Otidae

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