THE WHISTLES OF WILD BOTTLENOSE DOLPHINS OFF TSUJI ISLAND AND CAPTURED ONES IN AQUARIUM WERE RECORDED AND ANALAYZED. THE SIGNATURE WHISTLES FROM THE SAME INDIVIDUAL ARE NOT ALWAYS SAME AND THERE ARE SOME VARIATIONS IN TIME AND FREQUENCY, ESPECIALLY IN TIME. 251 KINDS OF THE SIGNATURE WHISTLES WERE RECOGNIZED FROM THE DATA OF 4 YEARS AND 231 KINDS OF THAT WERE RECOGNIZED IN 1999. THIS IS MEANING THAT MANY OF THE SAME SIGNATUTE WHISTLE ARE BEING UTLIZED FOR LONG TIME. AMONG THE WHISTLES, A RATIO CONTAINING SIGNATURE WHISTLE WAS VERY HIGH ( MORE THAN 90%).15 PARTICULAR COMBINATIONS OF SIGNATURE WHISTLES WERE OBSERVED AND 5 AMONG OF THEM WERE OBSERVED IN DIFFERENT PLURAL DAYS, MONTHS OR YEARS. MOREOVER, SOME PECULIAR SIGNATURE WHISTLES WERE ALSO OBSERVED DURING THE WHISTLE EMITTING BETWEEN THOSE PARTICULAR COMBINATIONS. IT SEEMS THAT SIGNATURE WHISTLES HEARD IN THE SAME RECORDED TIME ARE SHOWING THE WHISTLES FROM INDIVIDUALS IN THE SAME SMALL GROUP (FAMILY ?). NUMBERS OF SIGNATURE WHISTLE TYPES CONCERNED WITH ONE GROUP WERE LESS THAN 8.

记录和分析了筑岛附近野生宽吻海豚和水族馆捕获的宽吻海豚的鸣叫声。来自同一个人的标志性口哨并不总是相同的，在时间和频率上有一些变化，特别是在时间上。从4年的数据中识别出251种特征哨声，1999年识别出231种特征哨声。这意味着许多相同的SIGNATUTE哨子被使用了很长时间。在哨声中，含有特征哨声的比例很高(超过90%)。观察到15种特殊的特征哨声组合，其中5种出现在不同的复数日、月或年。此外，在这些特定组合之间发出的哨声中还观察到了一些特殊的特征哨声。似乎在同一记录时间内听到的标志性口哨声显示的是同一小组(家庭？)中的个人发出的口哨声。同一组涉及的签名哨声类型数不到8个。
