我睡得太久了吗?(Have I been sleeping too long?)

欢迎来到这个世界,小熊!在巢穴里度过了它生命的最初几个月后,这个轻浮的美国黑熊孩子可能会对外界感到困惑。幼熊出生于1月至2月,但它们要到4月中旬或5月初才能离开巢穴。当幼熊进入春天时,它们的体重约为2公斤,到一岁生日时会长到约36公斤。然而,黑熊的体重——成年时在45至272公斤之间——不仅取决于它们的年龄、性别和季节,还取决于它们居住地的饮食。黑熊是在弗吉尼亚州谢南多阿国家公园发现的唯一的熊,这为今天的图像提供了背景。

Welcome to the world, bear cub! After spending the first months of its life inside the den, this frizzy American black bear child may be puzzled by the outside world. The cubs are born between January and February, but they don't leave their den until about mid-April or the beginning of May. When the young bears emerge into spring, they weigh around 2 kilograms and grow to about 36 kilograms by their first birthday. The weight of black bears—ranging between 45 and 272 kilograms in the case of adults—however, not only depends on their age, sex and the season but is also based on the diet available in their habitation. Black bears are the only bears found in Shenandoah National Park in Virginia, which provides the setting for today's image.
