Well browing.204, I look at it like this, obviously different than you look at it, BUT a couple of things. When you are driving the roads at night to locate coyotes, 1) how many coyotes are at the same place during the day that they are at night? and 2) I think coyotes can recognize another coyotes voice. In other words, a bitch can recognize her dog/mate from other coyotes.
Why do you use a howler on every stand? And what type of howls do you use on every stand?

If you don't beleive coyotes get call shy/educated, why is it that it gets so much harder to call later in the season,(other than fewer pups to call)and when there are other callers working the same area that you do. They do get educated.
The great thing about calling predators is, there's no set rule. if you call long enough, you'll have coyotes break every rule, like coming in up wind of you, stopping after they get shot at two, three, four times,... not spooking when they see your movement etc.

The other thing about coyotes learning that a rifle/gun shot is danger is...in the mid-west there are guys that use pick-ups to drive through pastures and fields, and they shoot into the cover, and thecoyotes usually come out on the run. If the coyote didn't hear gun shots as danger, why would they run from it?
Also, when calling here in CO., I can often shoot a coyote and continue to call and often call in another, or two, coyote from the same stand. BUT, I have yet todo that in KS., in an area that I discribe above. I believe that in KS., the coyotes get shot at enough to know that a gun shot equals danger. SO, once I shoot one coyote on a stand, any other in coming coyote will stop and turn tail! To the coyote in KS., gun shot equals life or death and they have learned that!
