00:00:13,513 --> 00:00:15,306
‎一百万只牛羚

2
00:00:16,099 --> 00:00:18,810
‎在迁徙一千公里后

3
00:00:18,893 --> 00:00:22,772
‎在一年一度的迁徙中
‎面临着最大的障碍

4
00:00:25,442 --> 00:00:27,610
‎坦桑尼亚的马拉河

5
00:00:34,659 --> 00:00:39,456
‎同行的斑马中
‎有带着马驹的雌性斑马

6
00:00:47,088 --> 00:00:48,506
‎等候它们的是…

7
00:00:51,676 --> 00:00:52,677
‎鳄鱼

8
00:01:03,354 --> 00:01:07,067
‎小斑马越小 其存活几率就越小

9
00:01:11,488 --> 00:01:13,740
‎作为年纪最小的马驹之一

10
00:01:21,164 --> 00:01:24,167
‎它尽可能地紧挨着母亲

11
00:01:24,834 --> 00:01:28,755
‎因为落单的斑马难以活命

12
00:01:34,219 --> 00:01:35,970
‎在它艰难地跟上大部队之际

13
00:01:45,105 --> 00:01:46,856
‎所能做的 只有踢水

14
00:01:48,483 --> 00:01:50,985
‎此时 它的同伴正直面危险

15
00:02:08,419 --> 00:02:11,923
‎所幸的是 鳄鱼分心的时间刚好够长

16
00:02:12,006 --> 00:02:14,968
‎让马驹有足够的时间跟上母亲…

17
00:02:17,178 --> 00:02:21,224
‎成功过河后 它们继续与
‎地球上最大的畜群一起迁徙

18
00:02:32,360 --> 00:02:39,325
‎片名：我们的星球 2

19
00:02:43,204 --> 00:02:46,749
‎（第三章 下一世代）

20
00:02:59,179 --> 00:03:02,682
‎有些动物通过踏上令人惊叹的旅程

21
00:03:03,516 --> 00:03:06,519
‎来给它们的幼崽最好的人生起点

22
00:03:08,188 --> 00:03:12,358
‎但重要的不仅是目的地
‎还有何时出发

23
00:03:15,945 --> 00:03:18,823
‎墨西哥的太平洋海岸

24
00:03:28,416 --> 00:03:30,710
‎这片海滩看起来很荒凉

25
00:03:35,340 --> 00:03:37,300
‎但在沙地之下

26
00:03:37,884 --> 00:03:40,845
‎成千上万的动物在迁徙

27
00:03:52,190 --> 00:03:54,609
‎这是榄蠵龟的幼崽

28
00:03:59,030 --> 00:04:04,118
‎十月份之际
‎沙地的温度正好适合它们冒出来

29
00:04:07,247 --> 00:04:09,207
‎这是第一只冒出沙地表面的幼崽

30
00:04:10,500 --> 00:04:11,834
‎它一动不动

31
00:04:16,673 --> 00:04:19,384
‎它所做的任何动作都可能引起注意

32
00:04:22,220 --> 00:04:23,763
‎所以它们必须等同伴一起出发

33
00:04:27,934 --> 00:04:29,477
‎它们即将踏上

34
00:04:29,560 --> 00:04:32,981
‎生命中最危险的旅程

35
00:04:35,650 --> 00:04:38,486
‎因此 最好是成群结队出发

36
00:04:59,841 --> 00:05:01,175
‎对猎兽来说…

37
00:05:04,012 --> 00:05:06,389
‎这是一年中最盛大的宴席

38
00:05:17,567 --> 00:05:21,195
‎猎物们把一半冒出来的幼崽
‎都带到了海滩上

39
00:05:22,739 --> 00:05:26,743
‎而小乌龟接踵而至 其数量之多

40
00:05:26,826 --> 00:05:29,412
‎捕食者根本跟不上脚步

41
00:05:30,538 --> 00:05:34,292
‎而这是它们下海的唯一机会

42
00:06:21,506 --> 00:06:23,341
‎眼看潮水要退去了

43
00:06:28,971 --> 00:06:33,059
‎小乌龟的处境变得越来越危险

44
00:06:36,020 --> 00:06:38,815
‎跟随其他乌龟是它们唯一的机会

45
00:06:55,206 --> 00:06:57,166
‎有些乌龟成功到达了浅滩

46
00:07:00,586 --> 00:07:03,047
‎但即便是现在 它们也命悬一线

47
00:07:16,436 --> 00:07:17,770
‎那些存活下来的乌龟

48
00:07:18,396 --> 00:07:21,315
‎在接下来的24小时里

49
00:07:21,399 --> 00:07:23,276
‎会不顾一切 奋力游动

50
00:07:25,403 --> 00:07:30,199
‎在游动的过程中
‎乌龟的身上有地球磁场的标记

51
00:07:31,826 --> 00:07:36,581
‎一到繁衍的季节
