In late September I was west of Casper Wyoming about 25 miles and watched a coyote test out a group of mule deer does and see if it could get the fawn. This was a large fawn but still the coyote spent about five minutes circling the does testing the situation out. The does and fawn were very afraid of he coyote. Here is a very interesting article about predator prey relationships.

I am not a fan of hound hunters having mostly hunted solitary all my life but for out of control populations it may be necessary.
