Wolves are territorial animals

The Voyageurs Wolf Project video perfectly demonstrates the wolves’  seriousness and serious perception of  their territory. The video has data from the GPS collars of members of six different neighbouring wolf packs.

Wolves are strongly territorial animals. The only exceptions are some subspecies with a migratory lifestyle, such as the tundra wolf, that follows across the tremendous distances that their migrating prey cover. In general, however, the home area where the wolf family lives, hunts their prey and raises their puppies, is highly valued and it is protected fiercely from other canines (including foreign wolves, jackals, and dogs). A paw is not light-heartedly brought into the territory of other wolves - such an attempt often has fatal consequences. The border areas of their territory are diligently marked and regularly patrolled. Clarity is also added to communication by howling.  One of the many functions of it is to spell out clearly to foreign wolves: “Here is our home, you keep away.

The size of a wolf territory may vary widely, depending on the abundance of prey, number of other predators, including wolves, landscape, climate and other factors. For example, in North America, there are wolf areas as small as 260 km2, or larger such as 2600 km2. The average size of a wolf territory in Estonia is 800-1000 square kilometers.

The Voyageurs Wolf Project video contains data from the GPS collars of six different neighbouring wolf pack members from 15 April 2018 to 31 October 2018. These collars signal the location of the collar carrier every 20 minutes (72 locations per day). Such data provide valuable information on wolf motion patterns, pack area sizes and, for example, feeding. The last is done by deduction from the case that if the GPS collars show that the wolves have been in one area for a markedly long  period of time, there is a high probability of finding a  prey slain by the wolves there. This is how the researchers at VoyageursNational Park finally traced how wolves are hunting beavers in the summer - up to 8 hours of patient ambush at a beaver dam or channel.
