Do wind turbines kill birds? Safeguarding climate and nature
- Published 30 September 2025; updated 30 September 2026; estimated reading time 3 minutes. The article says bird deaths at wind farms result mainly from collisions with rotating blades, which may be difficult to see in fog/low light, and with associated high-voltage power lines. It cites estimates ranging from hundreds of thousands of deaths in the US to millions worldwide, while acknowledging that estimates vary and rapid build-out could raise totals.
- Species identified as vulnerable include large raptors (eagles, hawks, vultures), migratory songbirds and seabirds, particularly where turbines overlap migration routes or important nesting, feeding or wetland habitat. Risk depends on location, local bird communities and turbine design/spacing.
- Mitigation measures described include site assessments and siting away from migration routes/eagle territories; temporary shutdown during migration or when large birds are detected; and blade-painting. The article cites studies in Norway and the UK reporting about 70% fewer bird collisions when one blade is painted black.
- Monitoring options include radar, acoustic systems and thermal cameras. Norwegian startup Spoor is profiled for AI/computer-vision monitoring that detects birds remotely and identifies species. The article says its data can inform pre-construction design and ongoing shutdown decisions, while reducing reliance on short, weather-limited human surveys. Spoor CEO/co-founder Ask Helseth says the monitoring is useful across the wind-farm lifecycle.
- The article argues that wind power can reduce broader biodiversity pressures by displacing fossil fuels, but says cumulative turbine deaths still require careful siting and active safeguards.
