Wildlife experts are no closer this evening to discovering what the mystery substance is that has caused hundreds of sea birds to wash up on the south coast.
Most of the guillemots have been found at Chesil Beach in Dorset. But one bird has been found alive as far as Worthing in West Sussex - another, discovered on the Isle of Wight.
More than 100 of the birds have been taken to an RSPCA centre in Somerset as the Environment Agency investigates where the sticky substance has come from.
Martin Dowse speaks to RSPCA Insp John Pollock, volunteer Martin Usborne and Martin Cade from Portland Bird Observatory.
