Wildlife Welfare

Wild Barn Swallow Farmland Insects Advanced

Barn swallows depend on aerial insects for food and face welfare consequences from agricultural intensification that has dramatically reduced insect abundance. Supporting insect-rich farming landscapes is essential.

Key Facts

UK barn swallow populations have declined by 46% since the mid-1970s
Swallows make up to 500 feeding flights per day when raising chicks
Insecticide use and habitat loss have reduced aerial insect abundance by over 50% in some areas
Swallows feeding chicks require large insects and must fly further in insect-poor landscapes
Organic and mixed farming systems support higher insect abundances than intensive arable

Welfare Considerations

Barn swallow chicks in areas with low insect abundance receive inadequate food and suffer from undernourishment during the critical growth period. Adult birds expend significantly more energy finding food in impoverished landscapes. Supporting farming systems that maintain insect-rich habitats directly benefits individual swallow welfare.

What You Can Do

Support organic and agri-environment farmers maintaining insect-rich habitats
Avoid pesticide use in gardens to support local insect populations
Advocate for insect abundance monitoring to be included in farm sustainability metrics
