Wild Brent Goose Wintering Welfare

Dark-bellied brent geese migrate from Siberia to winter in UK estuaries and saltmarshes. Understanding their wintering welfare needs supports conservation.

Key Facts

UK wintering brent geese number approximately 100,000 birds
They feed on eel grass in estuaries and have adapted to feed on arable fields
Population success depends on breeding conditions in Siberia, which vary annually
Disturbance on estuaries causes energy-costly flushing of large flocks
Climate change is affecting eel grass availability in traditional wintering estuaries

Welfare Considerations

Brent geese repeatedly disturbed from feeding areas on estuaries incur significant energy costs. Birds in poor body condition following long migration are most vulnerable. Maintaining undisturbed intertidal feeding areas on key estuaries is essential to the welfare of these long-distance migrants.

What You Can Do
