Passerea

Passerea is a clade of birds that was created by Jarvis et al. (2014). Their study recovered two clades in Neoaves, Passerea and Columbae, both clades are unique in their ways, but are also similar. Which included the foot-diving of grebes, and both loons and cormorants. This data was not recovered in other studies.
