‪行走在地球上最强大的掠食者

3
00:00:27,320 --> 00:00:29,864
‪但要登上顶峰需要的…

4
00:00:35,119 --> 00:00:36,746
‪不仅仅是蛮力

5
00:00:38,331 --> 00:00:40,166
‪凭借非凡的脑力

6
00:00:41,334 --> 00:00:44,253
‪并最大限度利用地所有机会

7
00:00:45,880 --> 00:00:49,926
‪熊统治着地球上一些
‪生存环境最残酷的土地

8
00:00:55,056 --> 00:00:58,684
‪但幼崽并不是天生就具备生存的技能

9
00:01:00,937 --> 00:01:02,438
‪它们需要被教导

10
00:01:04,857 --> 00:01:08,152
‪所以熊妈妈要做的工作就是

11
00:01:08,236 --> 00:01:09,779
‪让幼崽准备好

12
00:01:09,862 --> 00:01:11,614
‪面对这个世界

‪被冬天的冰冻笼罩着

16

‪北部的森林

17
00:01:38,975 --> 00:01:39,892
‪像是定格了一般

18
00:01:42,186 --> 00:01:43,146
‪寂静无声

19
00:01:44,897 --> 00:01:46,691
‪没有迹象表明

20
00:01:48,192 --> 00:01:50,111
‪一头巨熊

21
00:01:50,903 --> 00:01:53,447
‪藏在积雪下睡觉

‪呼吸缓慢

‪自秋天以来就没有东西吃

25
00:02:20,016 --> 00:02:21,392
‪三个月以来

26
00:02:21,976 --> 00:02:25,646
‪这头美洲黑熊一直处于冬眠状态

27
00:02:29,901 --> 00:02:31,360
‪更为神奇的是…

28
00:02:34,572 --> 00:02:36,282
‪三周前

29
00:02:36,365 --> 00:02:40,036
‪它醒来的时间刚好足够

30
00:02:40,703 --> 00:02:41,954
‪生下三只幼崽

31
00:02:48,878 --> 00:02:52,673
‪每只幼崽只有一罐汤那么重

32
00:03:00,932 --> 00:03:04,310
‪虽然它只能靠脂肪储备生存

33
00:03:05,102 --> 00:03:07,021
‪但它的宝宝不会挨饿

34
00:03:09,732 --> 00:03:11,234
‪它的乳汁非常充足

35
00:03:12,401 --> 00:03:14,362
‪以至于幼崽的体型
‪已经是原来的两倍大

36
00:03:19,408 --> 00:03:23,037
‪同样的故事正在北美洲各地上演

37
00:03:25,539 --> 00:03:28,709
‪超过50万头正在冬眠的黑熊

38
00:03:29,669 --> 00:03:30,753
‪要么藏在地下

39
00:03:32,964 --> 00:03:35,383
‪或者窝在倒下的树底

40
00:03:38,052 --> 00:03:40,930
‪难以置信的是 有些就在露天环境里

41
00:03:46,519 --> 00:03:50,773
‪幼崽紧紧依偎在一起
‪靠着妈妈的温暖存活

42
00:03:56,988 --> 00:03:58,406
‪但这位妈妈

43
00:03:58,489 --> 00:04:01,242
‪选择了最舒适的巢穴

44
00:04:08,749 --> 00:04:10,751
‪当春天最终到来时

45
00:04:11,502 --> 00:04:13,379
‪它艰难的工作就会开始

46
00:04:16,549 --> 00:04:18,092
‪一头熊的成长环境

47
00:04:18,801 --> 00:04:20,886
‪会决定它的一生

48
00:04:27,601 --> 00:04:30,271
‪地球上只有八种熊

49
00:04:36,736 --> 00:04:39,196
‪分布在从亚洲丛林

50
00:04:39,947 --> 00:04:42,241
‪到北极冰原地区

51
00:04:44,493 --> 00:04:46,912
‪有些熊小得惊人

52
00:04:46,996 --> 00:04:48,539
‪体型只有一条狗那么大

53
00:04:49,248 --> 00:04:52,752
‪其他熊的体重则接近900公斤

54
00:04:55,504 --> 00:04:58,215
‪虽然所有熊都被归为食肉动物

55
00:04:58,299 --> 00:05:01,135
‪但大多数熊能吃到什么就吃什么