‎这种心理标记可以指引它们回来

52
00:07:42,378 --> 00:07:44,338
‎每一只榄蠵龟

53
00:07:44,422 --> 00:07:48,009
‎生命中的前15年都在太平洋度过

54
00:07:48,634 --> 00:07:51,053
‎它们在此独自觅食和成长

55
00:07:52,263 --> 00:07:55,683
‎每只海龟都会游几十万公里

56
00:07:56,309 --> 00:07:59,145
‎直到它们改变航线的那天…

57
00:08:01,606 --> 00:08:05,860
‎此后 它们将开始长途跋涉
‎以回到其出生的海滩上

58
00:08:10,615 --> 00:08:12,950
‎这只十几岁的海龟

59
00:08:13,534 --> 00:08:15,453
‎十多年来第一次

60
00:08:16,078 --> 00:08:18,581
‎与同类见面

61
00:08:26,506 --> 00:08:28,716
‎25万只海龟

62
00:08:31,511 --> 00:08:34,472
‎汇聚成地球上规模最大的海龟集会

63
00:08:53,824 --> 00:08:57,912
‎在这里 这只雌龟在交配后
‎游上岸产卵

64
00:09:07,964 --> 00:09:10,466
‎它已经长大
‎不再是昔日弱小的幼龟了

65
00:09:11,467 --> 00:09:14,387
‎即便如此 对它来说
‎浅滩还是如往常一样危险

66
00:09:51,424 --> 00:09:52,383
‎陆地

67
00:09:53,968 --> 00:09:57,263
‎这是它15年来第一次踏上陆地

68
00:09:59,515 --> 00:10:02,977
‎它现在来这里 是有急事要做

69
00:10:08,316 --> 00:10:10,818
‎虽然雌龟已经准备好产卵

70
00:10:11,652 --> 00:10:13,863
‎它必须要先挖好安置卵的巢

71
00:10:18,284 --> 00:10:20,995
‎如果它把卵产在潮汐线之下

72
00:10:21,078 --> 00:10:22,288
‎幼龟会淹死

73
00:10:23,372 --> 00:10:25,249
‎但如果离海滩太远

74
00:10:25,333 --> 00:10:26,834
‎卵可能会干透

75
00:10:28,794 --> 00:10:31,881
‎因此 中间地带很受欢迎

76
00:10:38,888 --> 00:10:41,223
‎随着数以千计的成年海龟的到来

77
00:10:41,974 --> 00:10:44,727
‎在这里产下的卵中 多达80%

78
00:10:44,810 --> 00:10:49,315
‎会不小心被其它驻巢的雌龟破坏

79
00:10:57,865 --> 00:10:59,367
‎尽管产卵数量如此之多

80
00:11:00,951 --> 00:11:05,122
‎在此之中 数以百万计的卵
‎仍然会平安无事 深埋于沙地中

81
00:11:10,544 --> 00:11:13,089
‎在它产下了一百多颗卵之后

82
00:11:14,298 --> 00:11:17,259
‎工作就完成了

83
00:11:20,054 --> 00:11:23,057
‎但明年同一时间

84
00:11:23,140 --> 00:11:27,103
‎它会回到这处海滩 再次产卵

85
00:11:28,771 --> 00:11:32,316
‎往后余生 年复一年地继续

86
00:11:42,702 --> 00:11:45,538
‎大部分动物的旅程都是为了繁衍后代

87
00:11:45,621 --> 00:11:48,040
‎千年以来几乎不曾变过

88
00:11:54,380 --> 00:11:58,342
‎马尔维纳斯群岛
‎坐落在大西洋的某个偏远地区

89
00:11:58,426 --> 00:12:00,469
‎位于南美洲以东

90
00:12:10,855 --> 00:12:13,983
‎数千年以来

91
00:12:14,066 --> 00:12:15,526
‎象海豹一直来到这里繁衍后代

92
00:12:18,779 --> 00:12:21,490
‎但在十月下旬时

93
00:12:21,574 --> 00:12:23,117
‎只有海豹幼崽在这片海滩上

94
00:12:25,035 --> 00:12:29,498
‎它们的母亲在数周前就离开了
‎它们现在必须自食其力

95
00:12:34,795 --> 00:12:37,131
‎不过几天后 它们也会离开

96
00:12:37,214 --> 00:12:41,093
‎以开始它们在深海中
‎海洋漫游者的旅途

97
00:12:46,599 --> 00:12:49,560
‎但这些幼崽还没学会游泳

98
00:12:54,857 --> 00:12:57,485
‎这里正好有处有遮挡的海滨泳池

99
00:12:57,568 --> 00:13:00,446
‎似乎是个学游泳的好去处

100
00:13:12,500 --> 00:13:14,877
‎它们在这里慢慢熟悉海洋后

101
00:13:19,131 --> 00:13:22,468
