I agree - my evidence is anecdotal - 1000 some odd trapped coons never eaten in a trap. I do know this - when trapped, the following may get eaten in a trap: skunks, house cats; squirrels, rabbits, beavers, nutria, muskrat, feral hogs, crows, and deer - I have caught each of the above and had them eaten in the trap - but for sure not always. I cannot prove it was coyotes that did it. I have not had coyotes, coons, possums, bobcats, mink, or otters eaten in a trap. And even though I have read that coyotes will displace fox - I guess they kill them - I personally have never had a fox eaten by anything. I will also admit to having never trapped in TX - I am 40 miles away.
I am no way saying coyotes wont kill coons somewhere - but they dont here - or it is at least extremely rare. I have also read that coyotes are not important feral hog predators - but they eat the heck out of the piglets here. Coyotes will not eat a coon in my bone yard. I often put a game cam on my bone yard. Coyotes will eat a deer carcass usually the first night. Coon carcasses will rot away. I for sure understand animals have different feeding habits in different areas. I promise some of the local roaming dogs kill coons in traps. Even though I have not personally had that happen, my dog will kill a coon in a trap - or not in a trap - whenever he gets the chance.
