The scimitar-horned oryx, an animal once hunted to extinction in the wild, is continuing a return to its native North Africa, thanks to a reintroduction program now in its second release phase.

This week, a group of 23 of the antelopes will be released to a nature preserve in the African nation of Chad, New Scientist reports. It's the second such batch of re-introductees, with 25 oryx having been released successfully to the preserve in August 2016.

The scimitar-horned oryx was hunted nearly wiped out by hunters seeking its distinctive horns. Habitat loss and persistent drought conditions also contributed to its near demise.

However, the animal never completely disappeared, thanks to worldwide zoo breeding programs. The August 2016 group of oryx were delivered from Abu Dhabi to the Ouadi Rimé-Ouadi Achim Game Reserve in Chad, which is also the settling site for the new group of 23 animals.

When the first transplanted oryx arrived in Chad in 2016, it was the first time in three decades that the species had been in the country. The creatures were outfitted with GPS collars to keep an eye on their movements and allow scientists to get an idea how they were behaving, as they acclimated to their new home. Here's some Smithsonian footage of one of them being released:
