Families

The order Anseriformes contains about 150 species of birds in three families: the Anhimidae (the screamers), Anseranatidae (the Magpie-goose), and the Anatidae, which includes over 140 species of waterfowl, among them the ducks, geese, and swans.

Evolution

Magpie Goose Anseranas semipalmata
Magpie Goose Anseranas semipalmata

The earliest known Anseriform is the recently discovered Vegavis, which lived during the Cretaceous period [1]. It is thought that the Anseriformes originated when the original Gallo-anserae (the group to which Anseriformes and Galliformes belong) split into the two main lineages. The extinct dromornithids represent early offshoots of the anseriform line, possibly derived from screamer-like ancestors. The ancestors of the Anseriformes developed the characteristic bill structure that they still share. The combination of the internal shape of the bill and a modified tongue acts as a suction pump to draw water in at the tip of the bill and expel it from the sides and rear; an array of fine filter plates called lamellae traps small particles, which are then licked off and swallowed.

All Anseriformes have this basic structure, but many have subsequently adopted alternative feeding strategies: geese graze on plants, the saw-billed ducks catch fish; even the screamers, which have bills that seem on first sight more like those of the game birds, still have vestigal lamellae. The prehistoric wading presbyornithids and the huge and possibly carnivorous dromornithids were even more bizarre.

Systematics

The Anseriformes and the Galliformes (pheasants etc) are the most primitive neognathous birds, and should follow ratites and tinamous in bird classification systems.

Families Struthionidae (ostriches) Rheidae (rheas) Casuariidae (emus etc. ... Genera Tinamus Nothocercus Crypturellus Rhynchotus Nothoprocta Nothura Taoniscus Eudromia Tinamotis The tinamous are one of the most ancient groups of bird, members of a South American bird family of about 47 species in 9 genera. ...


Anatidae systematics, especially regarding placement of some "odd" genera in the dabbling ducks or shelducks, is not fully resolved. See the Anatidae article for more information, and for alternate taxonomic approaches.

  • Anatalavis (Hornerstown Late Cretaceous/Early Paleocene of New Jersey, USA - London Clay Early Eocene of Walton-on-the-Naze, England) - Anseranatidae or basal
  • Proherodius (London Clay Early Eocene of London, England) - Presbyornithidae?
  • Paranyroca (Rosebud Early Miocene of Bennett County, USA) - Anatidae or own family?

In addition, a considerable number of Late Cretaceous and Paleogene fossils have been described where it is uncertain whether or not they are anseriforms. This is due to the fact that almost all families and orders of aquatic birds living today either originated or underwent a major radiation during that time, making it hard to decide whether some waterbird-like bone belongs into this family or is the product of parallel evolution in a different lineage due to adaptive pressures. In phylogenetics, basal members of a group are subgroups that diverged very early from the others. ... Paleogene (alternatively Palaeogene) period is a unit of geologic time that began 65 and ended 23 million years ago. ... Adaptive radiation describes the rapid speciation of a single or a few species to fill many ecological niches. ...

ADW: Anseriformes: Information (1074 words)
Anseriform birds are medium to large birds (30-180 cm; 230 g -22.5 kg).
Anseriform birds are herbivorous and feed primarily on leaves, stems, flowers, roots, seeds of aquatic vegetation.
There appears to be support for several different sister group hypotheses: anseriforms sister to galliforms (gamebirds); anseriforms sister to ciconiiforms (herons, ibises, storks); or anseriforms sister to phoenicopteriforms (flamingos).
Anseriformes - Wikipedia, the free encyclopedia (364 words)
It is thought that the Anseriformes originated when two groups of specialised filter feeders diverged from the Charadriiformes (plovers, gulls and allies) by evolving different mechanisims to filter small food particles from water.
All Anseriformes have this basic structure, but many have subsequently adopted alternative feeding strategies: geese graze on plants, the saw-billed ducks catch fish; even the screamers, which have bills that seem on first sight more like those of the game birds, still have vestigal lamellae.
The Anseriformes and the Galliformes (pheasants etc) are ancestral to neognathous birds, and should follow ratites and tinamous in bird classification systems.
