Jet ski riders have been spotted driving into large flocks of protected seabirds resting on waters below the RSPB Bempton Cliffs nature reserve.
Some witnesses to the incident earlier this month were even concerned a few birds, currently in their breeding season, were injured by the impact.
It is not the first incident of its kind and according to Keith Clarkson, site manager at the RSPB Bempton Cliffs reserve jet skis should be banned from the waters below the cliffs during the breeding season.
“I was on the Yorkshire Belle last weekend and we were shocked to see the jet skiers just going straight through the flocks of birds without any attempt to avoid them whatsoever,” said Mr Clarkson.
He explained the sea below the cliffs where the birds nest is a critical part of their habitat as it is where they socialise, clean and even breed.
