Ruthie Holbrook also went for a walk along the beach and she emphasised the need to discover the cause of these deaths.

She took pictures of every bird she saw to report them all to DEFRA.

She said: "The cause or causes of these deaths needs to be determined. 

"We need to know if it is avian flu and if so what protective measures we can put in place.

"If it is toxicity then we need to know what the source is.

"If it is starvation then what has happened to their food sources?"

A DEFRA spokesperson said: "Stranded and/or dead dolphins should be reported to CSIP (Cetacean Strandings Investigation Programme).

"We recommend that the animal is not touched.

"The removal of the bodies should be arranged by the local authority and as such the wash up should be additionally reported to them."
