A restored wetland in Cheshire is now home to almost two-thirds of the UK's breeding black-necked grebes, one of the country's rarest breeding birds.

Woolston Eyes, near Warrington, was previously a dumping ground for dredging from the Manchester Ship Canal. It is now the site of the country's largest colony of the species.

Black-necked grebes are known for their distinctive golden facial tufts and average about 55 breeding pairs in the UK each year, according to the RSPB, external.
