A trapper I used to know swears he saw one fight a badger that was trying to defend a big pile of deer corn...
The badger lost a leg in the fight and limped off...the fisher
got the corn..
Dont know if he also ate the badgers leg...but that would be typical of them.
We had one (or more?) here in mass. that was spooking people in the suburbs.
My mother saw one - she thought it was a sick dog. We all thought she was nuts, until it was identified.
Glad they don't grow too large...
