Ecological Study on Greenfinch in Lishan Nature Reserve;
历山自然保护区金翅(雀)的生态研究
Greenfinch (Carduelis sinica) produces sound by switching one side of its syrinx to the other is suggested from the fact that unilateral section of tracheosyringeal branch of the hy-poglossal nerve (NXIIts) led to its call phrase being shortened.
单侧切断支配鸣肌的舌下神经气管鸣管亚支(NXIIts)造成金翅(雀)鸣声语句缩短,提示正常状态下金翅(雀)双侧鸣管接替发声;双侧切断NXIIts,导致金翅(雀)伴随呼气发出单音节鸣声,提示失去神经支配的情况下,发声成为完全的被动发声,语图谐波结构显示双侧鸣管吗膜振动引起的发声基本频率不同。
