This research addresses the taxonomic relationships among birds that cache food for future recovery using extraordinary brain capacities for spatial memory. The seed-caching abilities of the titmice (Paridae), nuthatches (Sittidae), and crows/jays (Corvidae) appear to be independent evolutionary acquisitions. Drs. Gill and Sheldon will test the validity of the currently controversial classification of passerine birds by a series of comparisons of the genetic material DNA. In particular, the proposed biochemical analyses will address the historical basis of profound memory capacities of the avian brain and associated changes in feeding and social behavior.

这项研究利用非凡的大脑空间记忆能力，解决了鸟类之间的分类关系，这些鸟类储存食物以供未来恢复。 山雀（Paridae）、五子雀（Sittidae）和乌鸦/松鸦（Corvidae）的种子储存能力似乎是独立进化获得的。 博士。吉尔和谢尔顿将通过一系列遗传物质 DNA 的比较来测试目前有争议的雀形目鸟类分类的有效性。 特别是，所提出的生化分析将解决鸟类大脑的深刻记忆能力以及相关的进食和社会行为变化的历史基础。
