Pine marten spotted in Kielder forest for first time in 90 years

Fearsome predator was extinct in England but Scottish relatives have crossed the border and set up home in Northumberland

The pine marten, a fearsome but diminutive predator driven to extinction in England, has returned to the country's largest forest for the first time since 1926.

Stills and video from a camera trap have recorded a mature pine marten devouring peanut butter put out for red squirrels at a secret location in Kielder forest, Northumberland.
