A nature reserve in New Orleans, Louisiana, will help more than 20 species of rare and endangered animals. Scimitar-horned oryx are a type of desert antelope. They once lived in northern Africa but are now considered to be extinct in the wild. They live in herds of 20 to 40 animals that are led by a single male.

Masai giraffes are the largest subspecies of giraffe and the tallest land mammal on Earth. Males can reach heights of 18 feet, and females typically grow to be 14 feet tall. These giraffes can be identified by the oak-leaf pattern on their coat. Baby giraffes, like the one shown here, can walk when they are about one hour old.

Blue cranes are found in the great grasslands of southern Africa. Because they eat crops to survive during the winter, people often poison them to protect their plantings. Even though the bird is protected by law, their species is still at risk.

The saddle-billed stork uses its bright beak to hunt for food in shallow water. Its long legs keep the bird dry while it wades in search of prey. Saddle-bills usually have the same mate every year and work together to raise their fuzzy white chicks.

The roan antelope has a distinct black-and-white mask. It lives in herds of up to 20 females and young, usually accompanied by one male. Mothers protect their calves from hyenas, leopards and wild dogs by hiding them in tall grass and staying nearby.
