鸟类鸣叫是鸟类行为研究的一项重要内容，为探究纯色山鹪莺（Prinia inornata）的鸣叫模式与其尾羽逆向变化的关系，于2007年8－10月在广东省肇庆江溪村对繁殖期纯色山鹪莺的领域鸣声等行为进行研究。运用焦点动物观察法，通过Olympus DS-20数码录音笔（100—17 100 Hz）和直径50 cm声音收集器采集声音。行为统计以直接观察和Sony DCR-VX2000E数码摄像机录像相结合。结果如下：⑴共采集到620个鸣句，分属6种鸣句类型，其中4中为常见类型，1种为过渡类型，1种少见类型。（2）纯色山鹪莺的鸣声结构简单，变化较多，能够根据环境改变鸣声，具有识别危险程度和危险对象种类的能力。（3）鸣声均和一定的行为具有联系，4种主要鸣声类型均伴有抖尾行为出现。据此认为，纯色山鹪莺鸣唱结构简单但变化较多，而尾羽在其领域鸣叫行为中发挥了一定作用。
Bird song is an important way of studying bird behavior in the field. To understand the relationship between songs and tail action of Plain Prinia（Prinia inornata），we studied their territorial songs during August and October in 2007 in Jiangxi Village of Zhaoqing，Guangdong. The results showed: 1) Plain Prinia had six song types，four were frequent, one transitional and one scarce type. 2) The song was simple but its type varied，indicating different types and degrees of danger. 3) The four song types had connections with different behaviors，and each song was accompanied by tail shaking. Therefore，we concluded that the structure of the songs was simple but varied a lot，and tail action had a function in these territorial songs.
