One extensively trained African grey parrot named Alex became the first non-human animal to pose an existential question when he asked what color he was.

一只名叫亚历克斯的非洲灰鹦鹉经过大量训练后，问出 “我是什么颜色？” 的问题时，成为第一个提出存在性问题的非人类动物。

Over the past several years, the African grey parrots have seen a rise in popularity as pets, largely due to studies that have given us greater insight into the extreme intelligence of these birds.

在过去的几年里，非洲灰鹦鹉作为宠物越来越受欢迎，这主要是因为研究让我们对这些鸟类的极端智慧有了更深入的了解。

Alex, an African grey parrot, combined words to make up new ones: he called an apple a " bannery" , for example, a mixture of banana and cherry (see " The talkative parrot" ).

亚历克斯是一只非洲灰鹦鹉，他把单词组合起来组成了新单词：他把苹果称为“bannery”，例如香蕉和樱桃的混合物（参见“爱说话的鹦鹉”）。

There are even rumors of people who have been fooled into thinking that they were talking to a family member in another room, only to find that it was their pet African grey mimicking another person's voice.

甚至有传言说，有人被骗了，以为他们是在另一个房间里和家人说话，结果却发现是他们的宠物非洲灰猫在模仿另一个人的声音。
