The diet of Arctic foxes is mainly comprised of meat and other proteins. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds.
It also eats carrion, berries, seaweed, and insects and other small invertebrates, such as eggs of white geese.
If you take a closer look at life in the Arctic, tiny lemmings and white geese are central to the survival of the Arctic fox.
When lemmings are everywhere, it’s easy to obtain food for the pups – of which there could be up to 18 in each litter.
It is possible, then, to see many Arctic fox pups on almost every foxhole, well-nourished, content and basking in the sun.
The absence of lemmings, in turn, strongly affects the colony of white geese – as in June, goose eggs are a great nutritious alternative for the Arctic fox pups to feast on.
Any leftover goose egg treats are reserved for the future by being hidden in the frozen tundra.
When the young grow up and begin to explore the territory, they will find most of the eggs hidden by their parents, enabling higher survival rates for the new generation.
The sad reality is that the Arctic fox teens spend a lot of time looking for food, but they are often unlucky, with as many as two out of three pups destined to die from starvation.
