I have seen a family at a badger-watch organised by my local badger group We assembled in the car-park, were told a little about badgers and were briefed about how to behave (no perfume or aftershave, keep quiet and don't leap around) and then taken to see a couple of setts. We sat down a few yards from one of them, the leader sprinkled peanuts around, we got our binoculars and cameras ready then sat still and silent for an hour waiting.
When they finally appeared they were magic. Father first, who wolfed down most of the peanuts before mother and two youngsters came out, and a couple of other relations joined them. The whiffled around looking for peanuts and eating them, did some more searching and then one by one set off along a path to quarter the rest of the woods.
Worth the stiff joints and the wait.
