This video shows the European beaver (Castor fiber) eating bark.
Filmed in the beginning of the evening, when beavers get active.
From Belgian daily Het Volk:
The beaver is back in [the Belgian province] Limburg.
It is estimated that there are at least six beaver families now.
A success story, as the animal had been extinct for decades, until it came back a few years ago from the Netherlands.
Belgian Limburg seems to be fit for the animal to live.
