白色-眼睛是一个标志性的鸟类辐射的小雀形目，主要分布在东半球的热带和亚热带地区。白色眼睛的物种多样性在海洋岛屿上特别高，许多物种仅限于单个岛屿或岛屿群。白色眼睛的物种多样性高，使它们成为鸟类中已知的辐射最快的物种之一，但它们加速的多样性是否是反复殖民岛屿的结果仍然没有被探索。我们使用了一个新的估计，几乎所有的zosteropids和系统发育比较方法，估计和比较岛屿和大陆血统之间的多样化率。我们发现，岛屿白色眼睛有类似的灭绝率，但更高的物种形成率相比，大陆白色眼睛。此外，我们发现从岛屿到大陆的过渡率更高。我们的研究结果显示了岛屿的重要性，例如印度太平洋的Wallacean和Melanesian群岛，在促进这一显着分支内的高物种形成率方面。
White‐eyes are an iconic avian radiation of small passerines that are mainly distributed across the eastern hemisphere tropics and subtropics. Species diversity of white‐eyes is particularly high on oceanic islands, and many species are restricted to single islands or island groups. The high rate of species diversification of white‐eyes ranks them among the fastest radiations known in birds, but whether their accelerated diversification was the result of repeatedly colonizing islands remains unexplored. We used a newly estimated timetree for nearly all zosteropids and phylogenetic comparative methods to estimate and compare diversification rates between island and continental lineages. We show that island white‐eyes have similar extinction rates, yet higher speciation rates compared with continental white‐eyes. In addition, we find higher rates of transitions from islands to continents. Our results show the importance of islands, such as Wallacean and Melanesian archipelagos of the Indo‐Pacific, in facilitating high rates of speciation within this remarkable clade.
