Very well said in all posts Sbruce. The part about coyotes being opportunistic is of particular truth. coyotes mostly feed on the smaller stuff , but with the populations of coyotes skyrocketing in the east it is mostly because of the availability of deer that can be easily caught by a couple coyotes, which yields a lot of food for the effort. This in turn breeds bigger and stronger dogs over the years. I lived for my first twenty yrs in AL, and never saw a coyote. You can hardly be out at night now without hearing their howls I hear.
with that said, yes coyotes AFFECT the deer herds, but not necessarily negatively. Most states in the east have way to many deer for the herd to stay healthy, but give it a few more yrs, and I am sure that in certain areas it is already affecting the herds in a negative way. We need to keep the coyote population in check by killing as many as we can. With the fur trade all but dead and gone, it is up to us hunters. AJ
