One of the only animals that can kill a healthy porcupine,this tells us something, fishers are part of the weasel family,One of the largest weaseals. In NH there is many of them in alpine area's,Fishers are great tree climbers, spend most of there time in tree's, Fishers are also very elusive, only come out during low light levels, main stay is squirrels and anything with fur that is small enough to kill, very ferocious animal, they like to growl allot when they are on the hunt, Fishers will come to a preditor call as well. fishers are know to have a a very high pitch yell, when they are clamming there soundings, sounds like a young kid screaming like she's being killed, weirdest sound I have ever heard, stands the hair on your neck, I would not kill fisher, if there is a small amount of them were you hunt, also check your hunting manual, there is seasons on them, seems to run with the fox seasons, due to mating and bearing children the season is closed at that time.I enjoy watching them. A squirrel don't have much chance ageist the fisher. I have had them come to my bait sights,once they think its there site, Fishers are known to urinate all over the place, rank smell:) Keeps away others as well. Aim small hit small. RAMbo.
