Road sign

Something new (for me) again. A road sign warning for beavers. (Toads are quite normal, although many nature lovers try to catch them before they cross the road.)
Beavers have created a pond of about 3-4000 square metres/yards where two creeks, the Bach an der Frohndelle and the Güttersbach, come together to continue as the Crumbach and end 2km further in the Gersprenz.
All rather small creeks (the German Bach means brook/stream/creek/rivulet), but of course with their own name :)
The warning is at a single track road, with not too much traffic. But better safe than sorry.
