Wild Shelduck Estuarine Welfare | Animal Welfare Hub

Shelduck are large estuarine ducks with distinctive moult migration to the Wadden Sea - their welfare reflects estuary health.

Key Facts

Shelduck are one of the largest UK ducks breeding in burrows along coastal marshes and estuaries
Most UK shelduck undertake a moult migration to the Wadden Sea in Germany each summer
Estuarine habitats including intertidal mudflats provide the invertebrate food for winter welfare
Sea level rise and coastal squeeze are reducing intertidal habitat available to shelduck
Disturbance by boats and jet skis on estuaries forces birds from resting and feeding areas
UK shelduck populations are largely stable but locally affected by habitat degradation

Welfare Considerations

Shelduck welfare during the breeding season requires undisturbed burrow nest sites and access to nearby intertidal feeding habitat. During winter, energy balance on estuaries is maintained by access to abundant invertebrate prey in undisturbed intertidal areas. Coastal recreation management that protects feeding areas during low tide is the most direct welfare intervention.
