UK Bird Populations Fall to Lowest Level on Record 2026

UK bird populations have fallen to their lowest level since records began, with nearly half of native species in decline. The shocking figures, produced by leading nature conservation bodies for the government, show that average populations across 132 native breeding species fell by 19% between 1970 and 2025. Farmland birds and seabirds have been the worst hit in recent years, prompting experts to call the findings “shocking and sobering.”

Key Takeaways

• 19% decline in average populations of 132 native breeding species since 1970.
• 45% of species have declined over the past five years, while only 27% have increased.
• Farmland birds and seabirds are among the worst affected groups.
• Turtle doves, tree sparrows, and swifts are experiencing severe declines.
• Conservation efforts are urgently needed to reverse the trend.

Which Bird Species Are Most Affected?

The latest data reveals alarming declines across a range of species. Turtle doves have fallen by more than half in just five years, showing no sign of recovery from the brink of extinction. Tree sparrows, wood warblers, and capercaillie have also seen significant average annual decreases between 2019 and 2024. Swifts, whose arrival marks the beginning of summer for many, have declined by about 25% in five years—an average of nearly 6% per year across the UK. Bullfinches have fallen at a similar rate nationally, and by an average of 11% per year in England.

Why Are UK Bird Populations Declining?

Prof Richard Gregory, head of monitoring at the RSPB, described the findings as “shocking and sobering.” He emphasized that birds are indicators of the way we’re looking after the countryside and the world around us. “We’re losing the birds that people are so emotionally connected to and want to protect,” he said. The decline is largely attributed to habitat loss, agricultural intensification, climate change, and pollution. Farmland birds have been hit hardest by changes in farming practices, while seabirds face threats from overfishing, plastic pollution, and rising sea temperatures.

Regional Differences

In England, 55% of monitored species have declined, a higher proportion than the UK average. This highlights the need for targeted conservation efforts across different regions.

What Can Be Done to Help?

Conservation organizations are calling for urgent action to reverse the decline. This includes creating and protecting habitats, implementing wildlife-friendly farming practices, and reducing pollution. Individuals can also help by providing food and water for birds, creating bird-friendly gardens, and supporting conservation charities.
