Comment:
The phylogeny of Strisores (a clade encompassing hummingbirds, swifts, owlet-nightjars, frogmouths, nightjars, potoos, and the oilbird) is contentious. IOC (v8.2, 2018) '[proposes] to merge Apodiformes, including owlet-nightjars as well as swifts and hummingbirds, with the Caprimulgiform nightbirds to define a spectacular basal adaptive radiation of Neoaves.' ITIS here follows Zoonomen (2018) in recognizing potoos and the oilbird at order rank, Nyctibiiformes and Steatornithiformes respectively. This approach was argued and adopted by the South American Classification Committee by Van Remsen (February, 2016) in Proposal 703 (http://www.museum.lsu.edu/~Remsen/SACCprop703.htm)
