An otter has survived a “perilous” three-mile sea crossing to the Farne Islands for the first time, the National Trust has said.
The animal, more commonly found in rivers, has swum from the coast of Northumberland despite rough seas.
Head warden David Steel said he was stunned to find 60 yards of otter tracks on Brownsman Island, which is famed for its bird colonies.
The mammal has not yet been sighted, but it is thought to be still there.
