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.

生活在加拉帕戈斯群岛的达尔文雀是进化史上最令人印象深刻的例子之一。 在殖民岛屿后，一个单一的祖先雀物种最终多样化成13个不同大小，喙形状和生态的物种。 想象一下，如果这种祖先物种的分布不仅限于一小部分岛屿，而是整个南美洲大陆的多样化！ 这正是发生在一群鸟身上的事情，这些鸟通常被称为烤箱鸟和啄木鸟（科）。 从一个单一的祖先物种，现在有326个物种，在身体形状和大小，进食行为和巢穴建筑方面存在很大差异。 该项目的主要目标是利用DNA序列重建所有326种烤箱鸟和啄木鸟的进化历史。 超过97%的烤箱鸟和啄木鸟物种在南美洲被发现，因此所有326个物种的进化树将允许详细了解导致令人印象深刻的辐射的历史过程。巴西和委内瑞拉的科学家是它将提供的研究培训。 计划在玻利维亚、巴西、智利、哥伦比亚、秘鲁、苏里南和委内瑞拉进行实地考察，来自北美洲和南美洲的青年科学家不仅将接触到各种各样的自然环境，而且还将与国际同行进行互动并建立关系。 通过共同努力重建可能是世界上最壮观的鸟类进化辐射，研究人员将了解进化如何在大陆范围内运作，同时培训新一代科学家。该项目得到了NSF国际科学与工程办公室的部分支持。
