Darwin's finches of the Galapagos Islands stand as one of the most impressive examples of evolution. After colonizing the islands, a single ancestral finch species eventually diversified into 13 species of different sizes, bill shapes, and ecologies. Imagine if the distribution of that ancestral species was not limited to a small set of islands, but instead had the entire continent of South America in which to diversify! That is exactly what happened with a group of birds known commonly as the ovenbirds and woodcreepers (family Furnariidae). From a single ancestral species, there are now 326 species that differ wildly in body shape and size, feeding behavior, and nest architecture. The primary goal of the project is to use DNA sequences to reconstruct the evolutionary history of all 326 species of ovenbirds and woodcreepers. Over 97% of the ovenbird and woodcreeper species are found within South America so that an evolutionary tree of all 326 species will permit a detailed understanding of the historical processes that led to the impressive radiation.A vital component of this collaborative project between U.S., Brazilian, and Venezulean scientists is the research training it will provide. With fieldwork planned in Bolivia, Brazil, Chile, Colombia, Peru, Suriname, and Venezuela, young scientists from North and South America will be exposed not only to a diversity of natural environments but will also interact and forge relationships with their international peers. By working together to reconstruct perhaps the most spectacular evolutionary radiations of birds in the world, the researchers will learn how evolution works on a continental scale while training a new generation of scientists. This project has been partially supported by the Office of International Science and Engineering at NSF.

达尔文（Darwin）的加拉帕戈斯群岛（Galapagos Islands）的芬奇（Finches）是进化最令人印象深刻的例子之一。 殖民这些岛屿之后，一个祖先的雀科物种最终分为13种不同尺寸，账单形状和生态的物种。 想象一下，如果该祖先物种的分布不仅限于一小部分岛屿，而是使整个南美洲的大陆多样化！ 这正是一群通常被称为烤鸟和木木子（Family Furnariidae）的鸟类。 从单一的祖先物种中，现在有326种在身体形状和大小，喂食行为和巢结构上大不相同。 该项目的主要目的是使用DNA序列重建所有326种烤箱和木木皮的进化历史。 在南美洲，有超过97％的烤箱和木刻物种在所有326种物种的进化树中都可以详细了解导致令人印象深刻的辐射的历史过程。美国，巴西人和委内瑞拉科学家之间的合作项目的重要组成部分将提供其提供的研究培训。 随着在玻利维亚，巴西，智利，哥伦比亚，秘鲁，苏里南和委内瑞拉计划进行的实地调查，来自北美和南美的年轻科学家将不仅暴露于自然环境的多样性，而且还将与国际同行互动并建立关系。 通过共同努力来重建世界上鸟类最壮观的进化辐射，研究人员将在训练新一代科学家时学习进化如何在大陆规模上起作用。该项目已得到NSF国际科学与工程办公室的部分支持。