56
00:05:04,013 --> 00:05:07,600
‪但如何在合适的时间找到合适的食物

57
00:05:08,225 --> 00:05:10,728
‪只能由尽职的母亲教授

58
00:05:13,105 --> 00:05:15,858
‪每头熊在自己的家园都面临挑战

59
00:05:22,156 --> 00:05:24,450
‪所以 学会使用脑力

60
00:05:24,533 --> 00:05:26,160
‪和体力

61
00:05:27,536 --> 00:05:29,413
‪对于生存而言至关重要

62
00:05:39,256 --> 00:05:40,633
‪北极的冬天

63
00:05:43,969 --> 00:05:44,929
‪一片肃杀

64
00:05:47,264 --> 00:05:48,224
‪死气沉沉

65
00:05:50,559 --> 00:05:51,811
‪不过

66
00:05:51,894 --> 00:05:53,187
‪也并不完全如此

67
00:05:53,729 --> 00:05:58,359
‪（挪威 斯瓦尔巴）

68
00:06:13,165 --> 00:06:15,167
‪即使在零下40度

69
00:06:15,960 --> 00:06:17,795
‪北极熊的保温性能也很好

70
00:06:18,712 --> 00:06:20,423
‪它外有一层皮毛

71
00:06:21,006 --> 00:06:23,968
‪内有一层
‪像男人胳膊那么粗厚的脂肪毯

72
00:06:29,765 --> 00:06:32,268
‪北极熊永远不用冬眠

73
00:06:33,185 --> 00:06:35,855
‪冬天是它们狩猎的季节

74
00:06:39,567 --> 00:06:41,694
‪海豹是它们最喜欢的猎物

75
00:06:42,862 --> 00:06:46,740
‪北极熊利用它们惊人的嗅觉

76
00:06:46,824 --> 00:06:49,493
‪探测距离遥远的海豹

77
00:06:56,959 --> 00:06:59,170
‪这头雄性北极熊闻到了一股气味

78
00:06:59,962 --> 00:07:01,964
‪但那不是猎物

79
00:07:03,674 --> 00:07:05,468
‪而是其他熊

80
00:07:10,598 --> 00:07:14,810
‪众所周知 雄性北极熊会杀死
‪非自己所生的幼崽

81
00:07:17,521 --> 00:07:20,691
‪这头妈妈年轻但接近成年的幼崽

82
00:07:20,774 --> 00:07:22,234
‪并不怎么娇弱

83
00:07:23,652 --> 00:07:24,612
‪不过

84
00:07:24,695 --> 00:07:26,530
‪最好还是保持距离

85
00:07:31,911 --> 00:07:34,121
‪在能够自力更生之前

86
00:07:34,205 --> 00:07:36,957
‪它们需要完善自己的狩猎技能

87
00:07:41,837 --> 00:07:43,923
‪这可能是

88
00:07:44,924 --> 00:07:47,760
‪妈妈的一次授课机会

89
00:08:05,110 --> 00:08:06,695
‪迎风接近

90
00:08:09,114 --> 00:08:10,699
‪使用伪装

91
00:08:15,704 --> 00:08:17,581
‪潜入攻击范围

92
00:08:58,330 --> 00:09:00,249
‪经过每次成功的狩猎

93
00:09:00,332 --> 00:09:02,876
‪妈妈都会帮助它的幼崽变得更强壮

94
00:09:02,960 --> 00:09:04,169
‪更聪明

95
00:09:07,423 --> 00:09:11,218
‪一旦幼崽离开妈妈 这些课程将会

96
00:09:11,802 --> 00:09:13,887
‪决定生死

97
00:09:22,771 --> 00:09:26,984
‪（美国 马萨诸塞州）

98
00:09:27,943 --> 00:09:31,280
‪熊从离开巢穴那天起
‪就开始向妈妈学习

99
00:09:41,915 --> 00:09:45,044
‪春天终于来到黑熊一家门前

100
00:09:46,503 --> 00:09:49,256
‪大自然正在召唤它们

101
00:09:55,179 --> 00:09:59,099
‪熊妈妈自秋天以来
‪减掉了超过45公斤的脂肪

102
00:09:59,850 --> 00:10:01,518
‪几乎是它体重的一半

103
