The head of a black bear is broad and round, with two large round ears, which are quite similar in shape to Mickey Mouse. Their eyes are relatively small, but they have color vision, so that they can distinguish the difference between fruits and nuts.
Their snouts are narrow and long, light brown, and their chins are white. Although black bears' fur is not too long, there are long manes on both sides of their heads, making their big faces wider and their sense of smell more sensitive.
, even though most black bears have very long black fur.
Black bears walk on four soles and are a plantigrade animal. Their limbs are thick and powerful, and their soles are huge, especially the front soles. There are five toes with sharp claws on the soles of their feet, but their claws cannot be retracted.
In addition, like other bears, their tails are short.
There is some controversy over the subspecies of the Asian black bear. In the past, it was believed that there are four subspecies of the Asian black bear, namely Japan, Taiwan, Mongolia and the named subspecies u.t.thibetanus.
But now scientists believe that there may only be some population differences between these so-called subspecies and cannot be counted as separate subspecies. The only subspecies that can be identified today only lives in southern Pakistan.
Black bear living areas are mainly distributed in southern Asia. The distribution of this army of residents starts from the barren mountainous areas of Afghanistan, along Pakistan and northern India, Nepal, Bhutan, to Myanmar and southwestern my country, including Hainan Island and Taiwan. The northern branch is distributed in the northeast of my country, southeast Russia, and Shikoku and Honshu in Japan.
They are forest-dwelling animals, especially in mountainous areas with lush vegetation. In summer, they often move in mountains at an altitude of 3,000 meters or even higher. In winter, they will move to dense forests at lower altitudes. In order to survive, they occasionally
Will wander to the plains.
Black bears are omnivorous animals that feed mainly on plants. They like various berries, plant leaves, bamboo shoots, moss, etc. They also like to eat honey, various insects, frogs, fish and carrion. They will occasionally break in
Farms prey on domestic animals, but this behavior naturally arouses human resentment and leads to their slaughter.
Black bears travel most of the time at night and hide in tree holes or rock caves to rest during the day. In autumn, they rarely go out during the day. Although they look bulky, they are good swimmers and tree climbers. They can also rely on their backs for a long time.
Stand on its legs and use its front paws to attack opponents or obtain food.
Not all black bears hibernate throughout the winter, especially those who live in hot areas in the southern part of the subspecies. Black bears in some areas will hide in their holes to sleep throughout the winter, while others only hibernate during the harshest parts of the winter.
Hibernate.
Black bears that need to hibernate will start eating wildly at the end of summer in order to store enough fat. During hibernation, their metabolic rate will be reduced by half, and they will no longer excrete, but convert their excrement into protein (if humans also have this ability)
How good). Their heartbeat also dropped, from 40 to 70 beats per minute to 8 to 12 beats per minute. In addition, their body temperature also dropped to 3 to 7 degrees Celsius.
Black bears have their own territories, and the size of their territories varies according to food conditions. Generally speaking, the richer the food source, the smaller the territory. Therefore, the territory of black bears ranges from 6.4 to 9.7 square kilometers to 16.4 to 36.5 square kilometers.
No wait.
Black bears are far more afraid of humans than humans are afraid of them, so black bears generally stay away from humans. They usually only attack humans when they feel threatened or to protect their young. Of course, for no reason (at least from a human perspective)
) attacks on humans have also occurred.
It is understood that most of these attacks occur in late summer, around the time of mating season. It seems that animals in love may be very excited and fanatical like humans, and may view the surrounding affairs differently as a result.
Black bears are basically solitary animals. Only when mating do males and females meet and may look for food together. The mating seasons of black bears in different regions also vary. Black bears living in Russia mate from June to July every year, and their
Love babies are usually born between December and March of the following year; black bears living in Pakistan usually do not consider continuing the family line until October, and their babies are usually born around February of the following year.
The pregnancy period of a mother bear may last 6 to 7 months, and there is a phenomenon of delayed implantation of the fertilized egg, which lasts about 2 months. However, the mechanism of delayed implantation is not fully understood by humans.
