Apache, a 7-year-old old male Mexican wolf recently arrived at Brookfield Zoo to be paired with 2-year-old Ela. The two will be the new breeding pair at the zoo and it is hoped they'll successfully breed this winter season and produce a litter of puppies in the spring. They can be seen at the zoo’s Regenstein Wolf Woods habitat. More at CZS.org/AlphaWolves | Brookfield Zoo Chicago
