摘 要:采用Avisoft SAS-Lab软件对采自哈尔滨北方森林动物园和扎龙自然保护区的笼养丹顶鹤(Grusjaponensis)和白枕鹤(Grus vipio)的鸣声,即繁殖期对鸣、日常短鸣及幼鸟鸣声进行了语图结构分析,对丹顶鹤和白枕鹤的同源声音进行比较发现,它们的对鸣、日常短鸣及幼鸟的鸣声都具有显著的差异:白枕鹤对鸣的单音节持续时间较丹顶鹤短;丹顶鹤日常短鸣的持续时间较长,频率较高。对于幼鸟鸣声,则是白枕鹤幼鸟鸣声持续的时间更长,频率更高。Acoustic characters of calls, including duet calls, daily calls and calls of infancy of red-crowned crane and whitenaped crane, were studied with Avisoft SAS-Lab. The vocality materials were collected from Harbin North Forest Zoo and Zhalong Nature Reserve. Results showed that there are significant distinctions in sonagrams characteristics between redcrowned crane and white-naped crane. The duration of one syllable in duet of white-naped crane is longer than that of red- crowned crane, while the duration of common call of red-crowned crane is longer and more frequent. The nestling calls of white-naped crane with higher frequency are longer in duration than those of red-crowned crane.
