Music may be one of the oldest forms of art, and its appreciation is thought to be universal among humans. Music could also represent a useful tool to improve captive animals' welfare, especially if individuals can choose the music they prefer. The ability to discriminate between different kinds of music or composers has been demonstrated in numerous non-human species. However, a reinforcing effect of music was found in only a few species, particularly in vocal learner birds such as Passeriformes and Psittaciformes. In this study, we explored whether cockatiels could learn to use a touchscreen to choose between two different pieces of music: first between rock and roll and calm music, and then between consonant and dissonant music. Some birds showed individual preferences for either rock and roll or calm music, but no preferences were found for consonance or dissonance. These results are in line with the hypothesis that vocal learners would be sensitive to music. Our findings offer new prospects for the study of musicality in non-humans and its potential applications for promoting welfare in captive animals: interacting with a touchscreen would allow them to have some control over their environment and to choose their preferred type of music as a form of environmental enrichment.
音乐可能是最古老的艺术形式之一，人们认为人类对音乐的欣赏具有普遍性。音乐也可能是一种改善圈养动物福利的有用工具，特别是如果个体能够选择自己喜欢的音乐。许多非人类物种都已证明具有区分不同类型音乐或作曲家的能力。然而，仅在少数物种中发现了音乐的强化作用，特别是在诸如雀形目和鹦鹉目等能发声学习的鸟类中。在本研究中，我们探究了鸡尾鹦鹉是否能够学会使用触摸屏在两首不同的音乐之间进行选择：首先是在摇滚乐和平静的音乐之间，然后是在和谐音乐和不和谐音乐之间。一些鸟类对摇滚乐或平静的音乐表现出个体偏好，但未发现对和谐或不和谐有偏好。这些结果与发声学习者对音乐敏感的假设一致。我们的研究结果为非人类音乐性的研究及其在促进圈养动物福利方面的潜在应用提供了新的前景：与触摸屏互动将使它们能够对自己的环境有一定的控制，并选择自己喜欢的音乐类型作为一种环境丰富形式。
