Diet of Kit-rearing Female Martens in Northern Michigan
The American marten (Martes americana) is a small, slender-bodied, carnivorous mammal found throughout the northern portion of North America. Our study focused on the populations in the Manistee National Forest in Michigan’s Lower Peninsula and the Hiawatha National Forest in Michigan’s Upper Penins...

We sought to obtain an understanding of reproducing female marten diets in order to maintain optimal marten habitat. We observed martens behaving as generalists, consuming many types of prey. Small prey species were consumed more often, but large prey provided the majority of female marten caloric intake. Gray squirrels were especially important prey for lactating females. We documented consumption of eastern moles and the delivery of multiple prey to the den at the same time, both previously unreported for this species.
