In June a beaver family of four animals housed in the Dyle river near the Begijnhof in the center of city of Leuven. The beaver (castor fiber) is the largest rodent in Europe and is now back in Belgium in some places. Beavers are nocturnal and generally very shy. But these beavers showed up at dusk and were not disturbed by the many people who where watching them dragging and eating branches. In early July however they were chased.
