Nikki Farnsworth, chair of Radcliffe-in-Trent Parish Council’s biodiversity and environment working group, said many people had been devastated by the oil spill.

“It is so lovely to have the swans back in their natural habitat,” she said.

“There has always been a nesting pair of swans [here] and I suspect there will be a lot of people popping down to check on them and enjoy seeing them back.”

Residents involved in the rescue mission have also been making visits to check on their progress, with Twine spotting signs the pair could be preparing to breed.

“What I think is the male has been gathering straw, grass and woody debris and looked like he’s trying to prepare a nest for him and his mate,” Farnsworth said.

“My hope now is for cygnets, definitely swan babies.”
