内容 (Contents): ピ・ピ・ピ・・・ケキョ・ケキョ・ホーホケキョ。前鳴きから、ケキョ、ケキョ、ホーホケキョ、まで(背景にカラスの声入り) 若い鳥は最初からホーホケキョと上手に鳴くことができない。周囲の鳴き声を真似しながら徐々にホーホケキョと鳴くことができるようになる。カラスの鳴き声も聞こえる。 (Pi pi pi... kekyo kekyo Hooo- hoke'kyo hooo- hokekyo) A young bird can't sing well with "hoo hokekyo" from the beginning. It learns to sing gradually with "hoo hokekyo" with imitating surrounding song. Corvus Macrorhinus can be heard in the background.
