After many years of speculation Missouri's Department of Conservation finally confirmed a couple of years ago that Missouri does indeed have a population of wild Mountain Lions. Missouri has had way too many sightings, a few killed illegally by hunters pursuing other game, and even at least one that was struck by a car on a major highway. About a mile as the crow flies from one of my deer hunting stands a Conservation Agent videoed a large Cougar on a deer kill. The population is small and scattered, but they are here to stay. Hunting Mountain Lion here is not permitted.
We also have a growing wild/feral hog population with open hunting. They are fairly scattered, wild as all get out, and tough to hunt. I see hog sign often while hunting, just haven't ran into one yet. I have a couple of friends that have killed a few, big, burly, rangy critters (the hogs, not the friends /ubbthreads/images/graemlins/smile.gif). The hogs stay in the absolute thickest cover during the day and snow is very helpful to track them.
Missouri also has a steadily growing population of Black Bears. Bears aren't as unusual as a few years ago, one was killed this week by a resident not far from here because it attacked his dog. Guy shot it in the head with a .22 rifle! 400 pounder! That'll certainly do it but isn't my ideal of a bear defense gun. A non-resident turkey hunter killed one last year that wouldn't leave his camp one night. Our bear population is estimated to be as high as maybe 900 statewide and growing. Bears are protected just like Mountain Lions. In fact, Missouri has what is called a "permissive code" which means that if it's not permitted in the wildlife code, then it can't be legally done. Thus shooting an odd critter that one wanders into while afield, is illegal. We're getting a lot of armidillos and they can be destructive to gardens, ect... can't shoot one of the armored possums because it isn't allowed in the code book.
There was even a tagged Timber Wolf from Wisconsin killed in northern Missouri a couple of years ago. There was a Moose that wandered around and got friendly with a farmers cows several years ago. And finally a deer hunter here killed an Elk quite awhile back! I guess a fellow needs to keep his eyes open cause ya just never know what you're going to run into.
