These results open up a new knowledge for comprehensive analyses of abnormalities of acoustic behavior habits in budgerigars prior to earthquakes. Under indoor lighting, the song calls in budgerigars are possessed of the beginning and ending singing time with the natural characteristics, and of the rhythmic habit of daylight singings and night rests. In daily daylight and night calls, single calls, van-toned calls, mono-syllabic and multi-syllabic protest calls are respectively possessed of the occupation habit corresponding to behavior activities, and have close acrophases and regular following properties corresponding to half-value phases, and the acrophases delay halfvalue phases by about half an hour on an average. After reversing lighting, the acrophases of budgerigar calls delay those of the normal lighting by about 12 hours on an average, and the following properties corresponding to half-value phases are irregular.展开更多
