I know it's hard to tell from this picture, but I found this pile of droppings around six inches off the ground, halfway up a tuft of molinia grass. Do mink stack their droppings in this way, or is it more likely to have been an otter? The dump has been under snow for the past three weeks, so much of the structure and detail has been lost - and no, it never actually occured to me to smell it!
