Mama bear has it tough! In the Russian taiga, a big burly grizzly boar has nothing to fear from tigers. But Mamma Bear must be ever alert for tigers. She never knows when some stealthy tiger might be creeping up on her. Even more stressful, she must be keenly aware of tigers and other predators when she has cubs to look after. Now, try to imagine Mamma Bear living in Pleistocene N. America where there are grey wolves, dire wolves, cougars, giant cheetahs, jaguars, scimitar cats, saber-toothed cats, giant lions, and a bear the size of a bison.

Even the female polar bear encounters running hyenas in the past and with nowhere to hide there is no doubt the yellowish white mother bear will defend her cubs to her death.

ourcommunitynow.com/news-national/video-mama-grizzly-bear-charges-at-car-after-driver-slows-down-to-look-at-cubs VIDEO: Mama Grizzly Bear Charges at Car After Driver Slows Down to Look at Cubs. Don't mess with Mama Bear! Calvin Barrett, of Colorado, was driving through Montana's Beartooth Highway when he spotted a mother grizzly and her three young cubs. In video footage captured by Barrett, you can see the cubs attempting to climb over a snowbank, but what happens next should be a lesson to everyone who comes across any wildlife—especially mother bears. The mama bear's protective instincts kick in and she charges at Barrett's car when he gets a little too close for comfort.

Bears are slow breeding compared to deer and most animals. Although ungulates give birth to one calf at the time, these calves are able to run several hours after they are born whereas bear cubs are vulnerable for the first few months and stay with their mothers for the first few years meaning a mother bear will not mate again until their cubs have become independent.

From the book "Notes of an East Siberian hunter"
It is very rare for a female bear to give birth to young after she had left her den; this would happen only if March was very warm, and the bears left their dens before the normal time, or when something had driven the mother bear out of her den. In such a case the mother makes a soft nest, a logovo, or gaino, as Siberians call it, in a remote and hard-to-access place; when the cubs are born, she will not leave the nest until they open their eyes and become strong enough to walk.
In the beginning, the mother feeds her cubs with milk out of her teats, of which she has two, near her front legs. If she gives birth to cubs in the den, she remains there until they open their eyes, and then she leads them to a specially prepared nest. This is why male bears leave their dens sooner than females. Anyway, the mother bear does not take her cubs with her for a long time, but keeps them in the nest. When they grow up and become stronger, she leads them everywhere. Therefore, people see female bears with cubs from May onwards. A female bear is smaller and more agile than a male bear and her character is milder, but when she is with her cubs, she will attack anything. She knows no fear and doesn't care about her own life. At any sign of danger, the cubs climb a tree, and the older cubs, born in the previous summer, follows them. The mother moves forward against anything that might have frightened them. It is rare for cubs to run away, with the mother following them, without her paying attention to what they had encountered.

Cub survival rate is estimated based from the period when bears emerge from dens in the spring to when the last cub observation happens prior families denning up for winter. Cub survival was sixty-four percent from 1983 to 2001, and decreased to fifty-five percent from 2002 to 2011. Yearling survival during the same time periods decreased from eighty-two percent to fifty-four percent. _Julie Argyle

When the chart reads, "Dominant species Wolf", the momma bear is concerned for her cubs. She can't be everywhere. While she is fighting or chasing one wolf, another wolf might be killing a bear cub. The smart choice is for her to put distance between herself with her cubs from the wolf pack. A lone adult brown she-bear will resist more often that a bear with cubs. She will often defend a carcass, depending on the number of pack members.
