This is a pine marten video from Scotland.
Translated from RTV Drenthe in The Netherlands:
A researcher of the Marterwerkgroep found two young pine martens in a hollow tree.
Never before pine martens had been found in the Dwingelderveld.
Only the related stone martens are regularly seen in the area.
However, pine martens had been spotted before in the border region between Drenthe and Friesland provinces.
