Montana is home to the Rocky Mountain Elk Foundation and has a historic big game hunting tradition. There are fall bow and general hunting seasons for elk, pronghorn antelope, whitetail deer and mule deer. A random draw grants a limited number of permits for moose, mountain goats and bighorn sheep. There is a spring hunting season for black bear and in most years, limited hunting of bison that leave Yellowstone National Park is allowed. Current law allows both hunting and trapping of a specific number of wolves and mountain lions. Trapping of assorted fur bearing animals is allowed in certain seasons and many opportunities exist for migratory waterfowl and upland bird hunting.
