Wolves live, travel and hunt in packs of 4-7 animals on average. Packs include the mother and father wolves, called the alphas, their pups and several other subordinate or young animals. The alpha female and male are the pack leaders that track and hunt prey, choose den sites and establish the pack's territory. Wolves develop close relationships and strong social bonds. They often demonstrate deep affection for their family and may even sacrifice themselves to protect the family unit.
Wolves have a complex communication system ranging from barks and whines to growls and howls. While they don't howl at the moon, they do howl more when it's lighter at night, whichoccurs more often when the moon is full.
