue to mobilize volunteers and educate local businesses and institutions on the importance of dark skies. By following Corvo's shining example of coexistence, island communities throughout the region are helping thousands of young birds reach the water safely year after year.
