【摘要】 在野外收录繁殖期黄喉鹀的不同鸣声,在室内做出鸣声的语图和声谱图,比较的结果表明:鸣叫声有惊叫声、威胁叫声与应答叫声的区别,它们的频率范围、持续时间和鸣声间隔均有差异。鸣叫声的语图基本形式为间断的柱形,是没有谐音的嗓音语图。鸣唱有求偶、占区等功能。语图的结构复杂,具有相似的频谱结构。但同一个体的鸣唱仍有差异,暗示着鸣唱还有更加复杂的功能。更多还原

【Abstract】 We had recorded the Yellow-throated Bunting’s sound in the field on breeding season and made out the spectral structure and sound spectrum.By comparing it’s shown. The call can be classificated into alarm call,threat call and contact call.There are some differences in the range of frequency,lasting time and interval of calls.The type of call’s spectral structure is the not- continuous volume and the noisy form without overtone. Bird’s song has the function of territory advertisement and mate attra- ction.Song’s spectral structure is very complex and they have similar sound spectrum,But there are some differences in the same individual bird’s song,this implied that the bird’s song must have more complex, function.更多还原
