The last remaining colony of puffins on the Dorset coast is in danger being lost altogether, conservationists have warned.

Home to about 40 pairs of puffins around 80 years ago, the colony near Dancing Ledge in Purbeck has dwindled to just three pairs in recent times.

Although these birds have engaged in courtship behaviour, mating, and nest building in each of the last three years, and even feeding chicks in 2023, they have not raised any fledges in recent years.
