I wonder how that article relates to the south. Specifically south Texas since we also have Javelinas which are very small and an easy snack I would assume.
I've already seen coyotes feeding on them as well as on deer corn. What I have not seen, is a coyote feeding on deer. I'm not saying they don't it, I've seen it on trail cameras, just never in person.
From my years of hunting though, I've noticed deer react quickly to the presence of a coyote and take off in a heartbeat. Same thing could be said for bobcats. This only strengthens the argument that (mature) deer recognize coyotes as a huge threat. Most likely because coyotes snack on them lol.
Interesting article...
