北极狐是一种杂食性捕食者。它捕食旅鼠和其他啮齿动物,密封幼崽,鱼类,鸟类,蛋,昆虫和其他无脊椎动物。它还吃浆果,海藻和腐肉,有时跟踪北极熊吃掉它们的残骸。北极狐将多余的食物埋在缓存中以存放冬季和饲养工具包。北极狐被红狐狸,老鹰,狼,狼獾和熊捕食。世界自然保护联盟将北极狐的保护状况归类为“最不关心”。据估计,全球北极狐的数量达到数十万。然而,该物种在北欧急剧濒临灭绝,挪威,瑞典和芬兰的成虫总数不到200人。尽管几十年来一直禁止狩猎,但动物却因其珍贵的毛皮而被偷猎。俄罗斯梅迪岛的人口也濒临灭绝。北极狐面临着狩猎和气候变化带来的严峻挑战。温暖的气温使狐狸的白色冬季颜色容易被捕食者看到。特别是红狐狸威胁着北极狐。在一些地区,红狐已经成为主导,它的捕食者,灰狼,已经被捕杀到接近灭绝。疾病和猎物稀缺影响其范围某些部分的北极狐种群。

Arctic foxes are an omnivorous predator. It preys on lemmings and other rodents, sealing cubs, fish, birds, eggs, insects and other invertebrates. It also eats berries, seaweed and carrion, sometimes tracking polar bears to eat their wreckage. Arctic foxes bury excess food in the cache to store winter and feeding kits. Arctic foxes are preyed by red foxes, hawks, wolves, wolves and bears. The IUCN classifies the protection status of Arctic foxes as “the least concerned.” It is estimated that the number of global arctic foxes reaches hundreds of thousands. However, the species is rapidly extinct in Northern Europe, with fewer than 200 adults in Norway, Sweden and Finland. Although hunting has been banned for decades, animals have been poached for their precious fur. The population of the Russian island of Medici is also on the verge of extinction. Arctic foxes face serious challenges from hunting and climate change. The warm temperatures make the fox’s white winter color easy to see by predators. In particular, the red fox threatens the Arctic fox. In some areas, the red fox has become dominant, and its predator, the grey wolf, has been hunted to near extinction. Disease and prey scarcity affect Arctic fox populations in certain parts of their range.
