摘要
对浙江省嵊泗岛、普陀岛、温岭、长兴、杭州和龙游等６个地区白头鹎的鸣声进行了研究，发现它们鸣声主句的语调、音节数、持续时间、频谱特征和频率范围等均有差异，说明白头鸣鸣声中普遍存在“方言”，但它们作为同一个种在鸣声主句上有其共同特征：主要是鸣声频率多在１．５～３ｋＨｚ的低中频段内变化，单音节的鸣叫声等都极为相似。
The songs of the Chinese Bulbuls in Shensi Island, Putuo Island, Wenting, Changx- ing, Hangzhou and Longyou of Zhejiang Province were studied during the period from Jun. 1993 to Oct. 1994. The results show that song dialects exist in this bird species. The songs of birds from different areas show differences in the tone characteristics, number of sylla- bles, duration, spectral features and frequency range of the main sentence and so on. As a species specificity, however, some basic song characteristics are similar: such as having the same 1.5-3.0kHz frequency range in all the song dialects, and showing high similarity in their monosyllable songs.
