Phaethoquornithes is a clade of birds that contains Eurypygimorphae and Aequornithes, [3] which was first recovered by genome analysis in 2014. [4] Members of Eurypygimorphae were originally classified in the obsolete group Metaves,[ clarification needed ] and Aequornithes were classified as the sister taxon to Musophagiformes or Gruiformes. [5] [6]
This group has also been informally called Ardeae. [7] Older classifications have used Ardeae in a different sense, as a suborder of Ciconiiformes containing herons and related species. [8] George Sangster and colleagues in 2022 named and defined this clade in the PhyloCode as the least inclusive crown clade containing Phaethon aethereus and Pelecanus onocrotalus , but not Apus apus , Charadrius hiaticula , Musophaga violacea , or Passer domesticus .
