ORDER FAMILY FAMILY NOTES ON CLASSIFICATION
Tinamiformes Tinamous Tinamidae “Early Bird” DNA study suggested that flighted tinamous may have evolved from flightless ratites (Hackett et al. 2008); but recent analyses reposition tinamous (with moas) as the outgroup to the traditional ratites (Hadrath & Baker 2012)
Struthioniformes Ostriches Struthionidae
Rheiformes Rheas Rheidae
Casuariiformes Cassowaries Casuariidae
Emu Dromaiidae
Apterygiformes Kiwis Apterygidae
Anseriformes Screamers Anhimidae
Magpie Goose Anseranatidae
Ducks, Geese and Swans Anatidae
Galliformes Megapodes Megapodiidae
Chachalacas, Curassows and Guans Cracidae
Guineafowl Numididae
New World Quail Odontophoridae Ptilopachus partridges of Africa are related to New World quails (Odontophoridae) and in turn to the guineafowl (Numididae), not to members of Phasianidae (Crowe et al. 2006, Crowe 2010, Cohen et al 2012)
Pheasants and Allies Phasianidae
Gaviiformes Loons Gaviidae
Sphenisciformes Penguins Spheniscidae
Procellariiformes Albatrosses Diomedeidae
Petrels, Shearwaters Procellariidae
Storm Petrels Hydrobatidae The subfamilies Hydrobatinae and Oceanitinae may not be sister taxa and therefore would be separate families (Nunn and Stanley 1998; Hackett et al. 2008; Christidis and Boles 2008)
Diving Petrels Pelecanoididae
Podicipediformes Grebes Podicipedidae Grebes and flamingos are sister lineages (Mayr 2008, Hackett et al 2008)
Phoenicopteriformes Flamingos Phoenicopteridae
Phaethontiformes Tropicbirds Phaethontidae The tropicbirds (Phaethontidae) do not belong in the Pelecaniformes and merit treatment as the Order Phaethontiformes (Hackett et al. 2008, Christidis and Boles 2008)
Ciconiiformes Storks Ciconiidae The Ciconiiformes now includes only one family; the storks (Ciconiidae). Ibises and spoonbills (Threskiornithidae)and herons (Ardeidae) are moved the Pelecaniformes (Hackett et al 2008).
Pelecaniformes Ibises, Spoonbills Threskiornithidae Ibises and spoonbills (Threskiornithidae) and herons (Ardeidae) are sister taxa (Hackett et al. 2008); Some classifications separate as Ardeiformes. Ibises are polyphyletic with Old World species (plus spoonbills) and New World species on separate lineages (Chesser et al 2010, Ramirez et al 2010 Brasil IOC poster);
Herons, Bitterns Ardeidae
Hamerkop Scopidae
Shoebill Balaenicipitidae

