Mary's College of Maryland, St. Nest data for Australian passerine species electronic supplementary material, table S1 and world passerine families electronic supplementary material, table S2 , results of BiSSE analyses electronic supplementary material, table S3 , and ancestral state reconstructions of nest characteristics electronic supplementary material, figure S1 and electronic supplementary material, figure S2 have been uploaded as part of the electronic supplementary material. 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.
