A topic like this can really get people started. I'll offer my thoughts right up front. I don't think it amounts to a hill of dung where the coyote's from. There do seem to be some minor genetic differences, particularly in regards to color and size, but beyond that, I think a coyote, is a coyote, is a coyote, and frankly I think it's silly to try and draw a line between the too. I believe the prime determining factor in how hard a coyote, or any animal for that matter, is to catch is determined primarily by population density.
Obviously, you can catch more animals when more of them are present, but it goes beyond that. As animals begin to fill their habitat, competition for the resources become keener and more aggressive. This, in my opinion, makes any
individual animal more susceptible to falling for a set. In other words, increased competition causes them to drop their guard somewhat.
A coyote is a coyote, no matter where it's from. The ease or difficulty in catching it is not, in my opinion, a matter of geography.
