| 摘 要： | 利用叫声回放和声谱分析对莲花山自然保护区鬼甘肃亚种(Aegolius funereus beickianus)繁殖期的叫声进行了研究。共记录了领域叫声、尖叫声等6种叫声,分析了各种叫声的特征及与行为的联系。发现不同地点录制的领域叫声存在差异,但同一个体的叫声也有变化。甘肃亚种的领域叫声和欧洲的指名亚种A.f.fu-nereus及北美的亚种A.f.richardsoni相比较,单音数量少,单音长度小,频率高,但差异不大。

| Abstract: | Vocalizations of the boreal owl(Aegolius funereus beickianus)in Lianhuashan Nature Reserve were recorded and analyzed in breeding season of 2004.Six calls were identified,including primary call,MooA call and Skiew call of males;weak call of females;chirp and chatter calls of nestlings.The characteristics of each call were summarized.There are differences between some primary calls from different recording sites,but the calls of the same individual also show some variances.Compare to A.f.funereus and A.f.richardsoni in other regions,the primary call of A.f.beickianus has shorter,fewer notes and higher frequency,however,no essential differences. |
