Anatidae

The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and, in some cases, diving in at least shallow water. The family contains around 174 species in 43 genera (the magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae).

species of swan

The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, migrating to more southerly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining feral population derived from introduced Canada geese is also found in New Zealand.

Garganornis (meaning "Gargano bird") is an extinct genus of enormous flightless anatid waterfowl from the Late Miocene of Gargano, Italy. The genus contains one species, G. ballmanni, named by Meijer in 2014. Its enormous size is thought to have been an adaptation to living in exposed, open areas with no terrestrial predators, and as a deterrent to the indigenous aerial predators like the eagle Garganoaetus and the giant barn owl Tyto gigantea.

Thambetochen is an extinct genus of moa-nalo duck. It contains two species, the Maui Nui moa-nalo (T. chauliodous) and the smaller O'ahu moa-nalo (T. xanion). thumb|upright|left|Restoration of T. xanion thumb|upright|left|Restoration of T. chauliodous and Ptaiochen pau The former was found on Maui and Molokai on Hawaii, the latter was found on Oahu. These birds were large, flightless ducks, with robust legs but small wings, which had evolved in isolation, on islands without terrestrial mammals. Their beaks had tooth-like lamellae and their diet was plants which they digested throug

Talpanas lippa, the Kauaʻi mole duck, is an extinct species of duck. It was first described by Andrew N. Iwaniuk, Storrs L. Olson, and Helen F. James in the journal Zootaxa in November 2009. It is the only known member of the genus Talpanas. It was endemic to the Hawaiian island of Kauaʻi where the fossil remains were unearthed in the Makauwahi Cave, Maha‘ulepu. The archaeological association of the bones is about 6000 years BP (around 4050 BCE).
