This video segment from Nature: "Cold Warriors: Wolves and Buffalo" provides a rare glimpse into the life of a wolf pack in Wood Buffalo National Park in Northern Canada. This excerpt shows hungry pups licking at their mother's mouth to stimulate her to regurgitate her food, and young "teenage-type" wolves licking at the mouth of their father, the alpha male, to be fed the way they were when they were small. This segment first illustrates the playful nature of wolves, showing the young wolves spiritedly interacting with the pups. It explains that adult wolves return to the den for several months to feed their young and keep them alive.
