崖沙燕繁殖期雄鸟的鸣叫行为

Vocal Behaviors of Male Sand Martin (Riparia riparia) in Breeding Season

2003年3月～2004年4月在南充市郊的嘉陵江边记录了崖沙燕(Ripariariparia)繁殖期雄鸟的鸣叫。声谱分析结果表明,崖沙燕繁殖期有8种鸣叫(恫吓叫声、屈服叫声、求救叫声、警报叫声以及4种鸣唱声)。通过对其行为的实时观察,确定了每种鸣叫的生物学意义。4种叫声是整个繁殖期的主要鸣叫,而4种鸣唱声则主要出现在开春以后的集群求偶与筑巢期间。虽其鸣唱声仅有两种类型的短音节,但通过组合可形成含有多达4个或6个音节的鸣唱声。鸣唱声的持续时间分别为3184、1030、1274、1232ms。鸣唱声中的间歇时间分别占持续时间的47%、39%、50%、48%。

Eight different sounds (threatening call, submitting call, distress call, alarm call and four kinds of song) were recorded in Nanchong, Sichuan Province, in Sand Martin’s (Riparia riparia) breeding season from March 2003 to April 2004. The characters of the calls were analyzed by computer technique. Biological meaning of every kind of call was determined, by observing on behaviors of Sand Martin. The four kinds of single calls were mostly frequent during the breeding season. The four kinds of song were heard, when Sand Martins pairing and nesting since early spring. Spectrographic analysis showed that there were only two kinds of short syllables in songs, but they made up sentences, which had four or six syllables,by assembling and arranging. The total durations of singing were 3?184 , 1?030, 1?274,1?232?ms, the off times of them took 47%, 39%, 50%, and 48% respectively.
