Some fun interaction between these two species yesterday morning. The coyote was hunting in a field when the deer approached. The buck stood atop a nearby hill for quite a while, trying to decide if it would be safe to pass.
Eventually he figured it was worth the risk and walked by but never took his eyes off the wily canine who, of course, kept close watch on the buck.
Certainly the deer doesn’t have much to fear from a lone coyote but, judging from the rough condition of its antlers, its rut has not been going well so I can’t blame it for being so wary. 😉
