摘　　要：利用计算机鸣声分析技术对白头鹎（Ｐｙｃｎｏｎｏｔｕｓ　ｓｉｎｅｎｓｉｓ）繁殖期的求偶炫耀鸣唱、晨鸣、遇险告警和惊叫等鸣声的特征进行分析，以探讨鸣声特征与行为的关系。白头鹎繁殖前期特有的求偶炫耀鸣唱婉啭多变，频率一般变化在１．９～３．５ｋＨｚ之间；另一类出现在繁殖前、中期的炫耀鸣唱急促而响亮，音节变化快且频率高（变化范围约３．４～４．４ｋＨｚ）；晨鸣和繁殖期特有的其它鸣声，音节清晰，响度较大，能量主要集中在２～３ｋＨｚ之间，可能具有宣告领域的归属和保卫作用；告警鸣声以频带很宽为其特点，约在１～４．５ｋＨｚ之间；幼鸟惊叫声的频率高，有２个峰值频率，基本声的ＭＰＦ约在４．２ｋＨｚ。Characteristics of Chinese bulbul (Pycnonotus sinensis) songs, including courtship song, mating song, morning song. alarm call and frightening call, and the relationship between the characteristics of songs and the behavior in the breeding season were studied with computer analysis in this paper. The result shows that the courtship song, occuring in the early period of breeding season, was a kind of sweet and changeable singing, and the frequency was between 1.9 3.5 kHz. In the early and middle period of breeding season, the mating song (frequency was between 3.4-4.4kHz) could often be heard, and the mating song was short and loud. The morning song and some other songs , occurring only in breeding season, were related to the definiton and defence of their territory. These songs had clear and loud syllables. The energy of these songs was mainly distributed in the frequency range between 2-3kHz. The alarm call showed broad range of frequency between 1-4.5kHz. The frequency of the frightening call of the young was high, and its MPF was about 4. 2kHz.
