摘　　要：2005年2月15日～3月10日使用全方向性麦克风记录了南极地区4种企鹅(王企鹅、长眉企鹅、白眉企鹅和纹颊企鹅)的叫声,分析了其叫声的声谱图和能谱图,比较了不同种企鹅在叫声的持续时间、最高(低)频率和主频等方面的差异。通过比较发现,4种企鹅的叫声存在着明显的种间差异,这使得不同种的企鹅可以从声音上彼此区分开。而无巢企鹅(王企鹅)的声音结构比有巢企鹅(其余3种)更加复杂,这与营无巢生活的习性相符合。In this paper we analyze the calls of four penguin species （Aptenodytes patagonica, Eucl）ptes chrysolophus, Pygoscelis papua, P. antarctica ） recorded in the Antarctic. We analyze the sonogram and power spectrum of the calls and make a comparison among different species in call duration, maximum frequency, minimum frequency and peak frequency. When comparing the temporal and spectral characteristics of their calls we found out that these four species have obvious interspecific variation in the call structure, making it possible for different species to distinguish each other by vocalization. Our results also indicate that the structure of the calls of Aptenodytes patagonica -a non-nesting species, is more complex than that of the other three nesting species.
