Barn Swallow Welfare and Farm Management

Barn swallows rely on open farm buildings for nesting and pasture farmland for insect food, making their welfare intimately linked to farming practices.

Key Facts

UK swallow population declined 36% since 1970
Swallows nest on beams and ledges inside farm buildings
Access holes into traditional barns must remain open during breeding season
Insect food for chicks comes from cattle pasture and damp areas near water
Swallow population correlates with livestock numbers on mixed farms

Welfare Considerations

Modernisation of farm buildings blocks nest access, while conversion to arable reduces insect prey availability. Each closed barn door can eliminate a breeding pair. Farmer engagement in keeping barn doors open is a direct welfare intervention with measurable impact.

What You Can Do

If you manage farm buildings, keep access open during swallow breeding season
Install ledges in farm buildings as artificial nest supports
Support mixed and pastoral farming that maintains insect prey for swallows
Participate in BTO's Nest Record Scheme to monitor swallow breeding success
