UK kestrel populations have declined significantly due to prey shortages, habitat loss, and road mortality, affecting individual bird welfare.
Kestrels with insufficient prey spend more time hunting, face starvation risk, and have reduced breeding success. Habitat loss has reduced rough grassland that supports field vole populations critical to kestrel welfare. Road-hunting kestrels face frequent traumatic injury risk. Restoring prey-rich grassland habitats and providing nest boxes directly improves individual kestrel welfare outcomes.
