  1. The modulation of sound properties over a wide range of time scales is one of the most obvious characters of oscine passerine ' s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. in oscine passerine, ipsilateral projections of ra to nxiits innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality. as a result, the songs sound well

    鳴禽鳴囀的最大特點之一便是其單次鳴唱時間長，鳴唱所包含的音節數量和音節種類繁多，因而由這些音節所組成的句型結構也是復雜多樣富於變化，且由於nxiits嚴格的側別控制（每一側核團只支配同側鳴肌） ，使其具有更強的控聲能力，其鳴聲音調變化幅度大，頻率高，品質因數大，音色好，因而其鳴聲也悅耳動聽。
