Confidence: It's likely to be this, but I can't be certain.
Notes: I can't say definitively that this isnt badger dung but its highly unlikely due to the location. Otter spraint is less likey again based on the structure of the dropping. Being found on remote moorland and consisting of what it does its unlikely to belong to a dog. I think this is the dung of a fox that has scavanged bird remains recently or actually caught a live bird/ eaten domestic fowl. Large quills are clear to see within the dropping.
