ARCTIC
FOX Alopex lagopus
The
arctic fox is very small and compact which helps conserve
heat in the cold, sparse, arctic tundra regions that it lives
in. The arctic fox is now extinct in Scotland but was found
here up to the last Ice Age. Nowadays, it lives throughout
the arctic polar region, with Scandinavian animals migrating
south to the Baltic coast for the winter.
Its small ears and even the soles
of its feet are covered in thick hair which acts as
insulation. With a short, grey and white coat in summer
time and long, pure white in winter, it is almost invisible
to prey against the changing colours of the arctic tundra
landscape.In summertime, the arctic fox is active during
the day and night in the 24 hour daylight of the arctic.
In winter, they will even forage on to marine pack-ice
for food. They eat mainly small rodents, particularly
lemmings, birds’ eggs and the young of ground-nesting
birds.
During the breeding season a large
amount of prey species may be killed and buried in the ground
on the permafrost. This provides the fox with a deep-frozen
food supply for the long, dark winter months. Arctic foxes
also scavenge on the kills of other large carnivores, such
as the wolf and polar bear.They are a social species, particularly
in winter, when they live in small family based groups. The
female gives birth between April and June to a litter of 4
– 11 cubs. She will use a rock fissure or will dig extensive
shallow tunnel systems to give birth in. If prey species are
very abundant in that year, she can produce a second litter.
