Endangered wolves born in Mexico Zoo

Mexico City dwellers can now visit a litter of five Mexican wolves born at the Chapultepec Zoo on April 24.

Wolf cubs are born blind and deaf, so they spend most of their first few months of life inside their den, with brief trips outside that extend as they develop. The Mexican wolf is a subspecies of gray wolf chased and hunted by men since the 1950s, nearly causing its extinction in the 1970s. Mexico City's Secretariat of the Environment has invited people to choose the name for the five cubs. Voting remains open until August 15.
