Brookfield Zoo has added one new antelope to its animal population and expects to have more over the next few weeks.
The zoo said Thursday that the new addax antelope was born June 7. Three more addax females at the zoo are pregnant.
According to the zoo, the new calf is a male and was born on exhibit so visitors could witness its first moments. He weighed 19 pounds.
The zoo called the birth significant. The world's wild addax population now consists of about 300 animals. Most of them live in Niger.
Addax antelopes are adapted for desert life. They get most of their moisture from plants they eat and dew and almost never drink water.
