American black bears

  American black bears appear in a variety of colors despite their name. In the eastern part, most of these bears have shiny black fur, but in the west they grow brown, red, or even yellow coats. To the north, the black bear is actually gray or white in color. Even in the same litter, both brown and black furred bears may be born.
  Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell.
  Like all bears, the black bear is timid and rarely dangerous, but if attacked, most can climb trees or cover ground at great speed. When angry or frightened, they are formidable enemies.
  Black bears feed on leaves, roots, fruit, insects, fish, and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike squirrels and many other woodland animals, bears do not actually sleep through the winter months. Although the bear does not eat during the winter months, sustaining itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute.
  Most black bears live alone, except during the mating season. They prefer to live in caves. Baby black bears are born in January or February after a gestation period of six to nine months, and they stay with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild, and even longer in some nature reserves.

美國黑熊
  盡管有著美國黑熊的名字美國黑熊卻以各種顏色出現。在東部,大部分的熊都有閃亮的黑色皮毛,但在西方,它們長著棕色,紅色,甚至黃色的外套。在北方,黑熊的顏色實際上是灰色的或白色的。即使在同樣的垃圾中,棕熊和黑毛熊也可能出生。
  黑熊是所有美國熊中最小的,從五到六英尺的長度,體重從三百五十磅。他們的眼睛和耳朵很小,他們的視力和聽覺不如它們的嗅覺那樣好。
  像所有的熊一樣,黑熊膽小,很少危險,但如果受到攻擊,大多數人都可以以極快的速度爬樹或覆蓋地面。當生氣或害怕時,他們是可怕的敵人。  黑熊以樹葉,根,水果,昆蟲,魚類甚至更大的動物為食。熊的最有趣的特性之一,包括黑熊,是他們的冬眠。與松鼠和許多其他的林地動物不同,熊實際上并不在冬天的幾個月內睡覺。雖然熊在冬季不吃東西,但它本身從脂肪中維持,但它的體溫幾乎是正常的,它每分鐘呼吸有規律的4或5次。
  除了交配季節,大多數黑熊都是獨自生活的他們喜歡住在洞穴里。寶寶黑熊是在一到兩個月的懷孕期間出生的,六到九個月的懷孕期間,他們和母親一起生長,直到完全長大或約一年半。黑熊在野外能活長達30年,甚至在某些自然保護區能活得更長。