00:10:02,102 --> 00:10:04,021
‪所以它已经准备好开始行动了

104
00:10:06,607 --> 00:10:09,068
‪但幼崽吃饱喝足

105
00:10:09,151 --> 00:10:12,488
‪似乎不那么着急

106
00:10:19,036 --> 00:10:21,372
‪这是一个全新的世界

107
00:10:23,957 --> 00:10:26,043
‪攀登是与生俱来的技能

108
00:10:27,169 --> 00:10:30,547
‪即便如此
‪这条路还是有点像障碍赛道

109
00:10:48,691 --> 00:10:50,192
‪从第一次跨栏开始…

110
00:10:52,444 --> 00:10:53,862
‪妈妈就支持着它们

111
00:10:57,616 --> 00:10:59,868
‪它自己既是供养者

112
00:10:59,952 --> 00:11:02,246
‪也是教导者和保护者

113
00:11:04,540 --> 00:11:06,375
‪责任重大

114
00:11:07,126 --> 00:11:10,337
‪大约有三分之一的幼崽活不过第一年

115
00:11:17,136 --> 00:11:19,513
‪它们会面临的一个最大危险

116
00:11:20,431 --> 00:11:21,932
‪就是其他熊

117
00:11:22,433 --> 00:11:26,812
‪（美国 阿拉斯加州）

118
00:11:30,607 --> 00:11:33,986
‪棕熊 有时被称为灰熊

119
00:11:34,069 --> 00:11:36,905
‪已经从山上的冬穴下来

120
00:11:39,199 --> 00:11:42,536
‪它们聚集在沿海的草地上吃莎草

121
00:11:44,455 --> 00:11:48,292
‪熊不像猫科动物或犬科动物那样
‪保卫自己的领地

122
00:11:49,334 --> 00:11:51,587
‪但是它们仍然知道谁是老大

123
00:11:56,633 --> 00:11:59,094
‪这头年老的雄性霸主

124
00:11:59,178 --> 00:12:02,556
‪多年来一直对这片牧场拥有主权

125
00:12:10,522 --> 00:12:12,483
‪它需要增加体重

126
00:12:13,692 --> 00:12:16,487
‪这样繁殖季节到来时 它才能和任何

127
00:12:16,570 --> 00:12:18,655
‪敢于挑战自己的棕熊对抗

128
00:12:28,874 --> 00:12:32,628
‪这片草的肌肉发育蛋白含量高得惊人

129
00:12:37,674 --> 00:12:40,719
‪但如果你比一般熊更聪明

130
00:12:40,803 --> 00:12:43,514
‪就能找到更多富含营养的食物

131
00:12:50,354 --> 00:12:52,898
‪这位妈妈要带自己的幼崽

132
00:12:52,981 --> 00:12:56,193
‪享受一次独一无二的的进餐体验

133
00:13:03,408 --> 00:13:06,870
‪泥泞的海滩可能看起来荒凉贫瘠

134
00:13:13,085 --> 00:13:14,878
‪但是稍微挖掘一下

135
00:13:14,962 --> 00:13:16,922
‪就能发现下面的宝藏

136
00:13:23,262 --> 00:13:25,013
‪一旦找到一只蚌蛤

137
00:13:25,848 --> 00:13:27,599
‪就需要去壳

138
00:13:28,475 --> 00:13:30,769
‪这是一项出奇精细的操作

139
00:13:36,650 --> 00:13:38,819
‪不是所有的熊都有这个本事

140
00:13:40,112 --> 00:13:42,155
‪它是从自己妈妈那里学来的

141
00:13:43,198 --> 00:13:45,117
‪现在它要传授下去

142
00:13:50,247 --> 00:13:51,498
‪退潮时

143
00:13:51,582 --> 00:13:55,127
‪有天赋的蚌蛤捕手
‪可能收获100只味鲜肉美的小食

144
00:14:00,966 --> 00:14:02,968
‪这比起在同一时间吃草

145
00:14:03,051 --> 00:14:05,512
‪能获取更多蛋白质

146
00:14:10,809 --> 00:14:15,022
‪教授女儿本领 就能使它在
‪竞争激烈的世界中占得先机

147

‪一头陌生的棕熊

148
00:14:39,421 --> 00:14:40,714
