Called them in with mouth calls, they're predators and they're cats which makes them sneaky, bear attacks are not uncommon in our state. I think I'd be a little more worried about a mtn lion than a black bear both animals can and do kill people the one thing that stands out about a mtn lion is you probably aren't going to see it coming if the cat want's you. This ain't the first time a mtn lion has decided to kill a human and it's going to happen again. All you can do is have your head on a swivel when out in the sticks including semi rural housing areas where a mtn lion may decide to snack on livestock and pets. The drought is really getting bad here in AZ so they got to go to water and that may mean your bird feeder. Carry a weapon or other self defense item. One of our son's friend a young adult out archery elk hunting was napping by a tree not terribly far from where we live, he woke up and saw a lion about 12 -15 ft away ready to pounch on him when he swung his bow and let fly an arrow hitting the cat in the top of the head slicing a nice gouge and bleeding like a stuck hog. After he settled down and called his dad which was a few hundred yds away they called in friends with dogs to track the cat, unfortunately after losing the blood trail on hot dry ground and a couple of day's trying to find the cat they lost him. Another hunting buddy out calling coyote & fox set his electronic call up and within a couple minutes had a mtn lion come in right to the call, my buddy shot the cat and the call at the same time killing the cat and the call with one shot, the lion was sitting on a mule deer buck the cat killed a few yds away and just watched my buddy set his call and as soon as it turned on the cat went to investigate. I did something similar when hunting muley chucking small rocks down a small not very deep draw to see if anything came out then looked up and seen a big tom get up from under a juniper tree and walk off couldn't have been 50 yds. Had another one sitting right in front of us sunning himself in the middle of an old forest rd he didn't move until I tried to get out of the jeep then he hauled butt. A buddy and I chased a mtn lion into an old abandoned cowboy line shack and then I got stupid and decided to go look inside the open door without a gun in hand, boy did I get an ear full of pissed off kitty. Long time ago when the kids were young we were hunting Kaibab and on a newly cut logging road I took the jeep in and there was a Prentice log loader in the middle of the road and just as I got around the log loader there was a herd of does and then there was a mtn lion fixated stalking the deer , we jumped out and the lion took off. I don't know if you guy's notice this when mule deer hunting I always look for logging operations that are currently going on, why may you ask because when the trees are limbed in fresh piles before chipping or burning the deer will come in the get the mistletoe from the piled up branches on the ground, but where the deer are the mtn lions aren't too far away. I probably see more black bears than mtn lions only because the nature of the beast, but I guarantee you the cats are their watching you just don't see them. Another sad note locally 2 people were killed in 2 separate elk vs motor vehicles in last couple months elk didn't survive either. One of these was very close to our house.
