However, by 1967, the magnificent species was facing extinction south of Canada and was placed under protection by the Endangered Species Act in 1974. The answer dates as far back as the Middle Ages. The gray wolf is a complex creature with a variety of temperaments. The family structure of the gray wolf more closely resembles that of humans than any primate society. Wolves tend to be loyal, respectful, and affectionate to their family members.
Wolves learn, communicate, and amuse themselves in ways that mimic the tendencies of humans.
Wolf packs are usually composed of an alpha male and an alpha female, their offspring, and sometimes a group of non-breeding adults. Some packs are composed of as many as 36 members. Wolves begin mating when they are roughly 2-3 years old and their young, usually an average of five pups, are born around April. Pups remain in the den for about six weeks, and are cared for by the entire pack. Wolf packs usually live in very large territories.