‎终于能够本能地游动起来

102
00:13:23,219 --> 00:13:27,223
‎然而它们还没意识到海洋的危险之处

103
00:13:33,229 --> 00:13:34,104
‎虎鲸

104
00:13:35,064 --> 00:13:36,232
‎又称杀人鲸

105
00:13:43,739 --> 00:13:46,492
‎它们可不是随便路过的鲸鱼群

106
00:13:47,451 --> 00:13:52,581
‎这群虎鲸游了几百公里
‎为的就是正好在此刻来到这里

107
00:13:56,502 --> 00:13:57,670
‎二十年前

108
00:13:57,753 --> 00:14:01,924
‎领头的雌虎鲸意外发现了
‎海豹幼崽去泳池玩耍的时间

109
00:14:03,050 --> 00:14:07,346
‎不仅如此 它还发现
‎随着潮水的上涨 它也能到达那里

110
00:14:13,853 --> 00:14:16,063
‎但在那之前 雌虎鲸必须守株待兔

111
00:14:19,024 --> 00:14:20,860
‎如果选错袭击的时机

112
00:14:20,943 --> 00:14:23,445
‎它就会在岩石上搁浅

113
00:14:32,329 --> 00:14:33,998
‎在半潮的时候

114
00:14:34,081 --> 00:14:37,751
‎上涨的潮水刚好够深
‎能容下一只虎鲸

115
00:14:53,893 --> 00:14:56,604
‎即便危险就在眼前

116
00:14:58,230 --> 00:15:00,733
‎这些幼崽却一无所知

117
00:15:16,165 --> 00:15:18,792
‎雌虎鲸只需要一只在水里的海豹幼崽

118
00:15:18,876 --> 00:15:21,921
‎但对它而言
‎海水还是太浅 不够安全

119
00:15:25,341 --> 00:15:26,467
‎雌虎鲸只要转错一个弯

120
00:15:27,676 --> 00:15:29,136
‎就会搁浅

121
00:15:35,809 --> 00:15:38,187
‎此刻 海豹幼崽已经触手可及

122
00:15:42,316 --> 00:15:44,902
‎雌虎鲸全神贯注地观察

123
00:15:46,153 --> 00:15:49,031
‎等幼崽靠得足够近
‎它才可以一口咬住

124
00:16:14,515 --> 00:16:18,352
‎虎鲸叼着还活蹦乱跳的幼崽回到海里

125
00:16:24,817 --> 00:16:28,862
‎这只雌虎鲸
‎是唯一一只以这种方式捕猎的

126
00:16:31,240 --> 00:16:34,410
‎而它做的这些全是为了它的家人

127
00:16:39,164 --> 00:16:42,584
‎被捕的海豹幼崽苟活了好几个小时

128
00:16:48,716 --> 00:16:52,219
‎这些虎鲸已经学会利用

129
00:16:52,302 --> 00:16:55,055
‎海豹每年来这里繁殖的时机

130
00:16:56,974 --> 00:16:59,643
‎而同样让人惊叹的是

131
00:17:00,227 --> 00:17:03,981
‎虎鲸十分清楚它们每年何时回来

132
00:17:20,122 --> 00:17:22,791
‎对某些动物来说

133
00:17:23,459 --> 00:17:25,878
‎安全繁衍的前提是避开兽群

134
00:17:33,010 --> 00:17:34,511
‎新西兰

135
00:17:34,595 --> 00:17:38,724
‎是最后一个人类可接触到的宜居之地

136
00:17:46,106 --> 00:17:46,940
‎为了来到此地

137
00:17:47,024 --> 00:17:51,820
‎波利尼西亚人
‎必须跨越几千公里的公海

138
00:17:53,030 --> 00:17:55,949
‎动物也需要不远千里前来

139
00:18:01,205 --> 00:18:05,751
‎尽管如此 每年有一位访客

140
00:18:05,834 --> 00:18:08,629
‎会横跨南大洋六千公里

141
00:18:09,588 --> 00:18:12,508
‎来到这座岛屿最为隐秘的角落

142
00:18:26,063 --> 00:18:29,191
‎它既害羞又神秘

143
00:18:40,494 --> 00:18:43,372
‎这是峡湾地区的黄眉企鹅

144
00:18:44,373 --> 00:18:46,333
‎又称丛林企鹅

145
00:18:47,793 --> 00:18:50,504
‎企鹅爸爸在照顾它八周大的幼崽

146
00:18:51,547 --> 00:18:55,217
‎此刻 它的另一半正在海里觅食

147
00:18:56,593 --> 00:19:00,389
‎如果企鹅爸爸做得不够出色
‎企鹅妈妈可能会抛下它

148
00:19:07,771 --> 00:19:10,691
‎企鹅的离婚率确实很高

149
00:19:14,111 --> 00:19:16,655
‎所以企鹅爸爸最好不让其他动物靠近

150
00:19:22,536 --> 00:19:27,249
