摘要

蛇的听觉系统和声音动力学经常是争论的对象。已知的蛇发出声音的频率在0.2到9.5千赫之间。在这里，我们报告了南美洲蛇Dipsas catesbyi发出声音的第一个记录。该呼叫是在2021年6月通过操纵偶然录制的，持续时间为0.06秒，峰值频率达到3036赫兹，通过喉部呼出空气发出调制音符。我们假设，像这样有结构的声音释放是对捕食企图的反应，可能是其他种类的双翅蛇和其他蛇的共同特征。

First record of a snake call in South America: the unusual sound of an ornate snail-eater Dipsas catesbyi

ABSTRACT The auditory systems and sound dynamics in snakes are frequent objects of debate. The known frequency of sounds produced by snakes ranges from 0.2 to 9.5 kHz. Here we report the first record of a vocalization by the South American snake Dipsas catesbyi. The call was recorded oportunistically in June 2021 upon manipulation, and had a duration of 0.06 seconds, reaching 3036 Hz in its peak frequency with a modulated note, emitted through exhalation of air through the larynx. We hypothesize that structured vocal emissions such as this are a reaction to a predation attempt and may be a feature shared by other species of Dipsadidae and other snakes.
