Deep avian evolutionary relationships have been difficult to resolve as a result of a putative explosive radiation. Our studyexamined ∼32 kilobases of aligned nuclear DNA sequences from 19 independent loci for 169 species, representing all major extant
groups, and recovered a robust phylogeny from a genome-wide signal supported by multiple analytical methods. We documented
well-supported, previously unrecognized interordinal relationships (such as a sister relationship between passerines and parrots)
and corroborated previously contentious groupings (such as flamingos and grebes). Our conclusions challenge current classifications
and alter our understanding of trait evolution; for example, some diurnal birds evolved from nocturnal ancestors. Our results
provide a valuable resource for phylogenetic and comparative studies in birds.
