Starling murmurations are a spectacular wildlife phenomenon, but the welfare of roosting starlings depends on adequate roost site availability, food access, and protection from disturbance.
Starling welfare across their annual cycle is challenged at multiple stages. In farmland, invertebrate loss from pesticide use reduces chick food availability, causing breeding failure. Roost site loss from reedbed drainage and building management reduces winter shelter. Murmurations - the spectacular aerial displays - are anti-predator behaviour reflecting the welfare pressure from aerial predators. Individual starlings separated from the murmuration face acute predation risk. Cold winters with inadequate food resources before migration cause mortality. Garden feeding with protein-rich foods including mealworms directly supports starling welfare through winter.
