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."
Shaun Ellis (wolf researcher)
After he left the Marines he contacted a Native American biologist, Levi Holt, and from their meeting he was able to spend several months living at the Wolf Education and Research Center on Nez Perce tribal lands in northern Idaho, United States as a volunteer in a project studying wolves at the foot of the Rocky Mountains. They taught him how to observe wolves, and he was able to get into a pack of wolves and live among them. He recorded wild wolf howls and gradually learned to identify individual pack members and began to realise that wolves are highly intelligent and instinctive individuals that show trust and balance within their pack's social structure.
