Maverick is a term, usually referring to cattle, for an animal that does not carry a . In the period of the United States open range, such animals were relatively common. Many cows would give birth in wild or semi-wild conditions, not be located in an annual , and their ensuing calf could thus grow to maturity without having been captured and branded for ownership. The term derived from Samuel Maverick, who, among his other claims to fame, was notorious for not branding his cattle.
Other U.S. terms for unbranded cattle include slick,hairy dick, and, in Spanish-speaking areas of the Southwest, orejano. In other parts of the world, different terms are used. In Australia and New Zealand, for example, an unbranded animal is a cleanskin.
In the code of the American Old West, such animals could be branded and claimed by any rancher able to capture and brand the animal.
In modern times, there are few true mavericks, as most cattle run on private ranches, usually calving close to a ranch where young calves are easily captured and branded prior to being turned out to grazing leases on public lands. When a mature, unbranded animal is found today, the most common practice is to make a concerted effort to locate a possible owner, and then, if the animal cannot be identified, to put it up for public auction at a Sheriff's sale, where the proceeds usually cover the cost of impounding the animal and attempting to locate an owner.
In addition to traditional hot branding, animals today may also be marked for identification by freeze branding, by tattooing, by ear tags, or by having a microchip embedded into the animal, usually in the neck. However, in the United States, a hot brand is generally the only legally recognized method of animal identification on cattle, though the law varies from state to state.
