Arctic foxes become sexually mature during their first year of life (10 months), but in Svalbard most of the females do not reproduce until they are 3 years old and both sexes have lower survival rates compared with other arctic fox populations. The loud contact calls made by both sexes, particularly in the winter, include a blood-chilling ‘scream’ that has unsettled many an urban resident. The Arctic fox is not extinct and is not in any danger of extinction except for a couple of small populations in northern Europe. Red foxes are twice the size of Arctic foxes and not only compete for prey, but can take their dens by killing or chasing them away. The fox - one of the most amazing animals there is! However, this species is threatened by hunting and land development. One in Russia has been reduced to around 90 animals because of a mange caused by ear ticks introduced by dogs. Foxes communicate with each other using a wide range of calls, facial expressions and body postures, as well as scent markings. The species that call the refuge home have been protected from the risks of unsustainable development for decades, but in 2017 Congress approved opening the coastal plain of the Arctic Refuge to allow for oil and gas drilling. Often called the "polar wolf" or "white wolf," Arctic wolves inhabit the Arctic regions of North America and Greenland. While you may be able to befriend an arctic fox if you live in the Arctic, the creatures are unwelcome in the Southern Hemisphere because they would upset the ecology.

The last 300 wolves left in the mainland US lived in the woods of upper Michigan and Minnesota, just making due by running at the sight of people. In the wake of being secured by the Endangered Species Act in 1974, the wolves population began to rebound. The Arctic National Wildlife Refuge is located in one of the largest remaining natural areas on the planet: Alaska. Thanks to its isolation, the Arctic wolf is not threatened by hunting and habitat destruction in the same way as its southern relatives. Climate change is extending the range of red foxes - the treeline is moving further north as the tundra retreats - so they're increasingly crossing paths with their tundra dwelling relatives, Arctic foxes. The Arctic Fox is not extinct - it is common. Two arctic fox populations are endangered, however. The Arctic fox is not endangered world wide and it is estimated that there are several thousand arctic foxes left in the wild. Twelve adult and eight pup vocalisations have been identified and 28 groups of sounds described.
