摘要
黑头噪鸦(Perisoreusinternigrans)是我国青藏高原高山针叶林的特有鸟类,由于分布海拔高、数量稀少,因此对于黑头噪鸦的研究非常少。本文对2 0 0 0年3月～2 0 0 3年6月在甘肃和四川录制的黑头噪鸦的8种叫声进行了描述及声谱分析。结合野外观察,分析了黑头噪鸦的叫声及其行为联系。黑头噪鸦的乞食叫声可能在整个繁殖生活史中具有重要意义。研究中未发现黑头噪鸦对录音回放产生回应。
The Sichuan Jay (Perisoreus internigrans)is an endangered species endemic to the high mountain conifer forest in western China. Because of its occurrence in high elevation and its low population level,there has been little research report on this species.In this paper, we described the calls of the Sichuan Jay collected from Sichuan and Gansu during Mar. 2000 to Jun. 2003. Eight types of calls were digitalized and frequency spectrograms were given. Begging calls were recorded in various breeding stages and considered to be a key vocal behavior in its life history. No response can be found during play back experiment.
