If you're out for a walk and a bird in a tree says to you, "Hello there," don't worry, you're not going mad.

According to Daily Mail, naturalists have reported a growing phenomenon of pet parrots that have been taught to repeat phrases by their owners before escaping from their cages and then passing on the technique to the wild flocks they join.

One scientist said that he had received numerous calls from people who were baffled to hear voices calling to them from trees in their gardens.

"Hello there!" "Hello darling!" and "What's happening?" are among the chorus of comments that flocks of wild birds have been repeating after picking up words and sentences from other birds that were once household pets.

宠物鹦鹉传道授业 野生鸟群齐学舌

       假如你外出散步，突然听到树上有只鸟冲你打招呼：“你好！”别担心，你没有神志不清。

       据英国《每日邮报》报道，许多博物学家表示，主人教会说话的鹦鹉逃脱牢笼后，会把它们的说话技能传授给野生鸟群，这种现象越来越多。

       一位科学家称，他曾接到无数电话，说家中花园里传来鸟说人话的声音，让他们哭笑不得。

       家养的学舌小鸟会教给野生鸟群各种词句，“你好”，“你好，亲爱的”，“什么事？”常被它们挂在嘴边，齐声高唱。
