Cirl Bunting Welfare and Recovery in the UK

The cirl bunting is a conservation success story in Devon, but remaining birds face ongoing welfare risks from agricultural practices and climate change.

Key Facts

• Cirl buntings were reduced to just 118 pairs in the UK by 1989 but have recovered to over 1,100 pairs
• Recovery was driven by targeted agri-environment schemes providing winter stubble and mixed farming
• Cirl buntings are sedentary, making local food and habitat availability critical for welfare
• Insects for chick food are essential from May to August — their absence causes chick starvation
• Climate change threatens insect availability during breeding, posing new welfare risks

Welfare Considerations

The cirl bunting recovery demonstrates that targeted habitat management can restore both populations and individual welfare outcomes for declining farmland birds. However, the welfare of remaining individuals remains sensitive to agricultural practices and weather. Cold, wet summers reduce insect availability and cause high chick mortality. Adults face winter starvation risks when stubble fields or weed-rich margins are unavailable. Continued participation in agri-environment schemes, particularly those providing winter stubble, rough grassland margins, and reduced insecticide use, is essential to sustain the welfare gains achieved through recovery programs.

What You Can Do

• Support RSPB and local partnerships working on cirl bunting recovery in Devon and Cornwall
• Advocate for agri-environment scheme funding that maintains winter stubble and mixed farming
• Reduce insecticide use in areas near cirl bunting territories to preserve insect prey
• Record cirl bunting observations through BTO citizen science surveys
• Support climate policies that mitigate the insect declines threatening chick food supply
