The mystery substance found on hundreds of seabirds washed up on the south coast is a “mixture of refined mineral oils”, says the Environment Agency.
Wildlife experts have warned many more birds could be affected by the waxy substance. Hundreds of birds were found on beaches from Sussex to Cornwall on Thursday. Environment Minister Richard Benyon said: “Every effort is being made to identify the cause of this problem. I’d like to thank everyone involved in helping the seabirds affected and it’s thanks to their efforts that many have been cleaned up and now have a chance of survival.”
The total rescue count so far is 162 alive and rescued, but 200 are dead, including a juvenile puffin, a fulmar and 3 razorbills. It is thought the substance may have been dumped into the English Channel by a ship. Most birds have been found in Dorset but others are appearing in Sussex, Hampshire, Devon and Cornwall.
