UK Barn Swallow Conservation and Climate Impacts

Conservation of barn swallows facing climate-driven changes to their migration and breeding success.

Key Facts

Barn swallow populations are under increasing pressure from climate change
Earlier springs shift insect emergence before swallows arrive from Africa
Drought in African wintering grounds reduces survival during the non-breeding season
Swallows require access to farm buildings and need wet areas for mud nest building
UK swallow population has declined by around 40% since the late 1990s

Welfare Considerations

Individual swallows face welfare pressures from climate-driven mismatches between migration timing and insect availability, with direct welfare impacts on breeding adults and chicks.

What You Can Do

Maintain access to farm buildings and outbuildings for swallow nesting
Create muddy areas near water for swallow nest material collection
Support climate action as a long-term animal welfare strategy
