The fostering of Blaze and Brooke is only the second time in the history of the program that pups born in professional care were placed with an established wild pack.

BROOKFIELD, Ill. — A litter of five Mexican gray wolves were born at the Brookfield Zoo in April, and two of them have been released in the wild.

This is the second litter born to Zana, 4, and Flint, 6. Currently, three of the puppies are in a den being nurtured by their pack at the zoo’s Regenstein Wolf Woods habitat. The other two, named Blaze and Brooke, were placed in the Arizona-based Elk Horn Pack of wild wolves, which will foster them with its own litter.

In pup fostering, very young pups are moved from one litter to another litter of similar age so that the receiving pack raises the pups as their own.

The technique, which has proven to be successful in this species, as well as in other wildlife, shows promise to improve the genetic diversity of the wild wolf population.

Mexican gray wolves are the rarest subspecies of gray wolves in North America.

There he and his sister, Brooke (identified as F1472), will be fostered along with the pack’s own litter of newborn pups. The program is a multi-agency collaboration between the U.S. Fish & Wildlife Service, the Association of Zoos and Aquariums, the Arizona Game and Fish Department, the White Mountain Apache Tribe, the USDA Forest Service, and the USDA Animal and Plant Health Inspection Service—Wildlife Services, as well as private organizations.
