The Guardian, and The Indepdent report seabird carcasses discovered along Northumberland, North Yorkshire and Scottish shores, with many more found emaciated.
The UK Centre for Ecology and Hydrology (CEH), which is investigating the cause of the deaths, said the majority of the birds were guillemots. Puffins and kittiwakes have also been affected, but on a smaller scale than guillemots and razorbills.
