RE: Question about droppings..........................
It sounds like bear to me, but like ABM said a trail cam would tell ya for sure.
Or like than said mud or Sand around the area will give you a nice view of a print.
One other way to know for sure is to put out some doughnuts and cover them with some logs that only a bear could move and that would be a sure way of narrowing it down.
I can't help to think it has to be a bear if it was a goat you would be able to see hoof prints. a bear(black bear) walks lightly and doesn't leave much for prints except in the sand and mud.
