Neotropical grassland birds are intimately tied to their habitat and form a phylogenetically diverse group that has been poorly studied from an evolutionary point of view. Here we present a brief review of the biogeographical history of Neotropical grasslands of relevance to grassland birds. Based on this review, we have formulated the most relevant hypotheses related to the diversification and evolution of Neotropical grassland birds. Several of the hypotheses tested are complementary to those that can be tested for forest birds and may offer the researcher fruitful foci of study for assessing the role of South American geological evolution in shaping the diversification of the world’s most diverse avifauna.

评估新热带地区草地鸟类进化的一般方案

新热带草原鸟类与它们的栖息地紧密相连，形成了一个系统进化上多样化的群体，从进化的角度来看，这些群体尚未得到很好的研究。在此，我们简要介绍与鸟类鸟类有关的新热带草原的生物地理历史。在此基础上，我们提出了与新热带草原鸟类的多样性和进化有关的最相关的假设。所检验的几种假设与可以对森林鸟类进行检验的假设是互补的，并且可以为研究人员提供丰富的研究重点，以评估南美地质演化在塑造世界上最多样化的航空动物多样性方面的作用。
