Wild Bird: Whimbrel Migration Welfare

Whimbrels are wading birds that pass through the UK in spring and autumn during their remarkable migrations between African and Arctic breeding grounds.

Key Facts

Whimbrels breed in northern Scandinavia and Arctic Russia, wintering in West Africa
Spring passage through the UK peaks in May, with birds stopping to refuel on estuaries
Shetland holds a small UK breeding population of around 300 pairs
The UK spring count provides an index of population trends across the entire flyway
Whimbrels feed on intertidal invertebrates during stopover, building fat reserves for onward migration

Welfare Considerations

Whimbrel welfare during migration depends on the quality of UK stopover sites, which must provide sufficient food to fuel onward flight to breeding grounds. Disturbance of feeding whimbrels on estuaries wastes critical energy at a time when fat deposition is essential. Protecting key stopover estuaries from human disturbance and maintaining invertebrate food supply is the priority welfare intervention.

What You Can Do

Maintain respectful distance from feeding whimbrels on estuaries during May
Support estuarine nature reserve management that protects invertebrate food supply
Advocate for protection of key whimbrel stopover sites from development
