	Kites, Hawks & Eagles	Accipitridae

	Sunbittern	Eurypygidae

	Crab-plover	Dromadidae
	Ibisbill	Ibidorhynchidae
	Stilts, Avocets	Recurvirostridae
	Plovers	Charadriidae	The golden plovers (Pluvialis) are a separate lineage that may merit family status (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"

	Jacanas	Jacanidae
	Plains-wanderer	Pedionomidae
	Seedsnipes	Thinocoridae
	Sandpipers, Snipes	Scolopacidae
	Coursers, Pratincoles	Glareolidae
	Gulls, Terns & Skimmers	Laridae	The skimmers and 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).
	Skuas	Stercorariidae
	Auks	Alcidae
Pteroclidiformes	Sandgrouse	Pteroclididae	The sandgrouse (Pteroclididae) are treated as a separate Order Pteroclidiformes because their relationships to other modern birds remain uncertain.
Columbiformes	Pigeons, Doves	Columbidae
Psittaciformes	New Zealand Parrots	Strigopidae	Parrots (Psittaciformes) are the sister group to the Passeriformes (Hackett et al. 2008); resequence in future. The New Zealand parrots are a basal lineage that is sister to all other parrots; elevate to family status (Christidis & Boles (2008)

	Oilbird	Steatornithidae
	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

Coraciiformes	Rollers	Coraciidae
	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).
	Wood Hoopoes	Phoeniculidae	The hoopoes (Upupidae) and wood hoopoes (Phoeniculidae) are sister taxa, related in turn to the hornbills (Hackett et al. 2008)
