Foxes, Weasels,
Lemmings and Hares These smaller animals are relatively
abundant throughout Nunavut, and can be seen near most communities. In 1919, red foxes
crossed Hudson Strait from Quebec to Baffin Island, and reached the Queen Elizabeth
Islands by 1962. The red fox (tiriganniarjuaq) goes through phases of colors,
including silver, black, brown and red. On average, they have litters of four to eight
pups. The arctic fox (tiriganiaq) is white during winter, but changes to largely
dark brown in summer. Arctic foxes usually bear only four to six young. As with the red
fox, litter size increases significantly in years when lemmings are numerous.
Foxes travel extensively in search of food they can be found
almost anywhere. Although it's hard to predict if you will see any, foxes are curious and
may approach your camp. However, a fox that approaches too closely and appears overly
friendly could have rabies; play it safe and scare it away. The young become independent
in September so you might see them in their quest for food. Foxes eat lemmings, hares,
ptarmigan, bird eggs, decaying flesh from carcasses, and garbage.
The least weasel, or ermine (tiriaq), is probably the most
commonly seen mammalian predator of the arctic tundra. The weasel lives wherever it can
form a den to raise young and store prey in times of abundance. They den among rock piles,
loose earth and both Thule and modern-day houses. When lemmings are abundant, so are
weasels. You may see them flashing behind a building, across a street or even between your
feet. In summer, these long, sleek animals are brown, but in winter they don an all-white
coat, ending in a long, black-tipped tail. Although they depend mainly on lemmings, these
small but fierce predators will tackle prey up to the size of arctic hares. They are
usually no problem to larger animals, although they will defend themselves if cornered.
On a warm spring day, have you caught a glimpse of a dark fur ball
skittering across the snow that magically vanishes? It was probably a lemming (avinngaq)
out for its first above-snow adventure in many months. For smaller predators like the
weasel, fox and snowy owl, lemmings are the life-blood of the arctic tundra. Snowy owls
often produce young only when lemmings are in abundance. Lemmings are mainly seen in
summer but are active throughout the winter, living in nests made of grass and burrowing
through snowy tunnels along the ground. Lemming numbers usually go through a four-year
cycle, but some peaks may bring greater abundance than others and some areas may
experience peaks sooner than elsewhere. Nunavut is home to two species: the brown (kajuqtaq)
and collared (amirta or qilangmiutaq) lemming. The brown lemming prefers
wetter areas, while the collared lemming is usually seen in rocky terrain. The collared
lemming turns white in winter, and is the only one to occupy the High Arctic islands.
The arctic hare (ukaliq) is widely distributed across
Nunavut. They live among rocks on rough hillsides and mountains, where they have ready
shelter from foxes, gyrfalcons and other predators. Hares eat grasses, sedges, willows and
other plants. Across most of their range, they are seen in small family units, but on the
Queen Elizabeth Islands you may encounter herds of 100 or more. From a distance, these
groups look like white clouds flowing across the summer tundra. In southern parts of their
range, they may moult to grey or brown in summer.
