Conservation efforts for the Mexican gray wolf are moving forward.
The Fish and Wildlife Service says eight pups have been successfully fostered with surrogates in the wild.
The pups were born at an endangered wolf center in Missouri and are part of a technique known as cross-fostering, which introduces pups to a wild female to see if she will care for them.
Six of the wolf pups were taken in by packs in New Mexico while the other two were taken to Arizona.
The goal is to improve the genetic diversity of the wild wolf population.
