American black bears
[size=3][color=#29384e][font=Times New Roman]American black bears appear in a variety of colors despite their name. In the eastern part of their range[/font][font=宋体]，[/font][font=Times New Roman] most of these brown[/font][font=宋体]，[/font][font=Times New Roman] red[/font][font=宋体]，[/font][font=Times New Roman] or even yellow coats. To the north[/font][font=宋体]，[/font][font=Times New Roman] the black bear is actually gray or white in color. Even in the same litter[/font][font=宋体]，[/font][font=Times New Roman] both brown and black furred bears may be born.[/font][/color][/size][size=3][color=#29384e][font=Times New Roman] [/font][/color][/size]
[size=3][color=#29384e][font=宋体] [/font][font=Times New Roman]Black bears are the smallest of all American bears[/font][font=宋体]，[/font][font=Times New Roman] ranging in length from five to six feet[/font][font=宋体]，[/font][font=Times New Roman] 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.[/font][/color][/size]

[size=3][color=#29384e][font=宋体] [/font][font=Times New Roman]Like all bears[/font][font=宋体]，[/font][font=Times New Roman] the black bear is timid[/font][font=宋体]，[/font][font=Times New Roman] clumsy[/font][font=宋体]，[/font][font=Times New Roman] and rarely dangerous [/font][font=宋体]，[/font][font=Times New Roman] but if attacked[/font][font=宋体]，[/font][font=Times New Roman] most can climb trees and cover ground at great speeds. When angry or frightened[/font][font=宋体]，[/font][font=Times New Roman] it is a formidable enemy.[/font][/color][/size]

[size=3][color=#29384e][font=宋体] [/font][font=Times New Roman]Black bears feed on leaves[/font][font=宋体]，[/font][font=Times New Roman] herbs. Fruit[/font][font=宋体]，[/font][font=Times New Roman] berries[/font][font=宋体]，[/font][font=Times New Roman] insects[/font][font=宋体]，[/font][font=Times New Roman] fish[/font][font=宋体]，[/font][font=Times New Roman] and even larger animals. One of the most interesting characteristics of bears[/font][font=宋体]，[/font][font=Times New Roman] including the black bear[/font][font=宋体]，[/font][font=Times New Roman] is their winter sleep. Unlike squirrels[/font][font=宋体]，[/font][font=Times New Roman] woodchucks[/font][font=宋体]，[/font][font=Times New Roman] and many other woodland animals[/font][font=宋体]，[/font][font=Times New Roman] bears do not actually hibernate. Although the bear does not during the winter moths[/font][font=宋体]，[/font][font=Times New Roman] sustaining itself from body fat[/font][font=宋体]，[/font][font=Times New Roman] its temperature remains almost normal[/font][font=宋体]，[/font][font=Times New Roman] and it breathes regularly four or five times per minute.[/font][/color][/size]

[color=#29384e][font=宋体][size=10.5pt] [/size][/font][size=10.5pt]Most black bears live alone[/size][font=宋体][size=10.5pt]，[/size][/font][size=10.5pt] except during mating season. They prefer to live in caves[/size][font=宋体][size=10.5pt]，[/size][/font][size=10.5pt] hollow logs[/size][font=宋体][size=10.5pt]，[/size][/font][size=10.5pt] or dense thickets. A little of one to four cubs is born in January or February after a gestation period of six to nine months[/size][font=宋体][size=10.5pt]，[/size][/font][size=10.5pt] and they remain 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 [/size][font=宋体][size=10.5pt]，[/size][/font][size=10.5pt] and even longer in game preserves set aside for them.[/size][/color]