‎企鹅妈妈在觅食忙活了一天后
‎回到了海岸

151
00:19:30,335 --> 00:19:32,754
‎但要上岸绝非易事

152
00:19:41,805 --> 00:19:43,891
‎问题在于把握时机

153
00:19:51,481 --> 00:19:52,649
‎差点儿！

154
00:20:10,542 --> 00:20:11,710
‎做得很好

155
00:20:14,671 --> 00:20:16,215
‎为了回到嗷嗷待哺的幼崽身边

156
00:20:17,257 --> 00:20:19,551
‎企鹅妈妈必须跨过巨石

157
00:20:20,677 --> 00:20:21,595
‎越过根茎

158
00:20:22,846 --> 00:20:24,014
‎跳过沟壑

159
00:20:39,029 --> 00:20:42,699
‎这就是企鹅风格的外卖服务

160
00:20:46,912 --> 00:20:49,623
‎企鹅爸爸只能羡慕地看着

161
00:20:53,877 --> 00:20:57,506
‎随着幼崽的成长
‎它的食欲也跟着大增

162
00:20:59,508 --> 00:21:01,468
‎为了满足它们的需求

163
00:21:01,551 --> 00:21:05,347
‎企鹅妈妈必须一次又一次

164
00:21:06,515 --> 00:21:07,766
‎克服重重障碍

165
00:21:09,434 --> 00:21:10,727
‎穿过树林 来到海里捕食

166
00:21:22,364 --> 00:21:25,951
‎为了抚养幼崽
‎它需要走完一场马拉松的距离

167
00:21:26,034 --> 00:21:28,870
‎以及游一千多公里

168
00:21:30,163 --> 00:21:33,834
‎企鹅妈妈会因此减掉多达一半的体重

169
00:21:38,380 --> 00:21:40,716
‎但这并不能阻止它的步伐

170
00:22:00,610 --> 00:22:03,739
‎随后 漫长的十周过去了

171
00:22:04,823 --> 00:22:06,658
‎企鹅妈妈终于受够了

172
00:22:09,536 --> 00:22:12,205
‎因为外卖服务结束了

173
00:22:12,289 --> 00:22:15,292
‎饥肠辘辘的幼崽被迫到海洋觅食

174
00:22:19,963 --> 00:22:22,674
‎好在离岸不远处有充足的食物

175
00:22:23,675 --> 00:22:26,887
‎但奇怪的是 它跟着其它企鹅游走了

176
00:22:26,970 --> 00:22:29,556
‎在往南极洲的半路上

177
00:22:29,639 --> 00:22:31,933
‎企鹅幼崽足足游了数千公里

178
00:22:33,602 --> 00:22:37,481
‎这是企鹅史上最长的单程旅程

179
00:22:37,981 --> 00:22:40,776
‎而这趟旅程可能毫无意义

180
00:22:41,318 --> 00:22:45,280
‎（南极洲）

181
00:22:45,364 --> 00:22:49,242
‎有人认为
‎企鹅的祖先早在两百万年前

182
00:22:49,326 --> 00:22:52,120
‎只能在这里觅食的时候
‎就会这样长距离迁徙了

183
00:22:52,871 --> 00:22:55,791
‎而这显然是一个难以打破的惯例

184
00:23:05,467 --> 00:23:06,468
‎在十一月

185
00:23:06,551 --> 00:23:10,680
‎印度洋的日照增加
‎海水温度因此上升

186
00:23:11,181 --> 00:23:13,683
‎季风也随之而来

187
00:23:15,227 --> 00:23:18,146
‎这股季风会途经圣诞岛

188
00:23:21,149 --> 00:23:25,946
‎它带来的湿度上升
‎唤醒了沉睡的大军

189
00:23:37,833 --> 00:23:39,709
‎它们就是圣诞岛红蟹

190
00:23:39,793 --> 00:23:42,587
‎红蟹现在几乎全在陆上生活

191
00:23:44,464 --> 00:23:45,632
‎但要呼吸的话

192
00:23:45,715 --> 00:23:48,093
‎它们的腮部仍需要水分

193
00:23:49,010 --> 00:23:51,805
‎并需要在海中产卵

194
00:23:53,932 --> 00:23:59,563
‎因此 在过去的20万年中
‎红蟹每年都会长途跋涉前去海岸

195
00:24:01,940 --> 00:24:05,026
‎然而近来 发生了很多变化

196
00:24:12,242 --> 00:24:14,578
‎比如说 红蟹现在身边有帮手了

197
00:24:29,092 --> 00:24:32,554
‎当地人还建造了特殊的桥梁

198
00:24:32,637 --> 00:24:36,725
‎这种桥可以让红蟹
‎不紧不慢地穿过最繁忙的道路

199
00:24:38,101 --> 00:24:40,979
‎此外 当地人还建立了
‎给它们指路的地下网络

200
