I have come across several black small poos in our wood recently and am wondering what may have deposited them. Might it be a Pine Marten? That would be good. I have some Peanut Butter I will have to start smearing it around.

 

Here is a link to an article by the Gloucestershire wildlife trust about Marten poo.