Black bear mothers can give birth to 2 to 3 babies at a time. Compared with other types of mammals, newborn black bear babies are pitifully small, weighing only about 200 to 300 grams. This is because black bear mothers no longer eat during pregnancy.
, but breaks down the protein in the body into glucose to provide nutrients for the baby in the belly. Due to insufficient nutrient absorption in the mother's body, black bear babies are very small after birth.
However, the mother bear's breast milk is extremely rich in fat and nutrients, which is enough to replenish the parts they previously lost. Because of this, the mother bear does not need to breastfeed her children as frequently as other carnivores. The baby bears can only open their eyes one week after birth.
Eyes, weaning takes at least 3 months. Children usually live with their mothers for 2 to 3 years before they start out on their own, and become sexually mature at 3 to 4 years old.
Since mother bears generally give birth to babies every 2 to 3 years, some mother bears may live with children of different ages at the same time.
Black bears in the wild, if they are not killed by humans or other natural enemies, or caught alive for bile, have a maximum lifespan of about 25 years. The maximum lifespan in captivity is 33 years. If it is in a cruel and cruel bear farm
, their life span is much shorter, and they are tortured by pain every moment of their lives...
Before the Koreans “invented” live bear bile extraction, bear bile could only be obtained by killing wild black bears. According to the relevant database of the Institute of Zoology, Chinese Academy of Sciences, the wild population of black bears in my country is estimated to reach 12,000 to 18,000, with the highest estimate Only 20,000 head.
The export of bear bile to Japan from 1979 to 1984 required the killing of 47,000 black bears, not including the domestic market.
In the 1980s, after the Koreans invented the "live bear bile harvesting" technique, this "technology" became enthusiastically sought after in a short period of time, especially in my country, the main distribution country of black bears. For a time, a large number of wild black bears, especially young ones, were The cubs were captured by humans (I am afraid that the mother bear must be killed to obtain the cubs). Many of these unfortunate animals died from infection during drainage surgery or improper feeding, while those who were lucky enough to survive were forced to suffer all kinds of torture while alive. , and gradually exhausted his life in pain, until he finally died tragically...
Since black bears are not difficult to breed, the same tragic experience keeps repeating itself in the offspring of these unfortunate animals. In other words, bear cubs born in bear farms are destined to suffer mental and physical problems from the very beginning.
To spend a short life in double pain.
American black bears are large in size with stubby limbs. Their body length is about 120 to 200cm, and male bears may be much larger than female bears. There are many kinds of body colors of American black bears. The American black bears in the northeast are darker in color, mostly black;
Those living in the northwest are lighter in color, with fur colors ranging from brown, light brown, and gold; the black bears living in the mid-coast of British Columbia, Canada, even have milky white individuals, known as "spirit bears"; the American black bears in Alaska have blue
Because of their gray body hair, they are also known as "Glacier Bears".
American black bears sometimes have white chest spots on their chests. Their snouts are long and wide, and their fur is slightly lighter. Their ears are quite small, with thick, round hair, and they grow on the lower part of the head, close to the sides.
Each paw of the American black bear has five sharp claws that cannot be retracted. These sharp claws are very helpful in tearing food, climbing and digging. Of course, if anyone is swept by them with their front paws, it will be enough.
The force of their front paws is enough to kill an adult deer. The American black bear's sense of smell is extremely sensitive. In comparison, their vision and hearing are much inferior.
The American black bear is currently divided into 16 subspecies due to its diverse coat colors and body shapes. The most unique among these subspecies is the white black bear that lives in the Great Bear Rainforest in British Columbia, Canada - the white spirit bear. This site will introduce separately - the white spirit bear
(ursusamericanuskermodei). In addition, among the subspecies, the East Texas black bear (u.a.luteolus) was officially included in the federal endangered species protection list in 1992 due to its scarcity, with a level of "endangered"; the Florida black bear (u.a.floridanus)
It is also protected by Florida law because of its worrying population (the number is estimated to be 1,500 to 2,500).
