I could see that happening in certain areas. Years ago I hunted Bankhead. On the first visit I heard a pack of coyotes start howling near night fall. Just surprised me someone had not killed them out. Of course their deer numbers were low. Let the population go for a few years on a tract of land you will find out quick what wild dogs and coyotes will do. I have never seen coyotes on a tract of land like I have the last five years. Seems like on the certain large tract it is like op said, see a deer track you will see a coyote track right behind it. Never seen it like that before. At some point when the predators preferred food choice runs out something else has to take their place. If deer are all that is left deer numbers will plummet. They got to eat!
