Antelope   Habitat
Pronghorn antelope are native to the prairies of North America. At one time they numbered in the millions and were found on the open plains from the Mississippi River to the Rocky Mountains and from Mexico to central Canada. With the European settlement of the plains, the population was reduced nearly to extinction. In Arizona, antelope are found primarily in the northern plains. They also inhabit high elevation meadows between forested areas, semi-desert grasslands, and scattered herds are found in the grasslands of southeastern Arizona. The endangered Sonoran pronghorn occurs in Mexico and southwestern Arizona.

Life History
The name pronghorn comes from the pronged or sharply pointed horn of the male antelope. The females' horns are smaller and more slender. Antelope have true horns in that the horny tissue is composed of fused hairs which form over a bone core. Horns reach their maximum size during the summer and the sheaths are shed annually, usually in the fall.

Antelope have exceptional eyesight, often compared to high-powered binoculars, and are one of the fastest animals, being able to run in excess of 60 miles-per-hour. Despite their speed, antelope are reluctant to jump over objects, preferring to go under fences.

A conspicuous characteristic of the antelope is the white rump patch. When alarmed, the hair stands erect and appears as a white flash that can be seen for miles. Tan is the dominant body color, with sharply contrasting white markings on the head and neck. The top of the buck's nose is dark and there is usually a triangular black patch below the ear. The doe does not have this black cheek patch. A short mane is present along the top of the neck. Shedding is continuous with the individual hairs being loosely attached making antelope hides worthless as rugs. Since the hairs are hollow and can be erected at will, pronghorns are able to adjust to temperature changes.

Adult male antelope weigh 90 to 120 lbs. Females are about 20 lbs. lighter. Antelope are primarily browsers, especially on sagebrush, with grass being only a minor food source. Wild antelope usually reach ages of 6 to 8 years.

Hunt History
Once second only to deer as a game animal, Arizona's antelope were first given a closed season in 1893. The response must have been less than satisfactory, however, as the season was completely closed in 1905. By 1922, the state's antelope population was estimated to be less than 1,000 animals.

Then, for reasons that still are not fully understood, pronghorn antelope began to make a comeback. Aided by a closed season, government predator control programs, and the abandonment of numerous homesteads, pronghorn numbers steadily increased until fears were expressed that some northern Arizona populations were in danger of exceeding their food supply. Accordingly, a limited hunt of 400 buck permits was authorized for northern Arizona in 1941.

After a closed season from 1944 to 1948, antelope hunting in Arizona recommenced in 1949. Hunts were liberalized gradually, until 1954 when 1,600 permits were issued and 1,146 bucks were taken. Despite the issuance of a number of antlerless antelope permits between 1961 and 1975, this level of harvest has never again been equaled. Annual harvests since 1990 have varied between 500 and 700 bucks, with archers taking a proportionally larger percent of the harvest in recent years. Plagued by encroaching subdivisions, increasing highway construction, and other land-use changes, maintaining even the present number of antelope is dependent on citizen involvement and an aggressive translocation program. Approximately 10 percent of the antelope harvest is in areas having reintroduced herds.


Antelope are gregarious. They are found in mixed herds most of the year; except in the spring when the bucks are alone or in small groups. In the fall, bucks collect harems up to 15-20 does, which they then defend from other bucks. Antelope breed in August and September and the young are born in May and June. The gestation period for the antelope is the longest for big-game animals in the United States. About eight months after mating, one or two fawns are born. The young are not spotted like the fawns of the deer family, but instead have markings similar to the adults. The fawns remain hidden, with the doe feeding them several times a day until they are strong enough to travel with the adults.

Antelope Management Plans and Information

Pronghorn Antelope Management Plan, December 2011

Plan goal: Develop the framework for pronghorn management and issue resolution consistent with the Department’s Wildlife 2012 Strategic Plan, Wildlife Program – Game Subprogram Operational Plan, Pronghorn Management Guideline, and the Guidelines for the 2010-2011 and 2011-2012 Hunting Seasons, and Statewide Pronghorn Habitat Evaluation (Ockenfels et al. 1996).
