The wolf pack howls on average for 85 seconds. It is usually started by a single wolf, after which other wolves may join in. The pack leader, the alpha wolf, usually uses a lower-pitched howl and howls more frequently than wolves standing on the lower rungs of the pack's hierarchy. Although some functions of the howling are still unknown by scientists, they believe that wolves may howl to scare off other wolf packs from their territory and to gather their own pack, as wolves possess perfect hearing and their howling can be heard for up to in the forest and in open space. Researchers have found a relationship between the number of times a wolf howls and the strength of their relationship with other pack members. According to Friederike Range, co-director of the University of Vienna's Wolf Science Center, "the strength of the relationship between wolves predicted how many times a wolf howled."
Julie's Wolf Pack
With the caribou now returned to Kangik, Kapu and his pack—known as the Avaliks—plan to hunt and regain their strength. Kapu, son of Amaroq, has been alpha since his father′s death in the first book, and has managed to hold his status since. When the story starts, the pack consists of himself, his mate Aaka, his brother and beta Zing, his and Aaka′s daughter Sweet Fur Amy (referred to as Amy in the previous book), Kapu and Zing′s mother Silver, and her mate Raw Bones, the former alpha of the Colville River. Raw Bones continuously tries to usurp Kapu′s position as alpha male, but Kapu beats him back every time, occasionally with the help of Zing, Aaka, and more recently, Sweet Fur Amy.
