Woolston Eyes, a restored wetland near Warrington, has become a vital sanctuary for black-necked grebes, hosting nearly two-thirds of the UK's breeding population of the rare species. The site, previously used for depositing dredging material from the Manchester Ship Canal, has been transformed into a network of freshwater pools and reedbeds since 2021.
Black-necked grebes, characterized by their distinctive golden facial tufts and red eyes, typically number around 55 breeding pairs annually in the UK, according to the RSPB. In 2023, four pairs of the birds nested at Woolston Eyes, successfully raising 15 young. By 2025, the RSPB recorded 35 breeding pairs across the reserve, with 29 of those nesting in the newly restored wetland area.
"It is fantastic to see black-necked grebe numbers increasing at Woolston Eyes," stated RSPB ecologist Gavin Thomas. "The rapid growth in numbers shows how effective targeted conservation action can be."
Robin Horner from the RSPB described the increase as "pretty amazing," noting that over 60 birds were present on the site this spring. He highlighted the project as a significant success story where industrial activity and wildlife conservation have been harmonized.
The transformation of Woolston Eyes is managed by RSPB wardens in conjunction with the Woolston Eyes Conservation Group.
