Sedgwick County Zoo and wildlife experts released two Mexican Wolf pups into the wild as part of an endangered species recovery plan on May 6.

Traveler, a male, and Jaunt, a female, were chosen from Sedgwick County Zoo’s family of six Mexican Wolves to be cross-fostered with a wild pack in Arizona by the U.S. Fish and Wildlife Service, said Nancy Smith, senior zoo keeper.

Cross-fostering is a process where pups from one litter are placed with another litter to be raised by the mother wolf as her own to increase population size in the wild and increase genetic diversity. The process must take place within days of both sets of pups being born, according to a news release.
