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
The Avaliks are forced to leave Silver behind so they can confront the rival pack, the wolves of Nuka River. In the fight that occurs between Kapu and the Nuka pack's alpha, Low Wind, Sweet Fur Amy and Aaka capture two Nuka wolves and bring them over to their side. The wolves, Storm Call and his sister Lichen, are the offspring of Low Wind and his mate Moon Seeker. The Avalik wolves accept them into their pack, and they return to Kangik, where they come across the strange wolf Ice Blink, and Silver′s now-lifeless body. Ice Blink offers to join the pack, but Kapu shoots her offer down, sensing something off about her. But after a while, since their pack numbers are low, Kapu reluctantly allows her to join.
