摘要
在镜泊湖自然保护区收录黄喉鹀(Emberiza elegans)的鸣唱声,室内作出鸣唱的语图和声谱图。繁殖期黄喉鹀领域鸣唱的频率范围2.4—6KHz,有13—28个音节,2—3个泛音,鸣唱持续时间2.2—4.0秒;具相似的频谱结构,但种内个体间亦存在差异。野外对比实验的结果可说明,黄喉鹀有识别邻鸟和陌生鸟领域鸣唱的能力,有对声音的记忆和定位的能力。
Yellow-throated Buntings' song had been recorded in breeding season. We made out the spectral structure and sound spectrum. The range of song's frequency is about 2.4-6.0KHz, 13-28 syllable and lasting 2.2-4.0 seconds. The sound spectrums are similar but there are some differences in each other. The field experiments show. Yellow-throated Bunting has the ability to recognize the song of neighbors and strangers, and has the ability to memorize, and locate the sound.
