Avocet Welfare on UK Coastal Lagoons

The avocet, the RSPB's emblem, has recovered from extinction in the UK through wetland management, with welfare depending on undisturbed access to shallow, saline coastal lagoons for feeding and nesting.

Key Facts

Avocets returned to breed in the UK in 1947 after being absent for over 100 years
The UK breeding population now exceeds 2,000 pairs, primarily in East Anglia, Kent, and Wales
They feed by sweeping their upturned bill through shallow water to catch invertebrates
Avocets nest in loose colonies on bare islands or margins within managed lagoon systems
Their recovery is directly attributable to active management of RSPB reserves providing suitable habitat

Welfare Considerations

Avocet welfare depends on the management of the specialised lagoon habitats they require for breeding and wintering. Flooding levels, salinity, and substrate management all affect the availability of the invertebrate prey they depend on. Disturbance of colonial nest sites by predators including foxes causes mass nest abandonment and total breeding failure in some years. Protective management including predator control and maintaining appropriate water levels through the breeding season directly protects individual bird welfare and population stability. Climate change-driven sea level rise threatens the coastal lagoon habitats that support UK avocet populations.

What You Can Do

Support RSPB reserves and Wildlife Trust wetlands that manage habitat for avocets
Advocate for continued funding of agri-environment schemes that maintain coastal wetland habitats
Report avocet nesting attempts in new locations to local wildlife trusts and RSPB
Engage with coastal management planning to ensure sea level rise adaptation considers avocet habitat
