Scientists have reported that bird flu has been found in seals for the second time in recent months at one of England's most famous colonies.
The virus was found in 15 dead seals during recent tests at Blakeney Point, Norfolk, government figures show.
Staff at the "National Avian Influenza Reference Laboratory" have carried out further tests after two grey seals tested positive at Blakeney Point in February, the BBC reported.

The results, released by the Animal and Plant Health Agency and the Department for Environment, Food and Rural Affairs, show that more than 15 of the 40 seal carcasses tested have tested positive.
Scientists said they could not be certain that bird flu was the "sole cause of death".
"A total of 40 seal carcasses were sampled from the site and 37.5 per cent (15) of these were positive. We cannot determine with certainty whether avian influenza was the sole cause of death of these wild animals and other factors may have contributed," the statement said.

The statement said the findings were reported to the World Organisation for Animal Health (OIE).
Bird flu, also known as H5N1, is a disease caused by a virus that infects birds and sometimes other animals.
The world's first case of avian flu in sheep was recently identified in Yorkshire.
Government officials have said a "small number" of human cases have been recorded in the UK since 2021.
The Department for Environment, Food and Rural Affairs says 1.78 million farmed and captive birds were culled between November and February due to the spread of the disease in the UK. | BGNES
