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

The shoebill (Balaeniceps rex), also known as the whale-headed stork, whalebill, and shoe-billed stork, is a large long-legged wading bird. It is named for its enormous, shoe-shaped bill. It has a somewhat stork-like overall form and was previously classified as a stork in the order Ciconiiformes, but genetic evidence places it with pelicans and herons in the Pelecaniformes. Adults are mainly grey, while juveniles are browner. It lives in tropical East Africa in large swamps from South Sudan to Zambia.

It is the only living species in the genus Scopus and the family Scopidae. The species and family was long thought to sit with the Ciconiiformes but is now placed with the Pelecaniformes, and its closest relatives are thought to be the pelicans and the shoebill. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name after the Afrikaans word for hammerhead. It is a medium-sized waterbird with brown p

The Pelecanidae is a family of pelecaniform birds within the Pelecani that contains three genera: the extinct Eopelecanus and Miopelecanus and the extant Pelecanus.

genus of birds

Torotix is a Late Cretaceous genus of aquatic birds. They lived along the shores of the Western Interior Seaway, but it is not clear whether they were seabirds or freshwater birds, as the genus is only known from a humerus. Consequently, the genus contains only one known species, Torotix clemensi. T. clemensi is represented by a single fossil specimen, a partial humerus (upper arm bone) recovered from the Lance formation of Wyoming. Its deposits are dated to the very end of the Cretaceous period, 66 million years ago.

Hokkaidornis is an extinct genus of penguin-like plotopterid from the Late Oligocene of Hokkaido, Japan.
