在成年棕头燕八哥（Molothrus ater ater）的歌曲生产是偏侧的，轻微的右舌优势。塞林克斯的左侧产生低频（200-2000 Hz）音符，而右侧产生高频（1500-6000 Hz）的介绍性音符，相间单位（10-12 kHz）和最后的高频哨声（5-13 kHz）。交叉相关分析显示，燕八哥个体的四到七种鸣叫类型中的每一种都有一种独特的刻板的运动模式，这是通过舌下气流和舌下压力的模式来判断的。不同歌曲类型的声学差异反映在与歌曲产生相关的支气管气流和空气秒压力模式的差异中。这些运动差异在第二和第三个介绍性音符群中特别引人注目，在这些音符群中，在产生音符的过程中，鸣管的两侧之间存在快速的来回切换。这些运动技能在产生行为上有效的歌曲中可能特别重要。(C)1994年，John Wiley and Sons，Inc.
Song production in adult brown-headed cowbirds (Molothrus ater ater) is lateralized, with a slight right syringeal dominance. The left side of the syrinx produces low-frequency( 200-2000 Hz) notes within the introductory note clusters, while the right side produces the higher-frequency (1500-6000 Hz) introductory notes, the interphrase unit (10-12 kHz), and the final high-frequency whistle (5-13 kHz). Cross-correlation analyses reveal that individual cowbirds produce each of their four to seven song types with a distinct stereotyped motor pattern-as judged by the patterns of syringeal airflow and subsyringeal pressure. The acoustic differences across song types are reflected in the differences in the bronchial airflow and air sec pressure patterns associated with song production. These motor differences are particularly striking within the second and third introductory note clusters where there is a rapid switching back and forth between the two sides of the syrinx in the production of notes. These motor skills may be especially important in producing behaviorally effective song. (C) 1994 John Wiley and Sons, Inc.
