Brookfield Zoo's Mexican wolf pups moved to wild dens in New Mexico, Arizona
BROOKFIELD, Ill. (CBS) -- The Brookfield Zoo is helping save an endangered animal from extinction.
Six of the seven Mexican wolf pups born at the zoo in April have been placed in wild dens in New Mexico and Arizona.
It's part of a federal program that aims to re-establish the species population.
