Woolston Eyes wetland hosts 64% of UK's
A restored Cheshire wetland now supports 64% of Britain's breeding population of the rare black-necked grebe, with 35 pairs recorded in 2025.
A restored wetland in Cheshire has become Britain's premier site for the rare black-necked grebe. According to a report from The Guardian, Woolston Eyes now hosts 64% of the UK's breeding population of the species.
Since 2021, the Royal Society for the Protection of Birds (RSPB) and the Woolston Eyes Conservation Group have managed the site. They have transformed a former dumping ground for canal dredgings into a mosaic of freshwater habitats.
Habitat Restoration
The work revived dried-out wetland areas on a settlement lagoon. Conservationists created nesting islands to attract black-headed gulls. Black-necked grebes nest beside these gulls for protection from predators. The restored wetlands also provide a rich new source of invertebrate food for the birds.
Black-necked grebes are glossy black and chestnut-coloured. They have tufts of gold feathers behind their ruby-red eyes.
Population Growth
The restoration has driven a rapid increase in the grebe population. The figures show a clear success story.
| Year | Pairs Breeding on Restored Area | Total Pairs Recorded | Young Successfully Raised |
|---|---|---|---|
| 2023 | 4 | Not specified | 15 |
| 2025 | 29 | 35 | Not specified |
By 2025, 35 pairs were recorded at the site. Of these, 29 nested on the newly restored wetland area. This total represents 64% of the average number of breeding pairs recorded annually across the UK.
RSPB ecologist Gavin Thomas commented on the results. "It is fantastic to see black-necked grebe numbers increasing at Woolston Eyes thanks to the hard work of staff, volunteers and partners to create prime habitat for this rare and attractive species," he said. Thomas noted the rapid growth demonstrates how effective targeted conservation can be.
Site Management and Importance
Woolston Eyes is a Site of Special Scientific Interest (SSSI) in Warrington. It relies entirely on rainfall to remain wet. Water can be moved between areas so they can be dried out, refreshed, and reflooded. This rotation is crucial for the black-necked grebe, which will abandon wetlands that become too "mature."
The site is also a stronghold for other rare species. These include the willow tit, pochard, and grasshopper warbler.
Thomas emphasized the broader importance of such wetlands. "Black-necked grebes are just a handful of the millions of breeding, wintering and migratory birds that rely on the UK’s internationally important wetlands," he stated. He argued that restoring and managing wetlands is vital for species recovery. However, he stressed the need to scale up this work and deliver far more sites like Woolston throughout the UK. For now, the sight of increasing grebe numbers makes the hard work worthwhile.
