虎皮鹦鹉（Melopsittacus　undelafus）的声行为习性及其微机分析

THE HABITS OF ACOUSTIC BEHAVIOR IN BUDGERIGAR (Melopsittacus undelafus) AND MICROCOMPUTER ANAL YSIS

本文对自然条件下虎皮鹦鹉（ＢＧ）声行为观测资料，进行了微机分析。所得到的ＢＧ声行为特性很好地反映相应的自然习性。这就为地震生物观测站（ＳＢＯＳ）的ＢＧ声行为与地震关系观测资料的微机分析提供了基本方法，进而提高了动物习性异常在临震预报中的有效性。所得到的ＢＧ始鸣时和终鸣时，分别与观测站的日出和日没时呈正相关，变化速率都为０．９，即很好地反映ＢＧ声行为昼夜节律的季节变化习性。所得到的ＢＧ单次叫声（ＳＣ）、变音调叫声（ＶＴＣ）、单音节和多音节抗议叫声（ＭｏＳＰＣ和ＭｕＳＰＣ）的占有率，很好地反映出所表征的行为活动和相应的自然习性，并可看到ＢＧ不同声行为叫声的相互之间关系，及其与天气变化的关系。所得到总叫声峰相位具有明显的季节变化，与始鸣时呈负相关，而与终鸣时呈正相关。同时，不同叫声与总叫声的峰相位具有一定的跟随关系，反映出每天的叫声算术平均值的时间位置特性。

The microcomputer analysis of observation data of acoustic behavior of budgeriga (BG) under natural conditions is made in this paper. Obtained characteristics of acoustic behavior of BG reflect correspondinao natural habits very well. Now, it's possible to provide a basic method of microcomputer analysis of observation data of the relationship between acoustic behavion of BG at seismobiological observation station and earthquake, and then effectiveness of impending earthquake prediction by animal abnormal habits will be raised. The beginning and ending times of BG calls each day and night present positive correlations with the sunrise and sunset time at the station respectively, and both the variation rates are 0.9, reflecting seasonal change habits of day and night rhythms of acoustic behavior of BG very well. The occupation rates of singl call, varitoned call mono-syllabic and multi-syllabic calls of BG reflect characterized behavior activities and corresponding natural habits quite well. Moreover, The interrelation among different calls of acoustic behavior of BG and their relation with weather change also are found. The acrophases of total calls show obviously seasonal change, which present the negative correlation with the beginning time and the positive correlation with the eanding time. Moreover, the acrophases of different and total calls present cetain relations and reflect the time-location characteristics of arithmetic means of different calls on each day and night.
