Systematics and evolution

Of the families in Pelecaniformes, only
Pelecanidae The Pelecanidae is a family of pelecaniformes, pelecaniform birds within the Pelecani that contains two genera: the extinct ''Eopelecanus'' and the extant ''Pelecanus''. The family was monotypy, monotypic until the description of ''Eopelecanus'' ...

has since been moved to their own order Phaethontiformes. Genetic analysis seems to show that the Pelecaniformes is actually closely related to the
Ardeidae The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus ...
and
Threskiornithidae The family Threskiornithidae includes 36 species of large wading birds. The family has been traditionally classified into two subfamilies, the ibises and the spoonbills; however recent genetic studies have cast doubt on this arrangement, and hav ...

, and as well as Suliformes and Pelecaniformes, all seem to have evolved from a common ancestor. The proposed

superorder has been suggested. In their landmark 2008 work ''Systematics and Taxonomy of Australian Birds'', Australian ornithologists Les Christidis and Walter E. Boles coined the name Phalacrocoraciformes for the group due to the much greater number of species of cormorants (

). However, this has not been taken up elsewhere. In 1994, American ornithologist Walter J. Bock wrote that the name Suloidea had been used consistently as a term for a superfamily containing the two families, so therefore "Sulidae" and not "Phalacrocoracidae" should take priority in any arrangement containing the two genera. In 2010, the AOU adopted the term Suliformes for the taxon. The IOC followed in 2011. In 1994, Martyn Kennedy and colleagues constructed a behavioural data set, with the resulting tree showing a high level of congruence with existing phylogenies based on genetics or morphology. It showed the darters as sister group to the cormorants and shags, with the gannets and boobies, then pelicans, then frigatebirds and lastly tropicbirds as progressively earlier offshoots.
