It's a great image whatever kind of animal it is. Really sharp and a graet contrast with the grass.

Yes, this is a coyote. Perhaps the same coyote I shot (with a camera) a few weeks ago at YNP?

Please, wolves are not bad. They're beautiful, intelligent survivors - feeding and caring for their families like the rest of us. IMHO.
Nice capture of this beautiful animal.

You'll notice the "big" preceding the "bad" - the "big bad wolf" is a fictional reference to Little Red Riding Hood and other tales from folklore. So I'm not saying the wolves are big and bad! I probably should capitalize it and make it "Big Bad Wolf" to make that clearer.
