Both males and females possess permanent horns. Newborn calves are able to run with the herd immediately after birth. Įast African oryx in the Awash National Park, EthiopiaĪll oryx species prefer near-desert conditions and can survive without water for long periods. In New Mexico, predators like coyotes and mountain lions are not effective at controlling numbers, allowing the oryx to reproduce without restriction. Lions and other natural predators cull the population in Africa, with only 10% of calves reaching one year of age. This area also lacks a way to control the population. They are especially adapted to desert life and can go a long time without drinking water. Here, they feed on desert grasses, yucca, buffalo gourds, and mesquite bean pods. In Africa, they eat grasses, forbs, and melons. The success of the oryx in New Mexico is due in part to the abundance of food. Today, numbers have been held around the 2,000 mark through managed hunting efforts. At one time, numbers of Oryx in New Mexico were estimated to be around 6,000 (original release numbers were less than 100). However, the animals proved to be extremely opportunistic, and quickly spread into the San Andres Mountains to the north and west of Tularosa Basin. Researchers believed that the population would never grow beyond 500 to 600 and would remain within the Tularosa Basin. The gemsbok released onto the range quickly began to reproduce. The first atomic bomb was test detonated at Trinity Site near the northern boundary of the range. White Sands Missile Range, located between the cities of Albuquerque, NM and El Paso, TX, is a 3,200 square mile US Army facility which also hosts White Sands National Park. Between 19, 93 oryx were released onto White Sands Missile Range. Gemsbok were introduced in New Mexico by the Department of Game and Fish in the late 1960’s and early 1970’s as an experiment in offering a unique hunting opportunity to New Mexico residents. The East African oryx is an endangered species, whereas the gemsbok is not. In the past, both were considered subspecies of the gemsbok. The gemsbok is monotypic and the East African oryx has two subspecies the common beisa oryx ( O. The East African oryx ( Oryx beisa) inhabits eastern Africa and the closely related gemsbok ( Oryx gazella) inhabits southern Africa. Several thousand are held in captivity around the world. Unconfirmed surviving populations have been reported in central Niger and Chad, and a semiwild population currently inhabiting a fenced nature reserve in Tunisia is being expanded for reintroduction to the wild in that country. The scimitar oryx, also called the scimitar-horned oryx ( Oryx dammah), of North Africa, is now listed as possibly extinct in the wild. In 2011, the IUCN downgraded its threat category from extinct in the wild to vulnerable, the first species to have changed back in this way. As of 2011, the total wild population is over 1,000, and 6,000–7,000 are being held in captivity. Additional populations have been reintroduced in Qatar, Bahrain, Israel, Jordan, and Saudi Arabia. One of the largest populations of Arabian oryxes exists on Sir Bani Yas Island in the United Arab Emirates. It was reintroduced in 1982 in Oman, but poaching has reduced its numbers there. The Arabian oryx ( Oryx leucoryx, Arabic: المها), became extinct in the wild in 1972 in the Arabian Peninsula. White oryxes are known to dig holes in the sand. Herodotus mentions a type of gazelle in Libya called " orus", probably related to the verb oruttoo or orussoo, meaning "to dig". The Greek plural form is óryges, although "oryxes" has been established in English. The term "oryx" comes from the Greek word Ὂρυξ, óryx, for a type of antelope.
