1
00:00:07,961 --> 00:00:10,591
在哥伦比亚北部的热带丛林中

2
00:00:10,711 --> 00:00:13,720
她和家人住在高高的树上

3
00:00:13,720 --> 00:00:15,530
她叫夏奇拉

4
00:00:15,530 --> 00:00:19,377
一只喜欢喋喋不休的棉顶狨猴

5
00:00:19,557 --> 00:00:21,979
说“哈喽！"

6
00:00:21,979 --> 00:00:23,542
可能你都没注意到

7
00:00:23,542 --> 00:00:24,986
这种一磅左右的小猴子

8
00:00:24,986 --> 00:00:27,751
用一种非常高级复杂的语言交流

9
00:00:27,861 --> 00:00:30,169
由多达38种不同的叫声组成

10
00:00:30,169 --> 00:00:33,743
包含各种啁啾

11
00:00:33,743 --> 00:00:34,887
和哨叫

12
00:00:34,887 --> 00:00:36,893
刚才她给出的回应

13
00:00:36,893 --> 00:00:38,489
被称为“B啁啾”

14
00:00:38,489 --> 00:00:41,182
一种常用来跟人类打招呼的呼叫

15
00:00:41,182 --> 00:00:44,096
为了一感夏奇拉语言的复杂性

16
00:00:44,096 --> 00:00:46,842
让我们先来了解几个啁啾声和哨叫声

17
00:00:47,022 --> 00:00:49,047
之后再看它们的组合

18
00:00:49,117 --> 00:00:51,890
是怎么形成语法结构序列的

19
00:00:52,120 --> 00:00:54,225
夏奇拉用来和我们打招呼的啁啾

20
00:00:54,225 --> 00:00:56,710
是由一组音节组成

21
00:00:56,710 --> 00:00:59,917
被称为单频调制音

22
00:00:59,917 --> 00:01:04,017
这组音节由短音音调，比如啁啾

23
00:01:04,057 --> 00:01:10,717
和长音音调，比如尖叫声，一起组成

24
00:01:10,827 --> 00:01:12,537
研究人员发现

25
00:01:12,687 --> 00:01:14,899
有8中不同的啁啾

26
00:01:15,109 --> 00:01:21,356
是根据升调、音长、峰值频率
和频率变化划分出来的

27
00:01:21,816 --> 00:01:25,008
另外，每一种啁啾有它自己独特的含义

28
00:01:25,418 --> 00:01:29,757
比如说，当夏奇拉的“C啁啾”

29
00:01:29,757 --> 00:01:31,822
会用在她获取食物的时候

30
00:01:31,882 --> 00:01:35,370
而“D啁啾”

31
00:01:35,370 --> 00:01:38,481
只有在她手中有食物时才会使用

32
00:01:38,771 --> 00:01:42,917
单信号哨叫
也在每次呼叫中表达独特的意思

33
00:01:42,917 --> 00:01:45,315
就如存在着8种不同的啁啾

34
00:01:45,375 --> 00:01:46,996
哨叫也有5种之分

35
00:01:47,106 --> 00:01:49,328
根据频率调制

36
00:01:49,328 --> 00:01:52,567
哨叫也被细分成4个子类：

37
00:01:52,876 --> 00:01:56,093
吱吱声

38
00:01:56,113 --> 00:01:59,381
初始调制哨叫

39
00:01:59,381 --> 00:02:03,229
终极调制哨叫

40
00:02:03,229 --> 00:02:05,178
以及平哨

41
00:02:05,208 --> 00:02:07,359
这种语言表达含义时的清晰性

42
00:02:07,553 --> 00:02:12,163
完全可以用初始调制哨叫的种类来说明

43
00:02:12,183 --> 00:02:14,645
这些哨叫会根据夏奇拉

44
00:02:14,775 --> 00:02:17,724
与她家人之间的距离远近而改变

45
00:02:17,954 --> 00:02:20,948
如果夏奇拉与她家人之间的距离
远于 0.6 米

46
00:02:21,178 --> 00:02:25,768
她就会发出高度初始调制哨叫

47
00:02:25,918 --> 00:02:28,123
但如果她与家人的距离小于 0.6 米

48
00:02:28,373 --> 00:02:32,781
她就会发出轻度初始调制哨叫

49
00:02:32,781 --> 00:02:35,069
现在我们既然已经了解了几种
啁啾和哨叫

50
00:02:35,069 --> 00:02:37,309
夏奇拉灰常想跟你炫耀一下
她的语言功底

51
00:02:37,469 --> 00:02:40,524
她要带你体验一下
她从早到晚所发出的声音

52
00:02:40,534 --> 00:02:43,966
当她跳到一棵书上开始她的早餐时

53
00:02:44,076 --> 00:02:46,611
她说，(猴子的叫声)

