In America, fox hunting is also called 'fox chasing,' as the purpose is not to actually kill the animal but to enjoy the thrill of the chase. A hunt may go without a kill for several years, despite chasing two or more foxes in a single day's hunting. As a rule, foxes are not pursued once they have 'gone to ground.' American fox hunters undertake stewardship of the land, and endeavor to maintain fox populations and habitats as much as possible.
In 2007, the Masters of Foxhounds Association of North America listed 171 registered packs in the U.S. and Canada. This number does not include the non-registered (also known as 'farmer' or 'outlaw') packs. In some arid parts of the Western United States, where foxes in general are more difficult to locate, hunts track coyotes and, in some cases, bobcats.
