Disappearing desert denizens
This sturdy antelope is highly adapted to desert living, rarely needing to drink water. Formerly, the population covered the entire Sahara, but four-wheel drive access to the desert nearly eradicated the species. Now fewer than 500 addax exist in scattered herds in the wild.

Fossil Rim is home to the largest breeding herd of addax in the world, comprising 34 males and 50 females. Dozens of calves have been born, many of which still live here. We also conduct geriatric research as the herd ages. You'll find the addax herd in the main pasture, generally hanging out along the scenic drive route. A few elderly animals reside in the game preserve.

How they behave
The addax is highly motivated by food. We give them pelleted feed once a day, supplemented by hay and constant grazing. They get along with most of the other species, except at feeding time. Addax have no fear of humans and can be dangerous. The mothers are extremely protective of their calves, and they will attack readily if they think the calf is in danger.