‪还是撤退吧

149
00:14:43,842 --> 00:14:45,385
‪又一节重要的课程

150
00:14:46,094 --> 00:14:48,680
‪尽量避免对抗

151
00:14:51,892 --> 00:14:55,103
‪愤怒的熊有着山崩地裂的力量

152
00:15:08,784 --> 00:15:10,494
‪即便对手体型更大

153
00:15:11,203 --> 00:15:13,038
‪也绝对招架不住熊

154
00:15:15,874 --> 00:15:17,834
‪或它的爪子

155
00:15:19,503 --> 00:15:22,881
‪熊爪长达10厘米 是极其可怕的武器

156
00:15:25,801 --> 00:15:28,762
‪但它们也是多用途工具

157
00:15:30,180 --> 00:15:31,473
‪攀爬钉

158
00:15:33,600 --> 00:15:34,726
‪铁铲

159
00:15:35,560 --> 00:15:36,812
‪冰钩

160
00:15:37,688 --> 00:15:39,356
‪甚至是镀银餐具

161
00:15:41,900 --> 00:15:44,236
‪需要好好抓痒的时候

162
00:15:46,029 --> 00:15:47,447
‪什么都比不上自己的爪子

163
00:15:49,741 --> 00:15:51,576
‪有些最长的爪子

164
00:15:51,660 --> 00:15:53,996
‪长在体型最小的熊身上

165
00:15:56,206 --> 00:15:58,959
‪虽然大小只是棕熊的十分之一

166
00:15:59,042 --> 00:16:03,046
‪马来熊却是丛林生存方面的专家

167
00:16:03,964 --> 00:16:08,135
‪（马来西亚 婆罗洲）

168
00:16:10,178 --> 00:16:12,889
‪在杂乱的植被中寻找食物

169
00:16:12,973 --> 00:16:14,016
‪并不容易

170
00:16:20,647 --> 00:16:23,900
‪但凭着几乎无与伦比的嗅觉…

171
00:16:27,237 --> 00:16:29,156
‪它跟着自己的鼻子走

172
00:16:51,219 --> 00:16:54,222
‪它已经缩小了香甜之气的来源范围

173
00:16:55,557 --> 00:16:58,310
‪现在只有一个问题了

174
00:17:00,020 --> 00:17:02,022
‪气味来自大上面

175
00:17:05,692 --> 00:17:07,736
‪四层楼高

176
00:17:09,863 --> 00:17:11,698
‪但是马来熊

177
00:17:11,782 --> 00:17:13,325
‪很喜欢蜂蜜

178
00:17:18,622 --> 00:17:21,333
‪幸好它们还是冠军级别的攀岩手

179
00:17:28,465 --> 00:17:31,134
‪那些又弯又长的爪子

180
00:17:31,218 --> 00:17:32,677
‪抓地力很好

181
00:17:33,678 --> 00:17:37,557
‪像狗一般大小的身躯让它轻盈敏捷

182
00:17:38,308 --> 00:17:39,142
‪可是

183
00:17:40,310 --> 00:17:42,229
‪它爬错树了

184
00:17:46,441 --> 00:17:47,776
‪现在

185
00:17:48,777 --> 00:17:50,529
‪它有了一个竞争者

186

‪或者没有？

187
00:18:08,922 --> 00:18:12,926
‪马来熊也喜欢享用腐烂的原木

‪趁着另一只熊分心

189
00:18:29,151 --> 00:18:30,986
‪换树的机会来了

190
00:18:47,002 --> 00:18:48,587
‪蜜蜂很生气

191
00:18:48,670 --> 00:18:50,255
‪但是幸好没有蛰针

192
00:18:53,341 --> 00:18:54,467
‪终于

193
00:18:56,595 --> 00:18:58,221
‪它找到了宝藏

194
00:19:03,810 --> 00:19:06,688
‪那些爪子也是使用方便的蜂蜜勺

195
00:19:13,486 --> 00:19:16,406
‪剩下的就由25厘米的舌头来完成

196
00:19:23,038 --> 00:19:25,624
‪只要是在丛林里觅食

197
00:19:25,707 --> 00:19:28,543
