Otidae

Otidae is a clade that includes the superorders Otidimorphae (bustards, turacos, and cuckoos) and Cypselomorphae (nightbirds, swifts, and hummingbirds). It was identified in 2014 by genome analysis. Before it was thought that Cypselomorphae was closely related to birds such as pigeons, flamingos, tropicbirds, and the kagu in the possibly polyphyletic taxon Metaves. They occupy a basal branch of the clade Passerea.
