Wild Barn Swallow Population Decline: Conservation and Welfare

UK barn swallow populations have declined significantly, with habitat changes reducing both breeding success and individual welfare.

Key Facts

UK barn swallow populations declined by 46% between 1970 and 2019
Loss of nest sites through barn renovation and farm building access restrictions reduces breeding opportunity
Insect prey decline from agricultural intensification limits food availability for chicks
African wintering ground habitat loss is an additional pressure on the population

Welfare Considerations

Swallow chicks that starve or fail to fledge due to inadequate food provision experience acute suffering. The decline affects both individual welfare and population viability. Maintaining nest site access in farm buildings and restoring farmland insect populations address the two most significant UK pressure factors.

What You Can Do

Provide nest site access in farm buildings through open windows or ventilation gaps
Support organisations tracking swallow migration to identify African wintering ground pressures
Advocate for farmland insect restoration through agri-environment schemes