54
00:02:46,611 --> 00:02:50,353
这是一种多用于放松的探查的叫声

55
00:02:50,363 --> 00:02:54,009
然而，她突然发觉一直大鹰的影子

56
00:02:54,029 --> 00:02:56,949
她发出报警声“E啁啾"

57
00:02:57,039 --> 00:03:00,102
这声音警示她家人：捕食者靠近了！

58
00:03:00,362 --> 00:03:03,131
夏奇拉自己也赶紧跳入
密枝深处的安全地带

59
00:03:03,241 --> 00:03:05,141
现在该没事了

60
00:03:05,141 --> 00:03:07,561
所以夏奇拉向她的爸爸靠近

61
00:03:07,751 --> 00:03:09,289
等等，等等，那个小家伙是谁？

62
00:03:09,429 --> 00:03:11,650
啊哈，是她的弟弟卡洛斯

63
00:03:11,710 --> 00:03:16,002
棉顶狨猴玩摔跤的时候通常会发出尖叫

64
00:03:16,562 --> 00:03:21,003
啊哦，卡洛斯有点粗暴了
夏奇拉开始尖叫

65
00:03:21,243 --> 00:03:23,368
想让她父母来帮她

66
00:03:23,478 --> 00:03:26,396
她爸爸朝着扭打成一团毛球走去

67
00:03:26,466 --> 00:03:28,036
她弟弟识相地停了下来

68
00:03:28,036 --> 00:03:29,219
夏奇拉抖了抖身子

69
00:03:29,219 --> 00:03:31,210
伸手捋了捋她头上的毛

70
00:03:31,210 --> 00:03:33,055
恢复她的发型

71
00:03:33,245 --> 00:03:36,714
之后，夏奇拉发现了另一群
不太熟悉的棉顶狨猴

72
00:03:36,884 --> 00:03:39,205
听了听它们的长叫

73
00:03:39,585 --> 00:03:42,981
她转向她的家人(猴子叫声)

74
00:03:43,161 --> 00:03:46,929
你听出来了吗？首先是个啁啾
然后是个哨叫

75
00:03:46,929 --> 00:03:49,844
这被称为组合发声

76
00:03:50,074 --> 00:03:53,628
一个由一声啁啾和一声哨叫组成的“短语”

77
00:03:53,758 --> 00:03:57,339
这两声串起来表达一条信息

78
00:03:57,419 --> 00:03:59,802
她把这两个声音元素合在一起

79
00:03:59,802 --> 00:04:02,415
通知她的家人另一个群体存在
她用“F啁啾”

80
00:04:02,565 --> 00:04:05,794
并同时说明这个群体与他们的距离

81
00:04:05,964 --> 00:04:07,666
她用惯用的长口哨

82
00:04:07,826 --> 00:04:10,533
换句话说，夏奇拉刚刚说了句话

83
00:04:10,853 --> 00:04:14,280
她这句简单的话只是它们语言的冰山一角

84
00:04:14,370 --> 00:04:18,595
她还有有颤音，饶舌，多样的哨叫

85
00:04:18,825 --> 00:04:22,710
更有多种组合发音，甚至有吱吱喳喳

86
00:04:23,390 --> 00:04:26,060
然而，让人难过的是，我们可能永远也听不尽

87
00:04:26,060 --> 00:04:27,684
她说得每一件事

88
00:04:27,834 --> 00:04:30,729
伴随树木高处啁啾的

89
00:04:30,989 --> 00:04:34,297
还有持续不断的砍伐树木的轰隆声

90
00:04:34,925 --> 00:04:37,126
夏奇拉在哥伦比亚的家正在被砍伐

91
00:04:37,326 --> 00:04:38,944
一棵又一棵的树倒下

92
00:04:39,344 --> 00:04:40,851
如果我们不采取行动

93
00:04:40,911 --> 00:04:42,969
保护濒临灭绝的棉顶狨猴

94
00:04:43,329 --> 00:04:45,589
它们会在我们有生之年绝迹的

95
00:04:46,019 --> 00:04:48,830
如果棉顶狨猴之间的啁啾

96
00:04:48,960 --> 00:04:50,903
被证明不仅仅是闲聊那么简单

97
00:04:51,023 --> 00:04:53,354
想象一下还有多少是我们有待发现的

98
00:04:53,464 --> 00:04:55,844
想象一下夏奇拉还告诉了我们什么
