野生虎皮鹦鹉与家养虎皮鹦鹉鸣声比较和声谱分析

Comparison and sound spectrum analysis of the calls of wild budgerigars and domestic budgerigars

为了对比野生虎皮鹦鹉与家养虎皮鹦鹉的鸣声,探究播放野生同类鸣声对家养虎皮鹦鹉鸣叫行为的影响,通过收集和录制虎皮鹦鹉鸣声,使用Cool Edit Pro和Wavesurfer软件对鸣声样本进行处理和数据采集,对各项声学参数进行分析.结果表明,相同生活环境下虎皮鹦鹉的鸣声无明显差异,而不同生活环境下虎皮鹦鹉的鸣声会有一定差异.家养群居个体与独居个体对陌生鸣声的接受程度不同.

In order to compare the calls of wild budgerigars with that of domestic budgerigars,and to explore the influence of playing the calls of wild budgerigars on the singing behavior of domestic budgerigars,by collecting and recording budgerigars’songs,using Cool Edit Pro and Wavesurfer software to process song samples and collect data,various acoustic parameters were analyzed.The results showed that:①there was no significant difference in the budgerigars’calls in the same living environment,while there were some differences in the budgerigars’calls in different living environments.②In domestic budgerigars,solitary and gregarious individuals have different receptivity to unfamiliar homologous calls.
