Songbirds develop their songs by
The Bengalese finch is a close-ended learner that proimitating songs of adults. For song learning to proceed duces considerably variable songs as an adult. In the normally, the bird's hearing must remain intact present study, we found that Bengalese finches require throughout the song development process. In many real-time auditory feedback for motor control even species, song learning takes place during one period after song learning is complete; deafening adult early in life, and no more new song elements are finches resulted in development of abnormal song synlearned thereafter. In these so-called close-ended tax in as little as 5 days. We also found that there was learners, it has long been assumed that once song deconsiderable individual variation in the degree of velopment is complete, audition is no longer necessary song deterioration after deafening. The neural mechato maintain the motor patterns of full song. However, nisms underlying adult song production in different many of these close-ended learners maintain plasticity species of songbirds may be more diverse than has in overall song organization; the number and the sebeen traditionally considered. ᭧ 1997 John Wiley & Sons, quence of song elements included in a song of an indi-Inc.
