There’s been a badger sett in West Park for as long as I can remember. As far as I know, it’s been occupied all that time, and still is. Now, an excavation has begun which seems to be making the beginnings of a new sett, in just about the opposite side of the park to the established one.
I can’t think of any other explanation for this hole. But if it is a possible new sett, there isn’t much progress being made. I’ve been back around it a coupl;e of times since I took this picture, and no fresh earth has been thrown up.
