养鸟的行家都知道,鸣禽的雄性幼雏向老鸟学习本种鸟的鸣叫.把雄雏与鸣声隔离,用鸣叫声的录音带教它们,则幼鸟学习鸣叫仅限于一定的期间,并且有遗传性,即幼鸟似乎只学习本种或与本种非常相似的叫声.如果不用录音带而是鸟直接教幼鸟鸣叫,幼鸟可以看到老鸟打交道,这样,不但学习期限大为延长,而且幼鸟还愿学其他种鸟的叫声.这说明社会交往对幼鸟学叫期的长短及学习的天性都很重要.但究竟社会交往中什么是重要的,仍不得而知.
Avaricers know that young male songbirds learn the tweet of the bird from the old bird, isolate the male from the song, and teach them with the ringing tapes, and the tweet of the young bird is limited to a certain period of time, and Hereditary, that young birds seem to learn only this species or very similar to this call .If the tape without the birds directly teach the tweet, the young bird can see the bird dealing with, so that not only learning period is large , And the young birds are also willing to learn the voices of other species of birds.This shows that social interaction is important for both young and old learning and the nature of learning.But what is important in social interaction is still unknown.
