Endangered Mexican Gray Wolves Born at Brookfield Zoo

The Chicago Zoological Society is excited to announce the birth of a litter of Mexican gray wolves, who recently emerged from a den site at Brookfield Zoo’s Regenstein Wolf Woods habitat. Born in late May to first-time mother Zana, 3, and first-time father Flint, 5, the puppies are now becoming more active and visible. Guests have a chance to view them along with their parents playing and exploring their nearly two-acre outdoor environment.

Ernesta Gray Wolf Update

The Chicago Zoological Society is saddened to report that Ernesta, a Mexican gray wolf who once resided at Brookfield Zoo, was found deceased in the Gila wilderness recovery area on January 7, 2015. Her death is still being investigated by U.S. Fish & Wildlife Service officials. Ernesta resided at the zoo from November 2010 until October 2012. She was then transferred to the U.S. Fish & Wildlife Service’s Sevilleta Wolf Management Facility at the Sevilleta National Wildlife Refuge, New Mexico, in preparation for her second release to the wild, which occurred in July 2014.