00:24:46,735 --> 00:24:48,403
‎红蟹为了赶上涨潮

201
00:24:48,904 --> 00:24:51,114
‎会加快它们的步伐

202
00:24:55,702 --> 00:24:59,915
‎一夜之间 四百万只红蟹来到海岸

203
00:25:08,381 --> 00:25:12,802
‎每只雌蟹会在浪花中诞下十万颗卵

204
00:25:25,857 --> 00:25:30,111
‎这些卵会立刻孵化为自由游动的幼体

205
00:25:34,032 --> 00:25:39,120
‎然而大多数年头
‎绝大部分幼体会被吃掉

206
00:25:39,788 --> 00:25:41,540
‎或被卷进深海中 有去无回

207
00:25:44,292 --> 00:25:47,629
‎但运气好的话 下一个月的涨潮之时

208
00:25:47,712 --> 00:25:50,924
‎它们会被冲刷回岛屿的海岸上

209
00:25:53,635 --> 00:25:57,722
‎（南大西洋）

210
00:25:57,806 --> 00:26:00,183
‎再往南数千公里处

211
00:26:00,267 --> 00:26:02,978
‎另一次首航即将开始

212
00:26:08,400 --> 00:26:09,609
‎在十一月下旬 仲夏时分

213
00:26:10,151 --> 00:26:12,988
‎于世界的尽头

214
00:26:15,490 --> 00:26:20,120
‎位于美洲最南端的巴塔哥尼亚

215
00:26:26,418 --> 00:26:30,922
‎只有一种大型陆地捕食动物
‎住在在如此遥远的南边

216
00:26:33,592 --> 00:26:34,551
‎美洲狮

217
00:26:41,099 --> 00:26:42,642
‎它叫马奇托

218
00:26:43,351 --> 00:26:44,728
‎那只灰色的美洲狮

219
00:26:46,062 --> 00:26:50,609
‎它一岁了
‎即将要面临一生中最大的考验

220
00:26:51,985 --> 00:26:53,403
‎然而它并不知道有这回事

221
00:27:02,370 --> 00:27:04,623
‎小雄狮和它的妹妹 妮娜

222
00:27:05,248 --> 00:27:10,795
‎都到了应该分开的年龄
‎并各自寻找自己的领地

223
00:27:21,348 --> 00:27:23,391
‎然而公狮之间激烈的竞争

224
00:27:23,475 --> 00:27:27,646
‎意味着马奇托
‎必须比它妹妹走得更远

225
00:27:31,441 --> 00:27:34,986
‎但现在它们俩都必须习得狩猎之道

226
00:27:44,829 --> 00:27:46,206
‎就算是狮子妈妈亲自出马

227
00:27:47,540 --> 00:27:49,542
‎捕猎一只比它体型大三倍的…

228
00:27:52,545 --> 00:27:55,548
‎成年公原驼

229
00:27:56,174 --> 00:27:58,343
‎也是巨大的挑战

230
00:28:00,595 --> 00:28:02,055
‎但雌狮对捕猎很在行

231
00:28:04,933 --> 00:28:06,935
‎此时幼狮们正虎视眈眈

232
00:28:15,360 --> 00:28:19,072
‎为了成功捕捉猎物
‎雌狮必须出现在猎物几米距离内

233
00:28:46,307 --> 00:28:49,894
‎而不管猎物做什么挣扎
‎它都要紧紧抓住对方

234
00:29:19,591 --> 00:29:22,844
‎此刻 幼狮应该尽情享用免费的美食

235
00:29:24,095 --> 00:29:27,766
‎它们饭来张口的好日子快结束了

236
00:29:34,022 --> 00:29:36,983
‎它们的母亲已经为它们做了
‎所有力所能及的事

237
00:29:40,737 --> 00:29:42,363
‎在同居一年后

238
00:29:42,447 --> 00:29:45,492
‎狮子妈妈的领地不再是它们的了

239
00:29:54,793 --> 00:29:57,045
‎小狮子是时候离开了

240
00:30:07,055 --> 00:30:10,850
‎几个星期以来 这对兄妹相依为命

241
00:30:11,726 --> 00:30:14,854
‎尽管如此 它们俩很快就要分别

242
00:30:16,606 --> 00:30:18,274
‎雌狮 妮娜

243
00:30:18,358 --> 00:30:21,653
‎得以住在离它母亲领地的不远处

244
00:30:23,363 --> 00:30:25,824
‎而马奇托没这么好命

245
00:30:30,870 --> 00:30:33,373
‎因为雄狮的领地要大得多

246
00:30:33,456 --> 00:30:35,333
‎为了找到足够大的空地

247
00:30:35,416 --> 00:30:38,253
‎它可能要走数百公里的路

248
00:30:49,597 --> 00:30:51,724
‎这是小雄狮有生以来第一次

249
