On Wednesday, July 6th 2011 a 57- year old man was mauled to death by a female grizzly bear on a trail at Yellowstone National Park. Unfortunately the hiker (and his wife, who survived) encountered the bear sow while she was with her two cubs. Without exception mother bears are violently protective against any perceived threat to their offspring. An encounter with a mama bear is easily one of the most hazardous scenarios for a hiker in North America.


The recent tragedy in Yellowstone reminds us to respect the beasts we visit when we spend time in the outdoors. Of all the wildlife a wise hiker is bound to respect, bears rank first and foremost. Intelligent, curious, common, powerful and fierce, bears are among the most magnificent- and the most dangerous – of all creatures to be found on the trail.

There are 3 major types of bear to be found in North America- Black Bear, Brown Bear, and Polar Bear (The ever-famous Grizzly Bear is now considered a sub-division of Brown Bear). All should be treated with respect, and given a wide berth indeed.

Black Bear Ursas americanus

The most common- and because of this perhaps the most dangerous - of all bear species in North America is the black bear. Black bears are the smallest of North America’s bears – with adult males weighing in at fewer than 550 lbs, usually. From nose to toes, the length is about six and half feet. They’re incredibly strong for their size, and can casually flip over boulders that weigh over 250 lbs. In addition, black bears are surprisingly graceful runners, able to hit speeds of 25-30 mph. No human could ever hope to outrun a black bear (or any other type of bear) under any circumstances.

Despite the name, “black” bears come in several shades, including black, brown, blonde, and cinnamon. Albino black bears are rare, but they exist.

Black bears are so common that International Union for the Conservation of Nature classifies them as “Least Concern” – their population is high enough that they’re in no perceived danger of extinction.

This is good news for the black bears and for their ecosystem, which relies on the bears to keep the insect population in check. Black bears are omnivorous, and thus place plants, animals and bugs on their menu. They love to feast on young trees and other plants, saplings and shoots being a favorite. Black bears are also fine connoisseurs of nuts, berries and fruits, causing much consternation amongst the gray squirrel and chipmunk populations, who are powerless to defend their winter hoards against kleptomaniac black bears. Possessing a sweet tooth, black bears enjoy raiding beehives as well, considering the stings of the indignant bees a small price to pay for the golden honey goodness inside. Black bears will occasionally augment their diets with a some good old fashioned prey, sometimes a moose calf or faun, and very often fish in a local river or creek.

Black bears are found throughout Canada, the Pacific Northwest, the entire Rocky Mountain range, all throughout New England, and up and down Appalachia and the Great Smokey Mountains. They’ve even found places to live in northern Mexico, and in parts of Arizona and New Mexico. Always adaptive, black bears can tolerate most climates, and can be found almost anywhere there’s a food source, and timber for a habitat. This adaptability and large population means that these bears have the highest occurrence of human vs. bear encounters.
