Two endangered Mexican gray wolves and three of their pups have moved from the Phoenix Zoo to the El Paso Zoo in a bid to bolster the number of predators.
The Arizona Republic reports that three other pups stayed in Phoenix and are now adjusting to an emptier den and establishing a new hierarchy.
Phoenix Zoo officials say that while it doesn’t have a breeding pair anymore, it plans to change the enclosure to make it appealing to a breeding female wolf.
The other wolves were transferred under a cooperative breeding program that aims to help the Mexican gray wolf survive.
