9909989HombergerThis award supports a US-Australia collaborative research program aimed at elucidating the function and evolution of feeding mechanisms in Red-tailed Black Cockatoos. The investigator proposes to describe the range of feeding mechanisms used by different species, subspecies, populations or morphs (the taxonomic designation of which is in flux), and to relate those mechanisms functionally to diet, and thus to gain insight into the evolution of the extreme variation in bill morphology present in this group. She proposes to accomplish this by observation of feeding birds in the wild, collection and analysis of debris from feeding events, and dissection and anatomical analysis of the beaks of specimens. The PI is recognized world-wide as an authority on the functional anatomy of the beak and tongue in psittaciform birds and is very well qualified to investigate the range of variation present in the anatomy of these very variable birds. A better understanding of the feeding and feeding structures of these animals is also very desirable given that they are simultaneously threatened by the international trade in parrots, while functioning to some degree as crop pests at home. The research will be conducted in partnership with colleagues in Australia, including researchers at the Australian National University, the CSIRO Division of Wildlife and Ecology, and Queensland University of Technology.

9909989 Homberg该奖项支持美国-澳大利亚合作研究计划，旨在阐明红尾黑凤头鹦鹉的功能和进食机制的演变。研究者建议描述不同物种、亚种、种群或变体（其分类学名称正在变化）使用的摄食机制的范围，并将这些机制与饮食功能联系起来，从而深入了解该组中存在的喙形态极端变化的演变。她建议通过观察野外觅食的鸟类，收集和分析觅食事件的碎片，以及解剖和解剖分析标本的喙来实现这一目标。该PI在全球范围内被公认为鹦鹉螺类鸟类喙和舌功能解剖学的权威，并且非常有资格研究这些变异鸟类解剖学中存在的变异范围。 更好地了解这些动物的喂养和喂养结构也是非常可取的，因为它们同时受到鹦鹉国际贸易的威胁，同时在某种程度上作为国内作物害虫。 这项研究将与澳大利亚的同事合作进行，包括澳大利亚国立大学、CSIRO野生动物和生态部以及昆士兰州科技大学的研究人员。
