Wild Dunlin Estuary Welfare | Animal Welfare Hub

Dunlin are the UK's most numerous wintering wader, gathering in large flocks on estuaries, with welfare linked to intertidal food availability and disturbance management.

Key Facts

UK wintering dunlin populations exceed 300,000 birds, making this a globally significant winter site
They feed on invertebrates in tidal mudflats at low tide using rapid bill-probing techniques
Repeated disturbance from dogs and recreational users causes energy expenditure and starvation risk in cold weather
Key estuaries including the Wash, Solway and Thames support tens of thousands of wintering birds
Estuarine developments through land claim reduce available intertidal habitat for wintering waders

Welfare Considerations

Dunlin winter welfare depends on undisturbed access to productive tidal mudflats. Controlling recreational disturbance and protecting intertidal habitats from development are the most effective interventions.

What You Can Do

Keep dogs on leads on estuaries during winter and avoid flushing wader flocks
Record dunlin numbers at estuaries through WeBS surveys
Support campaigns against estuarine development that destroys intertidal wader habitat
