Yup, MAC's right - Fishers LOVE to eat porcupines.
I don't think anything except for a human is going to FK w/ a Fisher in New England.
I would love to throw a wolverine & a badger into a pit and see who survives (yeah - in theory I wouldn't really do it). I got my $ on the wolverine.
Badger vs fisher could be a close battle = money on the badger!
CT has had a huge increase of Fisher over the past decade. I am sure MA as well. I've never seen one out in the wild in MA, not a bobcat. I've tracked them, but never caught up to one. They are there. Never seen a black bear either up close = co-worker of mine stumbled across a den in ME one time and started walking backwards and the bear woke up and ran STRAIGHT at him (escape route). Needless to say he GTF out the way ..... LOL.
I need to get back out to the woods again - miss the solitude.
