声音信号是一种常见的交流工具，用于识别不同的个体，宣传生育阶段或区分潜在的配偶。因此，对声音的全面理解构成了研究声音信号在任何动物的性行为和社会行为中的作用的基础。小熊猫（Ailurus fulgens）被列为脆弱物种，在过去的50年里，中国的小熊猫数量减少了40%。已知成年小熊猫在交配和攻击性遭遇时会频繁呼叫;然而，没有人试图对它们的发声进行定量描述。在这里，圈养小熊猫的声音剧目进行了调查。声学和统计分析表明，在繁殖季节7发声类型：“咆哮”，“树皮”，“尖叫”，“咩咩”，“呼”，“咕噜”和“叽叽喳喳”，每种发声类型的声谱图提取。发声的类型随行为状态而变化，并暗示不同的功能背景。未来的研究还需要进一步揭示小熊猫发声在个体识别、性别选择和社会交往中的作用。
Vocal signals are a common communication tool used to recognize different individuals, advertise fertile phases or discriminate amongst potential mates. Therefore, a thorough understanding of vocal repertoires forms the basis for investigating the role of acoustic signaling in the sexual and social behavior of any animal. Red pandas (Ailurus fulgens) are classified as a vulnerable species and have declined by as much as 40% over the past 50 years in China. Adult red pandas are known to call frequently during mating and aggressive encounters; however, no quantitative description of their vocalizations has been attempted. Here, the vocal repertoire of captive red pandas was investigated. Acoustical and statistical analyses indicated seven vocalization types during the breeding season: "growl", "bark", "squeal", "bleat", "hoot", "grunt" and "twitter"; the spectrogram for each vocalization type was extracted. The type of vocalizations produced varied with behavioral state and implies different functional contexts. Future studies are needed to uncover the functions of red panda vocalizations in individual recognition, sexual selection and social interaction.
