Otidae is a clade that includes the superorders

Otidimorphae The Otidimorphae is a clade of birds that contains the orders Cuculiformes (cuckoos), Musophagiformes (turacos), and Otidiformes (bustards) identified in 2014 by genome analysis. While the bustards seem to be related to the turaco The tura ...

Passerea Passerea is a clade of neoavian birds that was proposed by Jarvis ''et al''. (2014). Their genomic analysis recovered two major clades within Neoaves, Passerea and Columbea, and concluded that both clades appear to have many ecologically driven ...

, other analyses of large data matrices have not recovered a clade comprising Otidimorphae and Strisores, raising questions about the monophyly of Otidae.
