The reason that I put the bait by the fence is because I do not care about scaring the rest off. If they get caught, fine. If they don't come by and dont get caught, fine. Either way, the issue stops. I used the deer season example because it is on currently, and it does make for great bait that tneds to be readily available (i.e., FREE). So does a calf in the summer.
With all due respect, there is a hole in your logic: if 80% occurs when there are pups, do coyotes live on air the rest of the year? Should I wait until the chances of loosing more of my investment is at its peak? Or - does that mean that the other 20% of the time they are not going to continue to try to come over, I can rest up, and those tracks & turds (and the one I caught two weeks ago) just a mirage? Whether the problem occurs during the 80 or 20, it is a 100% chance that I will be severly pissed.
BTW, I have found that they DO come back. Obviously not the next night, though. Have caught two in the same week in the same spot. Once when there was nothing but bones left to chew on. Evidently, hungry is hungry no matter who you are. That seems to be the point that I learned, I guess: we spend all this time baiting traps making holes, etc. While those things definitelyhave their place, it also seems like we forgotten that real food works as well as the fake stuff - everybody's gotta eat.
If you raise livestock where large cats are you can most assuredly have this happen. Neighbors have seen them take goats over fences and found the remains in trees,creek botoms, etc. Maybe it sounds crazy, but it happens. A 4.5 foot tall fence is no big deal to a full grown mountain lion, and an extra 40 pounds -live or dead - isnt going to stop it from going over. Half of a calf isn't that big. We aren' t talking a yearling steer here. Seriously, don't take my word for it, ask around. Talk to some ranchers that have dealt with them or guides that hunt them. I put this piece of info in because I didn't see any mention by Gebhardt of his location and thought it may be food for thought - just trying to be helpful on something that stumped me at the time.
OR - are you just trying to rattle my cage?
