Passerea

Passerea  is a clade that was proposed by Jarvis et al. (2014). Jarvis et al. rescued two major clades within Neoaves, Passerea and Columbea, and concluded that both clades appear to have many ecologically driven convergent traits.

According to Jarvis (2014), these convergences include the footpropelled diving trait of grebes in Columbea with loons and cormorants in Passerea; the wading-feeding trait of flamingos in Columbea with ibises and egrets in Passerea; and pigeons and sandgrouse in Columbea with shorebirds (killdeer) in Passerea. For Jarvis (2014), these long-known trait and morphological alliances suggest that some of the traditional nongenomic trait classifications are based on polyphyletic assemblages.

Nevertheless, Passerea was not rescued in further studies.
