Pelecaniformes

The Pelecaniformes are an order of medium-sized and large waterbirds found worldwide. As traditionally (but erroneously) defined, they encompass all birds that have feet with all four toes webbed. Hence, they were formerly also known by such names as totipalmates or steganopods. Under this obsolete definition, the Fregatidae (frigatebirds), Sulidae (gannets and boobies), Phalacrocoracidae (cormorants and shags), Anhingidae (darters), and Phaethontidae (tropicbirds) were included in the Pelecaniformes. Subsequent molecular and morphological studies indicate they are in fact not close relatives

AI overview

Pelecaniformes is an order of medium-sized to large waterbirds found around the world, traditionally defined by having all four toes webbed together. Modern genetic and physical studies have shown that this traditional grouping doesn't actually reflect how these birds are truly related to each other, making the traditional definition outdated.

Pelecaniformes as currently defined comprise the pelicans, shoebill and hamerkop, which form a clade within the order (suborder Pelecani), along with herons (Ardeidae) and ibises and spoonbills (Threskiornithidae); the relationships between Pelecani and the other two families are still being debated by taxonomists.
