Editing Anseriformes (section)

==Taxonomy==
The Anseriformes and the [[Galliformes]] ([[pheasants]], etc.) belong to a common group, the [[Fowl|Galloanserae]]. They are the most primitive [[neognathous]] birds, and as such they should follow the [[Palaeognathae]] ([[ratite]]s and [[tinamou]]s) in bird classification systems. Several unusual extinct families of birds like the albatross-like [[Pelagornithidae|pseudotooth birds]] and the giant flightless [[Gastornithidae|gastornithids]] and [[Dromornithidae|mihirung]]s have been found to be stem-anseriforms based on common features found in the skull region, beak physiology and pelvic region.<ref name="andors1992">{{cite journal | last1 = Andors | first1 = A. | year = 1992 | title = Reappraisal of the Eocene groundbird ''Diatryma'' (Aves: Anserimorphae) | journal = Science Series Natural History Museum of Los Angeles County | volume = 36 | pages = 109–125}}</ref><ref name="murrayvickers2004">{{cite book | last1 = Murrary | first1 = P.F | last2 = Vickers-Rich | first2 = P. | year = 2004 | title = Magnificent Mihirungs: The Colossal Flightless Birds of the Australian Dreamtime | publisher = Indiana University Press}}</ref><ref name="bourdon2005">{{cite journal | last1 = Bourdon | first1 = E. | year = 2005 | title = Osteological evidence for sister group relationship between pseudo-toothed birds (Aves: Odontopterygiformes) and waterfowls (Anseriformes) | pmid = 16240103 | journal = Naturwissenschaften | volume = 92 | issue = 12 | pages = 586–91 | doi=10.1007/s00114-005-0047-0| bibcode = 2005NW.....92..586B | s2cid = 9453177 }}</ref><ref name="agnolín2007">{{cite journal | last1 = Agnolín | first1 = F. | year = 2007 | title = ''Brontornis burmeisteri'' Moreno & Mercerat, un Anseriformes (Aves) gigante del Mioceno Medio de Patagonia, Argentina. | journal = Revista del Museo Argentino de Ciencias Naturales | volume = 9 | pages = 15–25 | doi=10.22179/revmacn.9.361| doi-access = free }}</ref><ref name="livezeyzusi2007">{{cite journal | last1 = Livezey | first1 = B.C. | last2 = Zusi | first2 = R.L. | year = 2007 | title = Higher-order phylogeny of modern birds (Theropoda, Aves: Neornithes) based on comparative anatomy.

===Systematics===
[[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. Anatidae is traditionally divided into subfamilies Anatinae and Anserinae.<ref name=Gonzalez2009>{{ cite journal | last1=Gonzalez | first1=J. | last2=Düttmann | first2=H. | last3=Wink | first3=M. | year=2009 | title=Phylogenetic relationships based on two mitochondrial genes and hybridization patterns in Anatidae | journal=Journal of Zoology | volume=279 | issue= 3| pages=310–318 | doi=10.1111/j.1469-7998.2009.00622.x }}</ref> The Anatinae consists of tribes [[Anatini]], [[Aythyini]], [[Mergini]] and [[Tadornini]].

In addition, a considerable number of mainly Late Cretaceous and [[Paleogene]] fossils have been described where it is uncertain whether or not they are anseriforms. This is because almost all orders of aquatic birds living today either originated or underwent a major [[Adaptive radiation|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.
