Black Bear Behavior

Black Bears Scent Marking

4-20-18 black bear biteIn the Northeast, Black Bears typically emerge from their dens in April and mate sometime between mid-May and late June. Prior to mating, Black Bears of all ages and both sexes announce their presence to other bears by rubbing their scent on marking trees (maintaining several on their territory). These “trees” often include utility poles, such as the one pictured. While most of the marking is done by mature males during the mating season, this week’s storm provided proof that scent marking actually resumes in April soon after bears come out of hibernation.

Scent marking can include a bear’s rubbing its shoulders and neck against the tree/pole as well as clawing and biting the tree. Claw marks are usually quite shallow, but incisor bites are deep enough that pieces of bark and wood are sometimes pulled out.  This photograph shows where a Black Bear stood on its hind feet and with its head sideways, grabbed the pole with its mouth open and closed its jaws, scraping a horizontal groove across the pole as its upper and lower canine teeth came together.  The height of the bite was about six feet.

Fresh bear signs indicate that it’s time to bring bird feeders in (either permanently or, at the very least, at night), in order to avoid creating “nuisance” bears,  thereby putting the bears’ lives at risk.

Tolerant Black Bear Mothers

3-28-17 black bears playing 1368

The yearlings continually challenge their mother’s patience as well as each other’s to see just how much will be tolerated. They climb on, bite, claw and test their mother in much the same manner as toddlers do their (human) mothers. At the same time, when she demands that they follow her instructions, such as climbing a tree when danger approaches, they immediately obey.
