Monts de Gueret Animal Park
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."

The center has three packs of wolves. The Granite wolf pack has two wolves with one living there since 2007 and the other wolf has been their since 2009. and were moved into their current habitat in 2009. The River Valley Wolf pack arrived as pups in 2007 and are in a separate habitat. The two habitats are separated by the Naturalist cabin, and the two packs can see each other through the large windows of the cabin. In 2013 the Grizzly and Wolf Discovery Center added a third wolf habitat for the high country wolf pack until they were moved to a behind the scenes wolf exhibit in 2018. (Source)
