Coyote, jacks, a few others, prairie dogs etc, no license required by anyone.
We don't have a 'hunting license' like some states do. For big game etc. you just get a tag for that species. I think it's kind of odd some places make you get a license just to hunt and then another for deer, another for elk. Seems like the general hunting license is just money they want. Well, I KNOW that's what it is, but seems odd since I've never had to go through it.
