Fox Fur Ball
Photograph by Norbert Rosing
Curled up in its warm, fluffy coat, an arctic fox (Alopex lagapus)
conserves its body heat on a snowdrift in Norway's Svalbard archipelago. One
of the smallest fox species, weighing just six to eleven pounds (three to five
kilograms), arctic foxes have small ears, short muzzles, and thick fur to minimize
heat loss. |
Jump Hunter

Trotting and bounding over the frozen Churchill River near Hudson Bay, a fox
hunts for seal carcasses or other carrion. In summer a nesting colony of about
100,000 snow geese on La Pｅrouse Bay offers easier pickings. |
In the Outside World
Photograph by Norbert Rosing
Four inquisitive noses point from their den near Hudson Bay as fireweed erupts
in July. In good lemming years a female fox may give birth to as many as 20
pups, and the regional fox population booms. Males and females form mating
pairs in March or April, still in winter's grip. Females give birth about 52
days later in large, old, complex dens that may have a hundred entrances. |
Muzzle to Muzzle
Photograph by Norbert Rosing
A pair of pups play at their den site on the western end of Victoria Island
in the Canadian Arctic. They were two of only seven in this den, a low total
caused by a small lemming population in 2002, when this photo was taken. |
