雀形目鸟类（Passeriformes）的巢的建筑多样性被认为在这一群体的适应性辐射中发挥了重要作用，这一群体现在包括一半以上的鸟类物种，并占据了几乎所有的陆地生态系统。在这里，我们提出了一个广泛的调查和祖先国家重建的鸟巢设计的雀形目，重点是早期的澳大利亚血统，包括几乎所有的雀形目家庭的成员在世界各地。大多数雀形目鸟建造开放的杯状巢，而少数鸟建造更精致的带屋顶的圆顶结构。我们提供了强有力的证据，尽管它们今天相对罕见，圆顶巢是由所有现代雀形目鸟类的共同祖先建造的。在雀形目鸟类早期的进化过程中，开放的杯巢至少独立地从封闭的圆顶进化了四次，其中至少有三次发生在澳大利亚大陆，产生了几个主要的杯巢分支，现在广泛分布，在雀形目鸟类中占主导地位。我们的研究结果表明，今天许多鸟类的普遍存在和相对简单的杯形巢进化了多次收敛，这表明适应性的好处比早期的屋顶设计。
The architectural diversity of nests in the passerine birds (order Passeriformes) is thought to have played an important role in the adaptive radiation of this group, which now comprises more than half of avian species and occupies nearly all terrestrial ecosystems. Here, we present an extensive survey and ancestral state reconstruction of nest design across the passerines, focusing on early Australian lineages and including members of nearly all passerine families worldwide. Most passerines build open cup-shaped nests, whereas a minority build more elaborate domed structures with roofs. We provide strong evidence that, despite their relative rarity today, domed nests were constructed by the common ancestor of all modern passerines. Open cup nests evolved from enclosed domes at least four times independently during early passerine evolution, at least three of which occurred on the Australian continent, yielding several primarily cup-nesting clades that are now widespread and numerically dominant among passerines. Our results show that the ubiquitous and relatively simple cup-shaped nests of many birds today evolved multiple times convergently, suggesting adaptive benefits over earlier roofed designs.
