Barn Owl Conservation and Rodent Control Alternatives

How protecting barn owls and other raptors provides natural rodent control while eliminating rodenticide welfare harms.

Key Facts

A single barn owl family consumes over 3,000 rodents per year, providing substantial natural pest control.
Barn owl populations have declined by over 70% in the UK since the 1930s due to habitat loss and rodenticides.
Nest box programs have been highly effective at restoring barn owl populations in agricultural landscapes.
Secondary rodenticide poisoning from consuming poisoned rodents kills thousands of barn owls annually.
Farms using barn owl conservation programs can reduce rodenticide use by 70-100% in some contexts.
Barn owls are highly site-faithful, returning to the same barns and boxes year after year.

Welfare Considerations

Barn owl welfare intersects directly with agricultural rodent management practices. Rodenticides cause secondary poisoning in barn owls and other raptors that consume poisoned rodents, creating welfare harms including hemorrhage and coagulopathy before death. Transitioning to barn owl conservation programs eliminates these harms while providing effective rodent management. Nest box installation requires attention to placement, entrance design, and protection from predators and human disturbance. Agricultural policies that support raptor-friendly farming through agri-environment schemes provide the systemic change needed to restore barn owl populations at landscape scale.

What You Can Do

Install and monitor barn owl nest boxes on rural properties following species-appropriate guidelines.
Switch from rodenticide to snap traps and habitat modification to protect barn owls from secondary poisoning.
Support agri-environment schemes that include barn owl habitat and nest site provision.
Report barn owl sightings to monitoring programs that track population recovery.
