虎皮鹦鹉有一个复杂的声乐曲目,其中一些是通过学习发展的。作者研究了虎皮鹦鹉从孵化到大约4周后(大约85天)的声音发育过程。乞讨食物的电话显示的变化,持续时间,峰值频率,带宽和频率调制与年龄。在一个星期的羽翼,每只鸟产生了一个接触呼吁轴承非常相似的一个缩短版本的模式的食物乞讨呼吁。由4周postfulling,虎皮鹦鹉接触呼叫剧目往往包含一个以上的呼叫类型,并有明确的证据共享和模仿父母,幼鸟,和其他社会同伴之间的呼叫。知觉测试表明,而声学变化的结构发展中的调用内和雏鸟之间的下降,这些电话的歧视是更容易为成年鸟幼鸟成熟。这些结果与人类语言发展的某些方面相似。(PsycINFO数据库记录(c)2016阿帕,保留所有权利)
Budgerigars have a complex vocal repertoire, some of which develops through learning. The authors examined the course of vocal development in budgerigars from hatching to about 4 weeks postfledging (approximately 85 days old). Food-begging calls showed changes in duration, peak frequency, bandwidth, and frequency modulation with age. Within a week of fledging, each bird produced a contact call bearing a strong resemblance to a shortened version of its patterned food-begging call. By 4 weeks postfledging, budgerigar contact call repertoires often contained more than one call type, and there was clear evidence of sharing and imitation among the calls of parents, fledglings, and other social companions. Perceptual testing showed that whereas acoustic variation in the structure of developing calls decreased both within and between nestling birds, the discrimination of these calls was easier for adult birds as young birds matured. These results suggest parallels with certain aspects of language development in humans.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
