Foxes in the Snow

Product Information

Red foxes and arctic foxes live mostly in the northern hemisphere. This puts some of them in snowy landscapes. A fox print in snow can be hard to define because snow provides many different depths and consistencies. In most cases, they are just round holes punched into the snow. If a fox can’t find food, or if the weather gets really bad, it can dig a snow den and hunker down for up to two weeks. As long as a fox is warm, it can slow down its heart rate and metabolism, which helps the animal save energy so it doesn’t have to eat as much. It’s sort of like how bears hibernate, but for a shorter period of time. Arctic foxes closer to goose colonies (located at the coasts) are less likely to migrate. Meanwhile, foxes experiencing low-density lemming populations are more likely to make sea ice trips. Residency is common in the Arctic fox population so that they can maintain their territories. Migratory foxes have a mortality rate >3 times higher than resident foxes. Nomadic behavior becomes more common as the foxes age. [45]

Snow, in my country, is some kind of…curiosity. It might snow a few days a winter, but years can go by completely snow-less as well. Arctic foxes spend hours each day roaming across the tundra during winter looking for food. This includes listening for lemmings under the snow. But hearing a lemming is only the first step in getting a meal. Arctic foxes still must catch them. Våge, D.I.; Fuglei, E.; Snipstad, K.; Beheim, J.; Landsem, V.M.; Klungland, H. (2005).

The abundance of the Arctic fox tends to fluctuate in a cycle along with the population of lemmings and voles (a 3- to 4-year cycle). [21] The populations are especially vulnerable during the years when the prey population crashes, and uncontrolled trapping has almost eradicated two subpopulations. [18] SkullDefenders is working to prevent the loss of our most vulnerable wildlife species, particularly in the Arctic, where the effects of climate change are most evident. We are advocating for no drilling on the Arctic Refuge, the protection of habitat corridors that allow wildlife to move between the refuge and Canada, and funding for on-the-ground research to better understand how warmer temperatures are affecting wildlife. Coyotes and red foxes also hunt like Arctic foxes. The noise from airplanes, vehicles and other engines likely makes it harder for these species to hear rodent footsteps under the snow. And as the human population grows, bringing noise with them as they spread across the globe and into Arctic regions, it’s reasonable to assume that Arctic foxes will also have a harder time finding food. Defenders of Wildlife’s California office works tirelessly to save San Joaquin kit fox habitat and helps to protect native grasslands in one of the fastest growing areas in the country. Defenders’ alliance with the California Cattlemen’s Association and its California Rangeland Conservation Coalition is working to restore 13 million acres of rangelands in the Central Valley—1 million acres that are vital kit fox habitat.

Arctic foxes heavily rely on hunting and catching prey to supplement their diet. However, the majority of their prey lies beneath the snow, making it difficult for them to catch it. Therefore, they have developed an inventive technique for finding and capturing their prey under the snow before killing and eating them. So here I am, me and my camera and so much whiteness that it makes me almost lose my sense of time and space.Coyotes and red foxes also hunt like arctic foxes.

Despite being adapted to the harsh conditions of the arctic tundra, the Arctic fox does not get off easy in other respects. There are still many predators that the Arctic fox needs to be aware of at all times. So what animals are likely to prey upon the Arctic fox? Arctic foxes are preyed upon by wolves, grizzly bears, golden eagles, red foxes, and polar bears, among others. It’s interesting to note that most of their predators kill arctic foxes, so they don’t compete for food with them.
