For three hours on Friday evening, Madeira and neighbouring Porto Santo will go deliberately darker. Between 8pm and 11pm, residents, businesses, councils and hotels have been asked to switch off unnecessary outdoor lighting so that thousands of young shearwaters — known locally as cagarras — can make their first flight from inland nests to the ocean without getting lost.
The appeal comes from SPEA (the Portuguese Society for the Study of Birds), which explains the problem simply: artificial light pulls the fledglings away from the coast and towards towns, roads and lit-up resorts. Once grounded or disorientated over built-up areas, the birds face injury, exhaustion or death. A darker coastline, SPEA says, means more of them reach the sea alive.
The response has been broad. The municipalities of Funchal, Santa Cruz, Câmara de Lobos and Machico are all taking part, along with Madeira Airport and a handful of hotels, including INATEL Porto Santo Hotel, Grupo Cardoso and Hotel Quinta da Serra. For visitors on the island that night, the effect should be noticeable — dimmer streets, darker hotel facades and, if anything, better stargazing over the Atlantic.
The blackout is one night of a longer campaign. SPEA is running seabird rescue efforts until November 5, using volunteers to collect grounded, confused birds and release them safely. It has also launched the 'Noite Com Vida' award, recognising businesses that adopt wildlife-friendly outdoor lighting — think shielded, warmer, lower-intensity fixtures. The whole effort sits under the EU co-funded LIFE Natura@night project, which tackles light pollution across Atlantic and Mediterranean island territories.
For travellers, this is worth knowing if you are heading to Madeira in autumn, when the shearwater fledging season peaks. If you find a young seabird sitting in a street, garden or car park — often looking tame or stunned — don't pick it up and leave it; the advice is to contact local rescue teams or SPEA volunteers, who know how to handle and release the birds. And if you're staying at a hotel, a simple gesture like drawing curtains at night and switching off balcony lights genuinely helps.
There is a wider appeal for holidaymakers here too. Madeira is one of the best places in Europe to see shearwaters and other seabirds, with boat trips from Funchal and coastal viewpoints where the birds pass in their hundreds. The island's tourism industry joining the blackout — hotels included — shows how conservation and visitor experience can point in the same direction: darker skies are better for the birds, and frankly better for anyone who came for the stars rather than the streetlights.
