I'm all for killin Coyotes (haven't had the opportunity with a bow), but is it true that by strict regulation of their reproduction they almost always return close to carrying capacity (where they are well established)?

I read somewhere that they are nearly impossible to get rid of because the alpha male keeps the pack at a certain level, if some start to die they do some heavy reproducing. The people studying them said their ability regulate their pack size was fascinating, and that a kill here and there would do absolutely nothing to their long term population.

FWIW, we killed our first Coyote and hog on our property this year and we ain't thrilled about it.
