Addax Born at Brookfield Zoo
Birth of Endangered Antelope Helps Raise Awareness of Species’ Plight in the Wild
 
Brookfield, Ill.—It is not exactly a stampede, but the sound of little hooves can be heard at Brookfield Zoo with the birth of an addax antelope on June 7and severalmore are expected in the coming weeks.

The male calf, which weighed 19 pounds, was born on exhibit so many zoo guests were able to witness its first moments of life. The birth is a significant one for the species as it is near the brink of extinction in the Sahara deserts of Africa. Nearly 200 addax live in 19 accredited North American zoos, with about 300 individuals living in the wild, so every addax birth is crucial to saving these antelope.

The pairing of Sara, 4, the mom, and Winston, 11, the sire was based on a breeding recommendation from the Association of Zoos and Aquariums’ Addax Species Survival Plan (SSP). An SSP is a cooperative population management and conservation program for the species in North American zoos. The program manages the breeding of addax in zoos to maintain a healthy, self-sustaining population that is both genetically diverse and demographically stable. This calf will play a vital role in its species’ survival. Brookfield Zoo has exhibited addax antelope since 1935 and has contributed 141 calves to the North American population since 1941, when it had the first calf born in the United States.

Once abundant, addax are now found mostly in Niger, according to researchers, with roughly two-thirds of the remaining wild population living there.Only a handful of free-roaming addax are found in countries like Chad, Mauritania, and possibly Mali.However, there is hope for the species thanks to an international collaborative effort. The Chicago Zoological Society, which manages Brookfield Zoo, is one of more than 40 organizations worldwide that have provided support for the reintroduction of zoo-born addax into fenced reserves in Tunisia.

Addax are the most desert-adapted antelope, with wide hooves that are extra large and spread out, perfect for staying on top of loose sand. Their legs are shorter than those of most antelope, giving them a low center of gravity and keeping them steady—even when the sand shifts under foot. They get nearly all the moisture they need from the sap of vegetation and from dew, going almost their entire lives without drinking water at all. When vegetation is not available, they live off the water stored in their body fat. Addax have some of the most impressive horns of all antelope. In older individuals, they can spiral almost three turns and extend nearly three feet. Addax are one of a group of species called “horse-like antelope,” which are unusual in that the females have horns as long as those of the males. The calves are born with “horn buds” which begin to grow into horns after the first few weeks.

Other members of the addax herd at Brookfield Zoo are females Martha, 13; Mali, 5; and Mona, 15—all expecting calves this summer. They can all be seen on exhibit along the zoo’s 31st Street animal habitats.

The Chicago Zoological Society, which manages Brookfield Zoo, inspires conservation leadership by connecting people with wildlife and nature. The Chicago Zoological Society is a private nonprofit organization that operates Brookfield Zoo on land owned by the Forest Preserve District of Cook County. Open every day of the year, the zoo is located off First Avenue between the Stevenson (I-55) and Eisenhower (I-290) expressways and is also accessible via the Tri-State Tollway (I-294),Metra commuter line, CTA, and PACE bus service.
