Kestrel Welfare and Urban Hunting

Kestrels are the UK's most familiar small falcon, dependent on short grassland hunting habitat and nest sites in cliffs, buildings, and trees.

Key Facts

UK kestrel populations declined by around 50% between 1970 and 2015 but show some recent recovery
They require open short grassland with abundant voles for sustained hunting success
Roadside verges managed as uncut grassland provide important kestrel foraging habitat
Kestrel boxes on buildings and trees can supplement natural nest site availability in areas where these are scarce

Welfare Considerations

Kestrel welfare is primarily determined by prey availability in their open hunting territories. As vole specialists that hover to locate prey by detecting ultraviolet urine trails, kestrels require grassland with healthy vole populations maintained through appropriate vegetation management. Road verge management that allows grass to grow sufficiently long for voles but not so tall that kestrels cannot hunt effectively provides important linear habitat corridors. Nest site availability is a secondary welfare determinant — kestrel boxes have successfully increased breeding density in areas where natural sites are scarce. The welfare of breeding kestrels during poor vole years is significantly reduced as pairs must travel further and work harder to feed growing chicks.

What You Can Do

Support road verge management approaches that maintain kestrel hunting habitat
Install kestrel boxes on buildings or trees in suitable open habitat following guidance
Report kestrel sightings and nesting attempts to local bird recording groups
Advocate for grassland management that supports vole populations as part of agri-environment schemes
