This included a strongly supported
clade (100 % BS on most branches) that comprised the three groups
of vocal learners (parrots, songbirds, and hummingbirds) and most
of the nonpredatory core landbirds, a monophyletic
clade of diurnal birds
of prey and seriemas (albeit with low 40 % BS), and a monophyletic
clade of all aquatic and semiaquatic species
of Passerea and Columbea (also with low 20 % BS)(Fig. 4D).
Results for different genomic partitions, methods, and data types are consistent with or contradict
clades in our TENT ExaML, TENT MP - EST *, and exon - only trees and previous studies

The tree revealed the first divergence within extant Neoaves, resulting in two fully supported, reciprocally monophyletic sister
clades that we named Passerea (after its most speciose group Passeriformes) and Columbea (after its most speciose group Columbiformes)(Fig. 1; see SM6 for rationale
of clade names).
Within Neoaves, they proposed several large new
clades, including a waterbird
clade containing taxa such as penguins, pelicans, and loons, as well as a landbird
clade containing woodpeckers, birds
of prey, parrots, and songbirds.
Within Passerea, the TENT strongly confirmed the monophyly
of two large closely related
clades that we refer to as core landbirds (Telluraves) and core waterbirds (Aequornithia)(8, 16, 17, 27, 36, 59); we use the term «core» instead
of «higher» to prevent interpretation that these groups are more advanced or more recently evolved than other birds.
Within core landbirds, we found 100 % BS for a previously more weakly supported
clade (Australaves) containing seriemas (historically placed in Gruiformes), falcons (historically grouped with other diurnal birds
of prey), parrots (historically difficult to place), and Passeriformes and a sister
clade (Afroaves) containing Accipitrimorphae birds
of prey, owls, mousebirds, woodpeckers, and bee eaters, among others (Fig. 1)(8, 17, 26, 29, 60).
