CarcajouPresent in all the northern regions of planet earth, the Wolverine (Gulo gulo) only rarely occurs in Eastern Canada, and only then in Labrador and Québec as well as Northern and Northwestern Ontario. 

The highest concentration of the species is found in Western Canada and Alaska.  The elusive Wolverine is something of a mystery:  difficult to observe, it is one of the least known animals in Canada.

An excellent climber

The Wolverine closely resembles a bear cub in size and appearance.nbsp; This excellent climber is also an able swimmer.  It lives far from human civilization, in the coniferous forests and on the tundra.   Its range is vast and sparsely populated.  It marks its trails with urine and musk to alert other animals to its presence. 

A variety of den sites

When the female is about to give birth, she goes looking for a shelter for her litter.  The den site often consists of tunnels in the snow, which have formed naturally around rocks and boulders.  The den may also be located under a fallen tree trunk, in an abandoned beaver house or a rocky crevice.    

The young

CarcajouAt birth, the young are covered with curly fur.  They weigh approximately 84 g.  Weaned at around two months of age, they grow quickly and are fully grown by the age of 7 months.  They start living on their own when they are 1 or 2 years old. 

Some young don’t survive their first year - they either starve to death or fall prey to predators. 

A Greedy Scavenger

The Wolverine is a poor hunter and prefers to feed on carcasses left by bears and wolves or animals caught in traps.  This dependence on others for food means it may often go hungry for long periods at a time.  It will on occasion attack an injured moose.  A solitary and ferocious creature, the Wolverine is active both during the day and at night and can cover great distances when foraging for food.

Breeding

CarcajouMating occurs between the months of May and July.  Shortly after fertilization, implantation of the blastocyst (embryo) is delayed.  Active gestation actually begins several months later and lasts from 30 to 40 days.  The baby wolverines are born between January and April. 

An average litter consists of 2 or 3 offspring.  Often, the number of babies is proportional to the amount of food available.  With the exception of the wolf, few animals prey on the Wolverine.  Predators don’t seem to relish its meat.  Its highly regarded fur, however, attracts another enemy:  man.

Bonjour ! pouvez-vous me confirmer si c'est une empreinte de Carcajou ? Si non, de quel animal s'agit-il ?? La balle sur la piste est une 30-06 de 3 1/8 '' de long ou tout près de 8 cm. ( Empreinte = 9cm X 12cm env. ) Merci de votre collaboration ! NOTE : Je n'ai qu'une photo et je ne peux la joindre, puis-je vous la faire suivre autrement ???
