An experimental psychology professor who led the research said that humans are able to distinguish between languages, even ones they don't know, from the intonation and pronunciation, and it seems that paddy birds have the same ability.

领导这次实验的是一位实验心理学教授，他说到，人类能够从语调和发音来辨别不同的语言，即使是一些自己没有掌握的语言也是如此。 现在看来这些以谷类为食的小鸟也具备这种能力。