‪马来熊必定“舌”到成功

198
00:19:37,219 --> 00:19:40,680
‪但由于赖以生存的森林遭到砍伐
‪被用来耕地…

199
00:19:42,933 --> 00:19:45,060
‪马来熊逐渐无家可归

‪甚至

203
00:20:03,995 --> 00:20:06,748

‪大熊猫一生中大部分时间

206
00:20:45,245 --> 00:20:47,330
‪只吃一样东西

‪爪子上有籽骨的熊 有点像大拇指

213
00:21:18,945 --> 00:21:22,324
‪做竹子热狗再合适不过了

214
00:21:23,825 --> 00:21:27,370
‪素食似乎是个奇怪的选择

00:21:27,454 --> 00:21:29,331
‪熊猫本来已经进化成了食肉动物

216
00:21:33,043 --> 00:21:35,378
‪但是因为竹子资源丰富

217
00:21:35,462 --> 00:21:37,088
‪而且常年生长

218
00:21:37,172 --> 00:21:41,134
‪数百万年来
‪它们投向了更容易的选择

219
00:21:43,970 --> 00:21:45,263
‪问题是

220
00:21:45,347 --> 00:21:48,725
‪它们的肠道还没有完全适应消化竹子

221
00:21:51,144 --> 00:21:53,146
‪因此它只能靠大量进食

222
00:21:53,229 --> 00:21:54,814
‪才能生存

223
00:21:56,733 --> 00:21:58,360
‪所以就几乎做不了其他事了

‪妈妈必须要留心它们
‪听着它们的声音

238
00:23:31,911 --> 00:23:33,663

‪但它没有领会到这一信息

246
00:24:27,550 --> 00:24:29,844
‪那声咳嗽的意思是“攀爬”

247
00:24:51,950 --> 00:24:54,827

‪在它确定海岸安全之前

255
00:25:37,745 --> 00:25:39,539
‪幼崽会远离地面

256
00:25:43,668 --> 00:25:46,087
‪这是继续进行攀岩练习的一次机会

257
00:25:47,171 --> 00:25:50,049

‪但是对于一些眼镜熊来说

267
00:26:45,396 --> 00:26:46,397

‪现实生活中的帕丁顿熊

270
00:26:57,450 --> 00:27:00,203
‪但这里不需要穿粗呢外衣或戴防雨帽

271
00:27:01,120 --> 00:27:03,539
‪最高的山脉挡住了云层…

272
00:27:07,960 --> 00:27:10,963
‪形成了高海拔的沙漠

00:27:55,842 --> 00:27:58,136
‪它可以在这里休息一整天

278
00:28:03,516 --> 00:28:05,768
‪若一只雄性独占浴池

279
00:28:06,436 --> 00:28:09,021
‪其他雄性就必须更加足智多谋

280
00:28:24,495 --> 00:28:26,581
‪这头熊妈妈在向幼崽展示

281
00:28:26,664 --> 00:28:28,082
‪即使是树干

282
00:28:28,166 --> 00:28:29,834
‪也有助于生存

283
00:28:30,918 --> 00:28:34,255
‪相比同体型的任何熊来说
‪它的下巴最有力

284
00:28:34,338 --> 00:28:37,967
‪所以能很容易把树干撕裂
‪喝到里面的水分

285
00:28:47,226 --> 00:28:50,271
‪食物和水如此稀缺

286
00:28:50,354 --> 00:28:51,898
‪它必须保存体力

287
00:28:52,690 --> 00:28:54,275
‪经常休息

288
00:28:57,403 --> 00:28:59,489
‪离开地面会更凉爽一点

289
00:28:59,572 --> 00:29:01,908
‪但细长的树枝不能提供太多支撑

290
00:29:03,618 --> 00:29:05,411
‪所以它做了一件

‪其他熊没有做过的事

292
00:29:14,796 --> 00:29:16,672

293
00:29:25,973 --> 00:29:28,142

‪它需要额外的体重

305
00:30:14,105 --> 00:30:17,191
‪体型高大和心狠手辣使得它成为老大

306
00:30:17,984 --> 00:30:20,027
‪统治着最佳进食地点

307
00:30:20,111 --> 00:30:22,154
