Aequornithes ( /iːkwɔːrˈnɪθiːz/, from Latin aequor, expanse of water + Greek ornithes, birds), or core water birds, [6] are defined as "the least inclusive clade containing Gaviidae and Phalacrocoracidae". [3]
The monophyly of the group is currently supported by several molecular phylogenetic studies. [7] [8] [9] [10]
Aequornithes includes the clades Gaviiformes, Sphenisciformes, Procellariiformes, Ciconiiformes, Suliformes and Pelecaniformes. It does not include several unrelated groups of aquatic birds such as flamingos and grebes ( Mirandornithes), shorebirds, gulls, and auks ( Charadriiformes), or the Anseriformes(waterfowl).
Based on a whole-genome analysis of the bird orders, the kagu and sunbittern ( Eurypygiformes) and the three species of tropicbirds ( Phaethontiformes) together styled as the Eurypygimorphae are the closest sister group of the Aequornithes, [6] in a clade later named Phaethoquornithes. [11]