00:30:52,642 --> 00:30:54,227
‎独自在外

250
00:31:01,442 --> 00:31:03,111
‎在迁徙数周后

251
00:31:03,736 --> 00:31:05,154
‎小雄狮饿坏了

252
00:31:15,874 --> 00:31:17,333
‎虽然看过母亲捕捉猎物的过程

253
00:31:18,334 --> 00:31:20,420
‎但它学的知识足够派上用场了吗？

254
00:31:31,806 --> 00:31:32,849
‎显然不够

255
00:31:37,103 --> 00:31:39,772
‎为了找到食物 小雄狮必须一直迁徙

256
00:31:40,815 --> 00:31:44,652
‎深入陌生的地带

257
00:31:52,285 --> 00:31:54,996
‎它会一直前进…

258
00:31:57,373 --> 00:32:01,753
‎直到确定嗅到的是新鲜猎物的气味

259
00:32:10,470 --> 00:32:11,846
‎但这股气味…

260
00:32:14,390 --> 00:32:16,100
‎来自一只大雄狮

261
00:32:46,673 --> 00:32:48,967
‎这只雄狮的体型是马奇托的两倍大…

262
00:32:52,804 --> 00:32:55,056
‎能在几秒内置小雄狮于死地

263
00:33:05,441 --> 00:33:08,361
‎但它现在太饿了 不能轻易放弃

264
00:33:26,879 --> 00:33:29,424
‎出乎意料的是 老狮子退让了

265
00:33:30,675 --> 00:33:32,719
‎允许小狮子享用美食

266
00:33:33,302 --> 00:33:36,514
‎这种行为在雄狮之间非常罕见

267
00:33:38,850 --> 00:33:42,145
‎马奇托的勇气
‎也许给它赢来了更多的时间

268
00:33:43,688 --> 00:33:46,774
‎而它的旅程才刚开始

269
00:33:52,572 --> 00:33:55,658
‎雄性美洲狮跑得又远又快

270
00:33:56,492 --> 00:34:00,830
‎因此 人们对于它们的独立生活
‎知之甚少

271
00:34:07,587 --> 00:34:11,591
‎有人认为 很少有美洲狮
‎第一年能独自存活下来

272
00:34:12,675 --> 00:34:15,386
‎幸运的话 小狮子会是其中一员

273
00:34:23,436 --> 00:34:26,898
‎（十二月）

274
00:34:33,863 --> 00:34:35,740
‎今天是平安夜

275
00:34:35,823 --> 00:34:39,494
‎这个时候的圣诞岛海岸呈鲜红色

276
00:34:42,872 --> 00:34:44,207
‎真是十年一遇

277
00:34:44,707 --> 00:34:48,544
‎洋流的方向恰到好处
‎小螃蟹可以顺着这股洋流回家了

278
00:34:50,797 --> 00:34:53,633
‎这是有史以来规模最大的回家之旅

279
00:34:55,426 --> 00:34:57,470
‎数十亿只小螃蟹挤在珊瑚礁上…

280
00:35:04,352 --> 00:35:06,062
‎当地的动物因此困惑不已

281
00:35:07,939 --> 00:35:10,525
‎小螃蟹想方设法

282
00:35:11,567 --> 00:35:13,236
‎回到陆地

283
00:35:17,698 --> 00:35:21,077
‎它们需要到达两公里外的森林

284
00:35:21,160 --> 00:35:25,581
‎因为那是小螃蟹父母的出生地
‎也是安全的归宿

285
00:35:26,999 --> 00:35:30,378
‎然而 它们的父母并不是针头般大小

286
00:35:33,464 --> 00:35:37,135
‎为了到达目的地
‎它们现在脱下外壳 换下潜水服

287
00:35:37,218 --> 00:35:39,929
‎换成更易于呼吸的东西

288
00:35:43,891 --> 00:35:44,725
‎小螃蟹准备好了

289
00:35:45,434 --> 00:35:47,770
‎但在离开海滩之前…

290
00:35:50,398 --> 00:35:53,317
‎一个不速之客突袭了它们

291
00:35:58,865 --> 00:35:59,824
‎这是妈妈吗？

292
00:36:04,912 --> 00:36:10,084
‎成年红蟹显然不太适合照顾幼崽

293
00:36:12,753 --> 00:36:15,798
‎这帮小螃蟹该离开海滩了
‎并且动作必须快

294
00:36:20,052 --> 00:36:23,598
‎为了离开这里 它们需要攀爬海堤

295
00:36:25,558 --> 00:36:29,103
‎它们眼中的海堤
‎就像我们眼中的摩天楼一样令人生畏

296
00:36:35,526 --> 00:36:39,030
‎爬上山顶之后
‎小螃蟹必须匍匐穿过小镇

297
00:36:46,078 --> 00:36:48,497
‎然而 作为几十亿大军的一员

298
