  • The sound spectrograph of mandarin vole in different age groups and behavioural states were analysed in order to study the regular pattern of the songs development and the relationship between the characters of calling songs and relative behaviours.Sonograms of juveniles were simple and the MPF (main peak frequency) was about 1800 Hz.There was one energy range located in medium frequency range (1300-2500 Hz).The sonograms of sub-adults were more complicated than those of juveniles and there were two energy ranges which both were located in medium frequency range (750-1302 Hz,1431-1570 Hz),MPF=945 Hz.The frequency spectrums of calling songs of adults were the most complicated and had several energy peaks.Although there was great difference in different conditions,two energy ranges were generally located in adults.One was located in medium frequency range (550-4127 Hz) and the other was located in high frequency range (5500- 8125 Hz).The calls of different individuals in different behavioural states had different biological meanings.
