通过听觉辨别任务，小组发现鸟类在它们的声乐曲目中区分和分类所有的呼叫类型。此外，在相似行为背景下的呼叫类型之间的系统错误比其声学相似性所能预期的更频繁。它们，斑胸草雀将它们的叫声分类，并对这些声音的含义形成一种心理表征。
据了解，群居动物的声音交流涉及各种叫声的产生和感知，行为学家根据它们的声学结构和行为背景将其分类为不同的叫声类型。这些分类是否对动物有不同的意义仍然未知。斑胸草雀是一种群居鸣禽，有11种不同的叫声，用来传达饥饿、危险或社会冲突，并建立社会联系和纽带。

Abstract: Vocal communication in social animals involves the production and perception of various calls that ethologists categorize into call types based on their acoustical structure and behavioral context. Whether these categories indicate distinct meanings for the animals remains unknown. The zebra finch, a gregarious songbird, uses ~11 call types that are known to communicate hunger, danger, or social conflict and to establish social contact and bonding. Using auditory discrimination tasks, we show that the birds both discriminate and categorize all the call types in their vocal repertoire. In addition, systematic errors were more frequent between call types used in similar behavioral contexts than could be expected from their acoustic similarity. Thus, zebra finches organize their calls into categories and create a mental representation of the meaning of these sounds.
