I doubt very much there is any coy-wolf inbreeding going on. What's more likely is the much larger north-eastern coyote has expanded it's territory, or rather, reclaimed much of it, moving more westerly and south. They remain in a loose pack-like society during their first year or so from birth, which gives the appearance of them being in a pack, when really it's just a den of adolencent pups. If you have a few dens around it seems like there is a large pack.
Nathan, Nathan,
"I doubt very much there is any coy-wolf inbreeding going on."
Who are we to believe? You, or that d*mn lyin' DNA?
While I hope you are correct that there is no unauthorized breeding experimentation going on...
I disagree on your theories of pups as a pack rather than adults..
Packs of adults have been seen raiding farms...a friend of mine had full grown coyotes in his barn caught pulling the fetus out of a birthing dairy cow..
Once upon a time it was pups in packs...not any more... they have gotten smarter and hunt cooperatively now.
