中文摘要：

2009年5—7月,在辽宁双台河口保护区录制了20只繁殖期斑背大尾莺雄性个体的鸣声。根据行为特征,该鸟鸣声定义为3种鸣声类型：求偶炫耀鸣唱、报警声和联络声。利用Wavesurfer软件对20只斑背大尾莺雄性个体543个鸣声的句子持续时间、句子音节个数、音节持续时间、音节间隔时间等4个参数进行分析测量,发现求偶炫耀鸣唱由节奏逐渐加快的前部句子和音节组成复杂的主体部两个句子组成;报警声和联络声的句子均由单音节组成。音节类型总数为38种,其中包括前部句子的音节类型6种。采用单因素方差分析（one–way ANOVA）对求偶炫耀鸣唱的4个参数进行差异性检验发现,不同个体的各个参数均呈极显著差异（P〈0.01）。

英文摘要：

The songs of Japanese marsh warblers（Megalurus pryeri） were recorded during May to July in 2009 at Shuangtaihekou Nature Reserve,Liaoning,China.Based on song characteristics,songs were divided into three types：courtship songs,alarm calls or contact calls.We analyzed and measured four parameters from 543 verses recorded from 20 males.The parameters were：duration of verse,number of syllables,duration of syllable,and interval of syllable.Verses of courtship song are formed of two verses,the first part＇s rhythm is more and more quick with time;the main body part is formed with complex syllables.Alarm calls and contact calls are simple,and formed with simple and repeat syllables.All songs contained 38 syllable types（six syllable types of the first part included）.Acoustic features of the courtship song were statistically different,as was the calls of each individual.
