Sorry, no pictures but hopefully I can describe clearly enough. Beside my barn is a hardcore track. It's grassed over with a thin layer of soil and gravel (think it was laid over 30 years ago). Anyway, along about 20 yards of it something has dug numerous little pits in a fairly narrow strip, as if they were looking for grubs or roots. Suspect it might be a badger but could also be fox, squirrel or even a bird (crow)?
