  • The best time of year to look for marten is in the late fall and early winter when juveniles disperse.

Behaviour

Martens are solitary, except for mating season and while a mother is raising her young. They each have an approximately 5 km2 territory where they live and hunt. They are carnivores and don't store food for winter months so they are always searching for food. American Martens have limited body-fat reserves and lose body heat rapidly. They will frequently rest to conserve energy, tunneling under the snow to a warm cavity in a hollow log or tree stump. To further conserve energy, they may even go into daily torpor, where they reduce their metabolism and body temperature and stop moving for a short period of time.

Diet

Voles, deer mice, squirrel, lemmings, shrews, birds, eggs, hare and carrion.

American Martens and people

  • Marten skins were used to make fur robes for higher-class persons. "Wealth woman," a mythical figure known to the Tagish, Tutchone and Tlingit people, wore such a garment.
  • One of the most cost-effective furbearing animals to trap. Because it is curious, the marten is also one of the easiest animals to trap. This makes it vulnerable to over-harvesting.
  • The biggest effect on marten populations is loss of habitat from large forest fires and clear-cut logging.
