The grizzly bear is more particular in his choice of sleeping quarters and desires better protection and concealment than the black bear. Bears sometimes come forth in fair weather for a few hours and possibly for a few days. I have known them to come out briefly in mid-winter.
With the coming of spring—anywhere between the first of March and the middle of May—the bears emerge, the males commonly two weeks or more earlier than the females. Usually they at once journey down the mountain. They eat little or nothing for the first few days. They are likely to break their fast with the tender shoots of willow, grass, and sprouting roots, or a bite of bark from a pine.
The cubs are born about mid-winter. Commonly there are three at a birth, but the number varies from one to four. At the time of birth these tiny, helpless little bears rarely weigh more than half a pound. I suppose if they were larger their mother would not be able to nourish them, on account of having to endure the hibernating fast for a month or so after their birth.
In May, when the cubs and their mother emerge from the dark den, the cubs are most cunning, and lively little balls of fur they are! By this time they are about the weight and size of a cottontail rabbit. In colour they may be black, cinnamon, or cream.
As with the grizzly, the colour has nothing to do with the species. With black bears, however, if the fur is black his claws are also black; or if brown the claws match the colour of the fur. With the grizzly the colour of claws and fur often do not match.
Few more interesting exhibitions of play are to be seen than that of cubs with their mother. Often, for an hour at a time, the mother lies in a lazy attitude and allows the cubs to romp all over her and maul her to their hearts’ content.
The mother will defend her cubs with cunning, strength, and utmost bravery. Nothing is more pathetic in the wild world than the attachment shown by the actions of the whimpering cubs over the body of their dead mother. They will struggle with utmost desperation to prevent being torn away from it.
In the majority of cases the mother appears to wean the cubs during the first autumn of their lives. The cubs then den up together that winter. In a number of cases, whenever the cubs are not weaned until the second autumn, they are certain to den up with their mother the first winter. The second winter the young den up together. Though eager for play, brother and sister cubs do not play together after the second summer. When older than two years they play alone or with other bears of the same age.
Young black bears have good tempers and are playful in captivity. But if teased or annoyed they become troublesome and even dangerous with age. If thine enemy offend thee present him with a black bear cub that has been mistreated. He is an intense, high-strung animal, and if subjected to annoyances, teasing, or occasional cruelty, becomes revengeful and vindictive. Sometimes he will even look for trouble, and once in a fight has the tenacity of a bulldog.