00:36:48,581 --> 00:36:52,001
‎想保持低调并不容易

299
00:37:09,852 --> 00:37:12,605
‎小螃蟹只有芝麻般大小

300
00:37:12,688 --> 00:37:14,649
‎对它们来说 这个世界充满危险

301
00:37:16,025 --> 00:37:18,277
‎为了避免危险
‎小螃蟹需要注意自己的脚下

302
00:37:25,910 --> 00:37:27,411
‎它们终于到达了森林的边缘

303
00:37:27,495 --> 00:37:29,455
‎安全的归宿近在眼前

304
00:37:30,539 --> 00:37:32,416
‎但现在松懈下来还太早

305
00:37:36,337 --> 00:37:38,297
‎因为吃小螃蟹的

306
00:37:39,590 --> 00:37:41,509
‎黄疯蚁来了

307
00:37:45,012 --> 00:37:46,639
‎那些安全通过的小螃蟹

308
00:37:47,390 --> 00:37:49,892
‎可算可以在家过圣诞节了

309
00:37:53,771 --> 00:37:57,733
‎在接下来的五年里
‎它们会觅食和成长

310
00:37:58,484 --> 00:38:01,612
‎之后踏上重返海洋的旅程

311
00:38:02,238 --> 00:38:05,032
‎接着在海洋里产下自己的小螃蟹

312
00:38:12,206 --> 00:38:14,000
‎动物第一次踏上的旅程

313
00:38:14,083 --> 00:38:17,253
‎几乎总是最具挑战性的

314
00:38:18,713 --> 00:38:21,382
‎然而 其中有些旅程特别令人生畏

315
00:38:26,971 --> 00:38:28,931
‎就拿年轻的蓑羽鹤来说

316
00:38:29,015 --> 00:38:32,893
‎它们面临着
‎所有鸟类中最艰难的迁徙之一

317
00:38:37,481 --> 00:38:39,567
‎为了逃离冰封的蒙古

318
00:38:39,650 --> 00:38:43,404
‎蓑羽鹤得南下到印度过冬

319
00:38:45,781 --> 00:38:49,076
‎但那里的旅程并不总是这般艰难

320
00:38:56,125 --> 00:38:57,918
‎在四千五百万年前

321
00:38:58,002 --> 00:39:00,629
‎蓑羽鹤底下的这片土地还比较平坦

322
00:39:01,630 --> 00:39:05,551
‎那时的土地被挤压
‎并被向上推 形成巨大的褶皱

323
00:39:05,634 --> 00:39:09,638
‎这些褶皱后来形成了
‎地球上最高的山脉

324
00:39:11,724 --> 00:39:12,933
‎也就是喜马拉雅山

325
00:39:19,648 --> 00:39:24,862
‎为了越过山脉
‎蓑羽鹤必须飞到海拔八千米处

326
00:39:27,823 --> 00:39:31,660
‎它们飞得越高
‎周围的氧气含量就越低

327
00:39:40,378 --> 00:39:43,172
‎而精疲力尽的蓑羽鹤
‎若受到袭击 很容易受伤

328
00:39:50,679 --> 00:39:55,351
‎此时 被暖空气托起的金雕
‎从陡峭山坡上飞起

329
00:39:55,976 --> 00:39:58,354
‎在鹤群上方翱翔

330
00:40:12,243 --> 00:40:14,995
‎没多久 金雕突然朝鹤群俯冲飞去

331
00:40:32,012 --> 00:40:34,014
‎为了拿下体型这般巨大的猎物

332
00:40:34,098 --> 00:40:36,058
‎这对金雕协同合作

333
00:40:49,238 --> 00:40:50,823
‎结果这只雏鹤的第一次旅程

334
00:40:52,450 --> 00:40:53,951
‎变成了它的最后一次

335
00:41:10,885 --> 00:41:13,804
‎有比这更低更安全的路线

336
00:41:14,972 --> 00:41:16,849
‎即便如此 鹤的天性

337
00:41:16,932 --> 00:41:20,019
‎就是朝着它们一直以来认定的方向飞

338
00:41:32,031 --> 00:41:34,992
‎直到最近 鹤群遭受了天敌的追捕

339
00:41:35,701 --> 00:41:38,996
‎还损失了许多常去的觅食地点

340
00:41:46,795 --> 00:41:50,633
‎就在这时 印度北部的一个小村庄

341
00:41:51,217 --> 00:41:53,010
‎改写了它们的命运

342
00:42:12,613 --> 00:42:17,785
‎奇倩的村民开始喂养和保护鹤

343
00:42:34,927 --> 00:42:38,180
‎因此 每年冬天越来越多的鹤前来

344
00:42:46,897 --> 00:42:50,734
‎多亏这群鹤的光顾
‎如今奇倩每年有一万五千名游客来访

345
00:42:54,029 --> 00:42:58,075
‎鹤群汇聚成地球上
‎规模最大的鹤类集会

346
00:43:01,412 --> 00:43:02,371
