Both parents aid in bringing food to the den and in rearing the pups. Pups begin eating meat when about one month old and are fully weaned by about six weeks. They first emerge from the den when about three weeks old and begin to hunt and range away from the den at about three months.
Family units gradually break up during September and October. During midwinter, foxes lead a mostly solitary existence except when congregating at the carcasses of marine mammals, caribou, or reindeer. Arctic foxes attain sexual maturity at nine to 10 months, but many die in their first year.
In summer, arctic foxes feed primarily on small mammals, including lemmings and tundra voles. Foxes denning near rocky cliffs along the seacoast often depend heavily on nesting seabirds such as auklets, puffins, and murres. When food is plentiful, it is sometimes cached among boulders and in dens for later use.
Arctic foxes are omnivorous, and sometimes eat berries, eggs, and scavenged remains of other animals. Many foxes venture out onto the sea ice during winter to feed on remains of seals killed by polar bears. Arctic foxes may move long distances over sea ice.
A fox tagged along the coast of Russia was captured near Wainwright, Alaska a year later. In areas where lemmings and voles are the most important summer prey, numbers of foxes often rise and fall with cyclic changes of their prey. Fewer pups are successfully reared to maturity when food is scarce. There is evidence indicating that competition for food among young pups accounts for some of the heavy mortality in this age group. Arctic foxes are nomadic and travel great distances across their range, usually in a family group.
In Alaska, the arctic fox migrates seaward in fall and early winter, and will reverse movement in late winter and early spring. Studies have documented long-distance movements of several hundred kilometers. RVR At the end of a long Arctic winter, spring is starting to awaken.

Do Arctic foxes socialize? During the summer months, Arctic foxes collect a surplus of food and carry it back to their dens to bury and store. Come wintertime when prey is scarce, they will follow polar bears and wolves to scavenge the remains of their kills. Arctic foxes walk on top of the snow and use their acute hearing to listen for small creatures below. If they hear something move, they will jump up and down to break through the snow and reach with their front paws to grab the prey.
Foxes living near water take advantage of access to marine animals like fish, seals, seabirds, and marine invertebrates. THREATS: Arctic foxes are threatened by global warming, competition from the larger, northward-spreading red fox, and hunting and trapping for the fur trade.
Some populations have suffered sharp declines due to over-hunting, including those in Scandinavia, where insufficient food sources in the s and s reduced fox numbers to an estimated adults.
