Passerea is aclade ofneoavian birds that was proposed by Jarviset al. (2014).^[3] Their genomic analysis recovered two major clades withinNeoaves, Passerea andColumbea, and concluded that both clades appear to have many ecologically driven convergent traits.

According to Jarvis (2014), these convergences include the foot-propelled diving trait ofgrebes in Columbea withloons andcormorants in Passerea; the wading-feeding trait offlamingos in Columbea withibises andegrets in Passerea; andpigeons andsandgrouse in Columbea withshorebirds (killdeer) in Passerea. For Jarvis (2014), these long-known trait and morphological alliances suggest that some of the traditional nongenomic trait classifications are based onpolyphyletic assemblages.

Passerea was not recovered in other studies.^[4][1]

Cladogram of Passerea relationships based on Jarviset al. (2014)^[3] with some clade names after Yuriet al. (2013)^[5] and Kimballet al. 2013.^[6]

The followingcladogram illustrates the proposed relationships between bird clades of Passerea. This consensus phylogeny of birds is based on phylogenomic data, reflecting a recent phylogenomic supertree analysis per Stiller et al. (2024).^[2]
