I agree with most of what you've read & remarked about. Odd to me is why anyone/[Biologist] would call a group of coyotes a "pack" Their not wolves after all.
From what I've seen over the yrs. Their old den site area is frequented the most, any given day. Whether their useing it @ the time or not.
Most local coyotes will either be found in that area. Or within a mile or so, most days. Most often when I shoot & miss a local. That is where they run to.
Not only are territoral pairs protective of their den site area[active or not]. But are also protective of their marked territory through out.
I've watched tresspasser coyotes run away. When they seen a local coyote eyeing them from a far or moving towards them.
