U.S.-Venezuelan Doctoral Dissertation: Acquisition of Vocal Signatures in Wild Parrots

美国-委内瑞拉博士论文：获取野生鹦鹉的声音特征jack W. Bradbury，康奈尔大学-州立大学该奖项将支持康奈尔大学-州立大学博士生Karl Berg的博士论文研究。本奖项的首席研究员是来自康奈尔州立大学的Jack W. Bradbury博士。这项研究将与委内瑞拉委内瑞拉科学调查研究所的弗吉尼亚·桑兹博士合作完成。桑兹博士是一位著名的鸟类学家，他在幼鹦鹉的传播领域有着专业知识。本研究补充了PI？通过对委内瑞拉绿背鹦鹉进行研究，研究野生鹦鹉的声音学习。该活动将解决两个问题：雏鸟如何获得它们标志性的接触叫声，以及叫声结构的动态变化如何用于配偶之间的“社会谈判”。这项对早期学习阶段的研究可能有助于针对濒危鹦鹉种群的保护计划。

U.S.-Venezuelan Dissertation: Acquisition of Vocal Signatures in Wild Parrots 0825675Jack W. Bradbury, Cornell University-State This award will support dissertation research for Karl Berg, a Ph.D. student at Cornell University-State. The Principal Investigator for this award is Dr. Jack W. Bradbury from Cornell University-State. The research will be done in collaboration with Dr. Virginia Sanz of the Instituto Venezolano de Investigaciones Cientificas, Venezuela. Dr. Sanz is a well known ornithologist who has expertise in the area of dispersal of juvenile parrotlets. The present study complements the PI?s research on vocal learning in wild parrots by incorporating Green-rumped Parrotlets in Venezuela. The proposed activity will address two questions: how do nestlings acquire their signature contact calls, and how are dynamic changes in call structure used in "social negotiation" within mated pairs. This research into the early learning phase could be helpful to conservation programs that target threatened parrot populations.
