Dorset puffin colony sees its first chick for first time in decades

Conservationists are celebrating a rare and hopeful discovery in Dorset, where a young puffin has been sighted emerging from its nest for the first time in 30 years, offering a boost to the region’s dwindling population.

Volunteers monitoring the Purbeck puffin colony confirmed the sighting of the fledgling, known as a “puffling,” on cliffs near the National Trust’s Dancing Ledge.

The bird was observed peeping from a deep crevice on the sheer cliff face, home to the last breeding colony of puffins on mainland England’s south coast, a group clinging precariously to survival.

This significant moment followed over 15 weeks of dedicated observation.

Volunteers meticulously tracked adult puffins through courtship, mating, gathering nesting materials, and, since late May, consistently delivering fish to their hidden nests.

The vital monitoring project is spearheaded by Dr Richard Caldow, an expert in seabird ecology, with crucial support from volunteers of the Purbeck Natural History Forum.

“With only three breeding pairs remaining, every chick matters,” Dr Caldow said.

“One puffling alone won’t save this colony, but one is a whole lot better news than none.

“We first observed fish being taken into the ledge on 31 May, with the last fish delivery recorded on 5 July.

“Based on this, we estimated the puffling to be 38 to 40 days old.

“Puffins typically fledge between 38 and 44 days after hatching, so it had reached the minimum age at which it could leave the nest.”

The puffling is expected to leave the ledge and its parents under the cover of darkness and spend the next several years alone at sea.

If it survives, it may return to Purbeck from around two years of age, although puffins do not usually breed until they are around four years old.

In April, six adult puffins were recorded at the colony.

By early June, volunteers had observed puffins carrying fish into at least two separate nesting locations on the cliff, indicating that more than one pair may have been attempting to raise chicks.

However, only one pair was regularly delivering fish to a nest site visible from the monitoring point – the location where the puffling was later seen.

While other puffins were also observed carrying fish to different parts of the ledge, these deliveries ceased after 12 June, suggesting that any chicks in those nests did not survive to fledging.

Dr Caldow said: “Seeing the puffling was a great thrill, the first puffling that’s been recorded in Purbeck for a long time.

“It tells us that Purbeck puffins can still lay fertile eggs, hatch them and, at least in some years, find enough food to rear a chick and escape the attention of predators.”

The 13 volunteers took turns to observe the nesting ledge, contributing around 150 hours of their time.

Additional puffin sightings were provided by commercial boats run by Durlston Country Park, Birds of Poole Harbour and Pierhead Watersports.

In March 2026, the National Trust renewed its efforts to understand why the puffin colony has been failing to produce chicks.

Motion-sensor cameras, powered by solar panels, were installed by high ropes experts, positioned to take images of movement within the deep fissure, where the puffins nest about two metres back from the entrance.

The cameras will be recovered after the seabird breeding season, and volunteers will then review the thousands of images taken.
