Seven dead seals washed up in Donegal are believed to have died of natural causes - but concerns over a pattern of seal deaths nationwide remain.

As the Donegal Democrat reports, the seven grey seals - which are a protected species - were found beached along with a dead dolphin in the Rosberg area. 

A ranger with the National Parks and Wildlife Service confirmed that none of the marine animals had been shot.

But Pauline Beades of the Irish Seal Sanctuary said the find was just one in a series of reports of "strange" seal deaths around the country.

“You don’t find three, four, five animals dead on a beach," she said. "I would be very concerned that this is not a normal occurrence.”

It is not yet known if a post-mortem will be carried out in the dead seals, but members of the public are encouraged to report any similar finds as the thocine distemper virus has been responsible for seal deaths in the past.

Beades said that grey seals are now having their young, and asked the public to keep an eye out for seal pups and report anything that looks suspicious in the area.
