Great Crested Grebe Welfare on Lakes and Reservoirs

The great crested grebe underwent one of the UK's earliest conservation successes after near-extinction due to feather hunting, and today welfare depends on undisturbed nesting on productive freshwater bodies.

Key Facts

Great crested grebes were hunted almost to extinction in the 19th century for their feathers
The species became the focus of some of the first bird protection legislation in the UK
Today approximately 4,000-5,000 pairs breed in the UK, primarily on lakes and reservoirs
Their spectacular courtship displays, including the weed dance, are among the most elaborate of any bird
Chicks are carried on the backs of adults for warmth and protection in the early weeks

Welfare Considerations

Individual great crested grebes face welfare risks from disturbance at nesting sites by water sports, anglers, and boat traffic. Nest inundation from water level changes in reservoir management can destroy clutches and cause breeding failure. Entanglement in fishing line and predation on nests by increasing populations of invasive signal crayfish are additional threats. Maintaining buffer zones around known nesting sites and sensitively managing water levels during the breeding season directly protects individual welfare and breeding success.

What You Can Do

Maintain a respectful distance from great crested grebe nesting sites when on or near water
Support local wildlife trust designation of water bodies with reserve status protecting nesting grebes
Advocate for water level management plans that consider bird nesting schedules on reservoirs
Dispose of fishing line and tackle responsibly to prevent entanglement injuries
