Kestrel and Barn Owl Welfare: Farmland Raptors in Crisis

Kestrels and barn owls depend on farmland ecosystems for survival. Agricultural intensification, rodenticide poisoning, and habitat loss are driving their welfare crisis across the UK.

Key Facts

UK kestrel populations have declined by 36% since 1995, making them an amber-listed species of conservation concern
Barn owl populations are more stable but face ongoing threats from rodenticide poisoning and road casualties
Kestrels hunt voles from hovering flight, requiring open areas with rough grass and plentiful small mammals
Barn owls are killed in large numbers on roads — an estimated 3,000-5,000 annually in the UK
Second-generation anticoagulant rodenticides (SGARs) accumulate in barn owls causing internal bleeding and death
Both species benefit from nest box programmes that provide artificial nesting sites to compensate for loss of natural cavities

Welfare Considerations

Kestrels experiencing declining vole populations from agricultural intensification face chronic food stress, reduced breeding success, and eventually starvation during harsh winters. Barn owls poisoned by SGARs die from uncontrolled internal bleeding — a welfare harm that can be prolonged over days. Road casualty barn owls suffer traumatic impact deaths, with a significant proportion surviving initial strikes to die later from internal injuries. The indirect welfare harm of agricultural intensification on field margin habitat — eliminating the rough grass vole habitat that kestrels and barn owls depend on — is not visible as animal suffering but cascades through entire food chains.

What You Can Do

Install kestrel or barn owl nest boxes in appropriate locations on farm or large garden land
Advocate for restrictions on second-generation anticoagulant rodenticide use in areas with raptors
Support the Barn Owl Trust with donations for nest box, ringing, and poison monitoring work
Choose arable and livestock food products from farms with field margin management benefiting farmland birds