Anhingas, Darters Anhingidae
Accipitriformes New World Vultures Cathartidae SACC elevates the New    World Vultures (Cathartidae) to a separate order, the Cathartiformes
Secretarybird Sagittariidae Secretarybird is best treated as a monotypic family Sagittariidae in accord with the Tree of Life phylogeny (Hackett et al. 2008)
Ospreys Pandionidae Ospreys are returned to the family Pandionidae in accord with the Tree of Life phylogeny (Hackett et al. 2008)
Kites, Hawks and Eagles Accipitridae Many changes based on the molecular phylogenies  are underway such as subdivision of hawk-eagles and true eagles, breakup of Aquila eagles etc. Will revise when results stabilize.
Otidiformes Bustards Otididae Move bustards (Otididae) from the Gruiformes to their own Order, the Otidiformes (Hackett et al. 2008); rearrange taxa split from classical Gruiformes because they are not close relatives.
Mesitornithiformes Mesites Mesitornithidae Move mesites (Mesitornithidae) from the Gruiformes to their own Order, the Mesitornithiformes (Hackett et al. 2008). Uncertain relationships to grebes/flamingos (Ericson et. al., 2006), or pigeons (Hackett et al 2008)
Cariamiformes Seriemas Cariamidae Move seriemas (Cariamidae)  from the Gruiformes to their own Order, the Cariamiformes (Hackett et al. 2008)
Eurypygiformes Kagu Rhynochetidae The Kagu (Rhynochetidae) and Sunbittern (Eurypygidae) are sister families removed from the Gruiformes to a new Order, tentatively named the “Eurypygiformes” (Hackett et al. 2008).
Sunbittern Eurypygidae
Gruiformes Flufftails Sarothruridae Long recognized to be an    artificial assemblage of taxa, the Gruiformes now is restricted to flufftails, finfoots, rails, trumpeters, cranes, and Limpkin (Hackett et al. 2008).
Finfoots Heliornithidae The finfoots (Heliornithidae) and flufftails (Sarothruridae) may be sister taxa (Hackett et al. 2008)
Rails, Crakes and Coots Rallidae
Trumpeters Psophiidae
Cranes Gruidae
Limpkin Aramidae
Charadriiformes Buttonquails Turnicidae The buttonquails (Turnicidae) belong in the Charadriiformes, not the Gruiformes (Hackett et al. 2008); Inclusion of Quail-plover (Ortyxelos) in this family is tentative (REFS)
Stone-curlews, Thick-knees Burhinidae
Sheathbills Chionidae
Magellanic Plover Pluvianellidae The Magellanic Plover (Pluvianellus) is most closely related to the sheathbills (Chionidae) but treated as a monotypic family by the SACC.
Oystercatchers Haematopodidae
Crab-plover Dromadidae Latest molecular data place Crab-plover as the outgroup relative of coursers and pratincoles (Glareolidae)(Pereira and Baker 2010); Change position in sequence
Ibisbill Ibidorhynchidae
Stilts, Avocets Recurvirostridae
Plovers Charadriidae Latest studies (Baker et al MS) support inclusion of Pluvialis plovers in the Charadriidae (Baker et al 2007, TOL)
Egyptian Plover Pluvianidae The Egyptian Plover (Pluvianus) does not belong to the Glareolidae. It is a separate lineage that is the outgroup to plovers, ibisbill, stilts and their allies (Hackett et al. 2008).    Therefore separated here to its own family tentatively named “Pluvianidae”
Painted Snipes Rostratulidae Painted Snipes and Jacanas are sister families
Jacanas Jacanidae
Plains-wanderer Pedionomidae
Seedsnipes Thinocoridae
Sandpipers, Snipes Scolopacidae
Coursers, Pratincoles Glareolidae
Gulls, Terns and Skimmers Laridae The skimmers and (noddy) terns are embedded among the gulls in a monophyletic clade; separation of the families Rynchopidae and Sternidae would render the gull family Laridae paraphyletic    relative to these other two groups (Baker et al. 2008).DNA analysis confirm that Gygis is a noddy (Baker et al 2007, Odeen et al 2010) and support the English name “White Noddy”.
Skuas Stercorariidae
Auks Alcidae
Pterocliformes Sandgrouse Pteroclidae The sandgrouse  are treated as a separate Order Pteroclidiformes; they are not shorebirds (Charadriiformes), but relationships to pigeons (Columbidae) need confirmation

Potoos Nyctibiidae
Nightjars Caprimulgidae The eared nightjars (Eurostopodus) are the sister taxon to rest of the Caprimulgidae (Barrowclough et al 2006, Larsen et al. 2007), but they are not equivalent in rank to other families in the Caprimulgiformes.
Apodiformes Owlet-nightjars Aegothelidae The owlet-nightjars (Aegothelidae) are the sister taxon to treeswifts and in turn to the swifts and hummingbirds; hence are included in the Apodiformes (Hackett et al. 2008,    Christidis and Boles 2008)
Treeswifts Hemiprocnidae
Swifts Apodidae
Hummingbirds Trochilidae Revise the hummingbird classification to  follow the molecular phylogeny (McGuire et al. 2007, 2009) with Topaza and Florisuga basal.
Coliiformes Mousebirds Coliidae
Trogoniformes Trogons Trogonidae
Leptosomiformes Cuckoo Roller Leptosomidae The Cuckoo Roller is the only member of an ancient lineage (not Coraciiformes) with no known relatives among modern birds and thus put into a separate Order, Leptosomiformes (Hackett et al. 2008)

Ground Rollers Brachypteraciidae
Kingfishers Alcedinidae The kingfishers (Alcedinidae) comprise three monophyletic clades (Alcedininae, Cerylinae, and Daceloninae) (Moyle 2007); some taxonomists elevate them to family status (Sibley and  Monroe 1990, Christidis and Boles 2008)
Todies Todidae
Motmots Momotidae
Bee-eaters Meropidae
Bucerotiformes Hoopoes Upupidae Separation of the hoopoes and hornbills as the Order Bucerotiformes maintains monophyly of the Coraciiformes without submerging the Piciformes and Trogoniformes into the Coraciiformes (Hackett et al. 2008).

Ground Hornbills Bucorvidae
Piciformes Jacamars Galbulidae The jacamars (Galbulidae) and  puffbirds (Bucconidae) are well-established sister taxa (SACC, Hackett et al. 2008), with evidence favoring inclusion in the Piciformes, rather than a    separate Order Galbuliformes (TOL, Ericson et al. 2006; cf SACC, Fain & Houde 2004)

Further restructuring and revisions of genera in this family will be required.
Dapple-throat and allies Arcanatoridae It is unclear whether Promeropidae and Arcanatoridae are together or represent two independent basal branches. Each of them go further back in time than almost any other extant lineage in the Passerida … which would argue for accepting them as two families (Johansson et al 2008a Fjeldså, July 2012)
Sugarbirds and allies Promeropidae Expand to include Kakamega (not a babbler), Modulatrix, Arcanator, as well as Promerops (Barker et al 2004, Johanssen et al 2008)
