Little is understood about the significance of ornaments in species where both sexes are equally ornamented. Using sooty oystercatchers as a model, in a novel integrative approach I will investigate the role of their bright red bill as a signal of mate qualities, as well as the consequences of sex differences in bill and diet. Although sexual diet specialisation is common, few studies have examined its function. Sooty oystercatchers are one of only seven waders to breed in Australia and one of our most visible coastal birds. Since their life history is largely unknown, aside from the academic benefits, this project will also yield valuable information on breeding and foraging requirements of this locally common but declining species.

在两性平等的物种中，装饰物的意义很少被理解。以牡蛎捕手为模型，在一个新的综合方法，我将调查其鲜红的法案作为一个信号的配偶素质的作用，以及法案和饮食的性别差异的后果。虽然性饮食专业化是常见的，但很少有研究探讨其功能。黑蛎鹬是澳大利亚仅有的七种涉禽之一，也是我们最常见的沿海鸟类之一。由于它们的生活史在很大程度上是未知的，除了学术上的好处，这个项目也将产生有价值的信息，繁殖和觅食的要求，这种当地常见的，但下降的物种。