‎对于雏鹤来说

347
00:43:02,454 --> 00:43:06,083
‎它们往南穿越地球上最高山脉的旅程

348
00:43:06,166 --> 00:43:07,585
‎终于告一段落了

349
00:43:08,502 --> 00:43:10,296
‎至少今年可以安定下来了

350
00:43:20,097 --> 00:43:22,099
‎在这个日新月异的世界

351
00:43:22,182 --> 00:43:25,978
‎在迁徙途中的动物
‎比任何时候都需要我们伸出援助之手

352
00:43:29,231 --> 00:43:31,275
‎云南的热带雨林

353
00:43:31,358 --> 00:43:35,988
‎是中国濒危野生象仅存的家园

354
00:43:53,297 --> 00:43:55,132
‎在2020年三月

355
00:43:56,008 --> 00:44:00,888
‎这片森林遭受了有记载以来
‎规模最大、时间最长的干旱

356
00:44:03,265 --> 00:44:04,725
‎树木因此枯死

357
00:44:06,060 --> 00:44:07,978
‎大象也跟着挨饿

358
00:44:15,444 --> 00:44:18,322
‎而新的家庭成员快要出生了…

359
00:44:21,909 --> 00:44:24,745
‎这群大象决定搬走

360
00:44:27,831 --> 00:44:31,001
‎但这趟旅程注定不平凡

361
00:44:33,212 --> 00:44:36,715
‎很快 它们的故事
‎吸引了全世界的注意

362
00:44:39,551 --> 00:44:42,596
‎因为最大的陆地动物

363
00:44:43,806 --> 00:44:45,849
‎在地球上人口最多的国家

364
00:44:47,601 --> 00:44:50,688
‎正找寻落脚的新家

365
00:44:57,361 --> 00:44:59,071
‎它们一家一路往北走

366
00:44:59,154 --> 00:45:03,492
‎走进了一个与离开时截然不同的中国

367
00:45:06,787 --> 00:45:10,582
‎八个月以来
‎它们徒步穿越陌生的新大陆

368
00:45:11,208 --> 00:45:13,419
‎尽管如此 也没能找到任何安身之处

369
00:45:15,087 --> 00:45:19,007
‎因此 它们的新生儿
‎是在迁徙中出生的

370
00:45:22,094 --> 00:45:25,055
‎这对大象来说非常不寻常

371
00:45:27,683 --> 00:45:31,019
‎这样出生的新生儿
‎其生命的起点注定会很疲惫

372
00:45:34,857 --> 00:45:39,486
‎即便如此 现在有17只大象的
‎一大家子不得不继续前行

373
00:45:51,749 --> 00:45:54,918
‎对于那些刚学会走路的小象来说

374
00:45:55,002 --> 00:45:57,129
‎每跨过一处障碍 都困难不已

375
00:46:00,424 --> 00:46:01,717
‎而且每个坡的坡度

376
00:46:02,634 --> 00:46:03,719
‎都很高

377
00:46:11,393 --> 00:46:15,147
‎象群又继续走了四百公里的路

378
00:46:18,233 --> 00:46:20,360
‎一路上 它们越往北跋涉

379
00:46:21,195 --> 00:46:22,905
‎所到之处就越没有归宿感

380
00:46:28,452 --> 00:46:29,828
‎象群为了吃喝

381
00:46:31,497 --> 00:46:33,499
‎被迫偷粮食来填饱肚子

382
00:46:38,587 --> 00:46:40,172
‎但出乎意料的是

383
00:46:41,256 --> 00:46:43,467
‎人们并没有把象群赶走

384
00:46:44,593 --> 00:46:46,887
‎而是它们保驾护航…

385
00:46:48,931 --> 00:46:51,308
‎任其掠夺粮食

386
00:47:01,276 --> 00:47:03,237
‎这群大象迁徙了整整一年后

387
00:47:03,904 --> 00:47:05,489
‎个个筋疲力尽 倒地就睡

388
00:47:13,956 --> 00:47:16,458
‎因为大象通常会站着睡

389
00:47:16,542 --> 00:47:21,171
‎只有当它们特别疲惫之时
‎才会躺下睡

390
00:47:26,885 --> 00:47:29,638
‎如果我们一意孤行
‎不断破坏生态系统 改变我的地球

391
00:47:30,305 --> 00:47:31,890
‎越来越多的动物

392
00:47:31,974 --> 00:47:35,727
‎会被迫踏上这样的新旅程

393
00:47:46,363 --> 00:47:48,991
‎尽管如此 它们的下一次迁徙

394
00:47:50,325 --> 00:47:52,953
‎才是最为特别的

395
00:49:23,377 --> 00:49:26,254
