Wild Barn Swallow Chick Welfare

Barn swallow chicks in UK farm buildings face welfare risks from nest failure, food shortage and renovation disturbance, requiring sympathetic farm building management.

Key Facts

Barn swallows raise 2-3 broods per season, with chicks fledging after 18-23 days in the nest
Insect availability determines chick growth rate and survival - food-stressed chicks may not fledge
Nest disturbance by farm activities causes nest abandonment and chick mortality
Chemical fly control in farm buildings reduces the insect food supply for swallow chicks
Farm buildings with open access and undisturbed rafters support highest breeding densities

Welfare Considerations

Barn swallow chick welfare is directly linked to insect availability and nest site security. Farm management decisions have direct welfare consequences for individual birds.

What You Can Do

Maintain open access to farm buildings used by nesting barn swallows
Avoid chemical fly control inside buildings with nesting swallows
Record swallow breeding attempts to contribute to national monitoring
