The largest flock of Spoonbills seen in Britain has been recorded on Brownsea Island, Dorset Wildlife Trust has said.
The charity said 47 of the birds have been seen on the lagoon of the 500-acre (200-hectare) island.
Chris Thain, reserve manager said: "We are absolutely delighted to see so many spoonbills. It's a unique sight."
The charity hopes the water birds, which have RSPB amber status as birds of conservation concern, will start breeding on the island.
Paul Morton from the Birds of Poole Harbour charity said: "For 50 years Poole Harbour has only ever had two or three spoonbills, but this last decade has seen numbers grow."
The flock is thought to have arrived on the island from Holland or Belgium.
