Stopover sites where migratory birds rest and refuel during long-distance migrations are critical welfare and conservation chores, with habitat quality directly affecting individual survival and condition.
Individual migratory birds experience genuine welfare threats during migration: exhaustion from long-distance flight, vulnerability to weather events while fatigued, and mortality or injury from windows and communication towers. The welfare of stopover habitat is inseparable from individual welfare - birds arriving at degraded or food-poor stopover sites face energy depletion that compromises immune function, breeding success, and survival. Fatigue-related vulnerability to predation and collision is greatest when birds have insufficient refueling opportunities. Protecting and restoring stopover habitats is one of the highest-leverage welfare and conservation interventions available for migratory birds.
