I'm no biologist but I do know how to research and read what biologists say regarding coyote predation rates on whitetail deer. The general rule of thumb is a minimum avg of 1-2 fawns killed per coyote per year. Most of which takes place within the first six weeks of a fawn's birth. Everytime I hear a large pack of coyotes howling at night, which is a regular experience here in south Alabama these days, I'm reminded of just how many of our deer their killing off each year.
