<P> Very little is known about the movement of the Arctic wolves, mainly due to climate . The only time at which the wolf migrates is during the wintertime when there is complete darkness for 24 hours . This makes Arctic wolf movement hard to research . About 2,250 km (1,400 mi) south of the High Arctic, a wolf movement study took place in the wintertime in complete darkness, when the temperature was as low as − 53 ° C (− 63 ° F). The researchers found that wolves prey mainly on the muskoxen . There is no available information of the wolves' movements where the muskoxen were . </P> <P> The Arctic wolf is of the least concern when it comes to being endangered but it does face threats of endangerment . In 1997, there was a decline in the Arctic wolf population and its prey, muskoxen (Ovibos moschatus) and Arctic hares (Lepus arcticus). This was due to harmful weather conditions during the summers for four years . The recovery of the Arctic wolf population came when summer weather conditions returned to normal . </P> <P> In the wild, Arctic wolves' primarily prey on muskoxen and Arctic hares . They have also been found to prey on lemmings, reindeers, Arctic foxes, birds and beetles . It has been also found that Arctic wolves scavenge through garbage . This sort of food source will not always be found in the Arctic wolves diet because of regional and seasonal availability . Sometimes there is debate whether the muskox or the Arctic hare is the primary prey for the hare - wolf - muskox predator - prey system . Studies provide evidence that the muskoxen are indeed their primary prey because wolf presence and reproduction seems to be higher when muskox is more available than higher hare availability . More supporting evidence suggests that muskoxen provide long - term viability and other ungulates do not appear in wolves diet . Evidence suggesting that Arctic wolves depend more on hares claims that the mature wolf population paralleled the increase of hares rather than muskoxen availability . The study goes on to say that degree of reliance between the two sources of food is uncertain and that the amount of consumption between the two species depends on the season and year . Debate continues when seasonal and diet of young wolves is discussed . According to one study, muskox calves serve as a primary food source because the needs of pups are greater but another study suggests that "when hares were much more plentiful (Mech, 2000), wolves commonly fed them to their pups during summer ." These differences may be attributed to location as well . Polar bears are rarely encountered by wolves, though there are two records of wolf packs killing polar bear cubs . </P>
