I have a little experience trapping coyotes back east. Before I headed east I poked fun at a few guys telling me how hard it was to call coyotes in Virginia. I thought ahhh, I'll show em, they don't know what they're doing. Well, I certainly had to eat some crow and was quickly humbled. Not impossible, but not an easy task, and nothing like calling out west. After a few times, I said enough of that. Spoiled I guess. Also, the first coyote I trapped out there and the next five on the same ranch was quite an experience. Had a calf complaint, put out some sets and when I showed up to check, I remember looking across the field at this coyote in my trap. I was with the land owner and I said something like , what the crap is that. It was a whopper. Weighed 49 pounds and all of those five except one weighed well into the mid to upper 40's. The smallest was 39 pounds.
There are certainly some what I would call "normal" coyotes, but there are some very different coyotes out there too. Not to mention it is not uncommon to catch a red or a black. I heard one howl behind the place I was staying one night in the Appalachia. Was the lowest guttural howl I'd ever heard, again I thought, whoa, never heard an old dog coyote sound like that before. I caught that howler a few weeks later. I didn't weigh him, but he was very big. I've been lucky enough to trap and hunt coyotes in six states, all but Virginia have been west of the Missouri River. So...to me, a portion of the coyotes I dealt with in Virginia were a different animal. Coyote/wolf hybrid? I don't know, but I do know there is something very different out there. I don't mean that in a spooky way, just saying its a different coyote.
