The idea that the Oilbird belongs somewhere within the Caprimulgiformes is nowadays generally recognized, and this has been supported by studies using egg-white protein.
Most systematists have tended to place it next to the owls, at the beginning of the Caprimulgiformes, and it is usually believed to be an early offshoot of the order.
