Brown Bears

A Brown Bear (Ursus arctos)

This blog frequently describes mammals which are extinct or not well known—creatures like the pseudo-legendary saola, the furtive golden mole, or the long-vanished moeritherium, however today Ferrebeekeeper is going all out and writing about one of the wild animals which people think about most frequently.

“Oh no! Humankind is thinking about us.”

The brown bear (Ursus arctos) is beloved, feared, worshipped, hunted, despised, and glorified by humankind.  These great bears are arguably the largest land predator alive today (their only rival is their near-cousin, the polar bear).  A Kodiak brown bear can weigh up to 680 kg (1500 lbs) and stand 3 meters (10 feet) tall when on two legs.  Brown bears can run (much) faster than the fastest human sprinter.  Likewise they can climb and swim better than we can.   They are literal monsters—mountains of muscle with razor sharp teeth and claws.  However, bears have become so successful and widespread not because of their astonishing physical prowess, but because of their substantial intelligence.

Ursus arctos live in India, China, the United States, Russia, and throughout Europe.  Because they live across such a broad swath of planet Earth, brown bears are divided into nearly twenty subspecies, but these various brown bears all share the same basic characteristics and traits.  Brown bears are primarily nocturnal and crepuscular, but they can hunt and forage during the day if it daylight suits their needs.  Since they are ingenious omnivores, they are capable of living in many different landscapes and habitats.  Usually solitary by nature, the bears sometimes gather together in large numbers if a suitable source of nutrients becomes available (such as a salmon run, a dump, or a meadow full of moth larva). The bears eat everything from tiny berries and nuts on up to bison and muskox.  Although the majority of bears live primarily by foraging, some families are extremely accomplished at hunting.  Brown bears pin their prey to the ground and then begin devouring the still living animal.  This ferocious style means that humans greatly fear bear attacks, even though such events are extremely rare everywhere but Russia (where all living things continuously attack all other living things anyhow).

Bears are serial monogamists: they stay together with a single partner for a few weeks and then move on romantically.  The female raises the cubs entirely on her own.  Gravid bears have the remarkable ability to keep embryos alive in a suspended unimplanted state for up to six months.  In the midst of the mother bear’s hibernation, the embryos implant themselves on the uterine wall and the cubs are born eight weeks later. Remarkably, if a bear lacks suitable body fat for nursing cubs, the embryos are reabsorbed.

Experts believe that brown bears are as intelligent as the great apes.  There is evidence of bears using tools, planning for the future, and figuring out formidable puzzles (although they are terrible at crosswords). Their high intelligence can make bears seem endearingly human—as in the case of a beer-drinking bear from Washington State.  After drinking one can of a fancy local beer and one can of mass market Busch, the bear proceeded to ignore the Busch while drinking 36 cans of the pricier local brew before passing out. There are famous bear actors with resumes more impressive than all but the most elite film stars.  In other cases, bears and people have worked together less well.  Brown bears used to live throughout the continental United States, but they were hunted to death.

The “healing hands” of this bear were held to be especially helpful in treating joint problems.” (from http://arctolatry.tumblr.com)

Humans and bears have a love-hate relationship: although bears have been driven out of many places where they once lived, the practice of bear-worship was so widespread among circumpolar and ancient people that there is even a word for it: “arctolatry”.  Bear worship is well documented among the Sami, the Ainu, the Haida, and the Finns.  In pre-Roman times, bears were worshiped by the Gauls and the British.  Artemis has a she-bear form and is closely associated with Ursus Major and Ursus Minor.  Yet bear worship stretches back beyond ancient times into true prehistory.  Cult items discovered in Europe suggest that bears were worshiped in the Paleolithic and were probably of religious significance to Neanderthals as well as Homo Sapiens.  Indeed, some archaeologists posit that the first European deities took the form of bears.
