摘要
以成年雌性牡丹鹦鹉(Psittacula agapornis)为实验材料,用mp3采集声音、记录,Cool edit2000和wave-surfer软件对牡丹鹦鹉声音进行分析.结果表明,各种类型鸣声的频域特征基本一致,说明牡丹鹦鹉的叫声处于比较稳定的状态.主频在不同鸣叫类型中各有差异,单鸣声相对幅值最小.探讨了牡丹鹦鹉各类鸣声在时域和频域方面的差异,为有关亚鸣禽类鸣叫特征及其行为方面的研究提供资料.
This experiment were made with adult female Psittacula agapornis,using mp3 to record calls,cool edit2000 and wavesurfer to analyze the sounds.The results showed that the frequency feature of different call types have no differences,adult birds vocalization are in stable state.The PF is higher in multi-call,and the RA is lower in single-call.By comparing the differences of different calls in time domain（TD） and frequency domain（FD）,and this study will provide some evidences for calls characters,rhythms and behaviors in birds.
