which has been adopted here. The placement of the New World vultures has been unclear since the early 1990s. The reason for this is the controversial systematic history of the New World vultures as they were assumed to be more related to (or a subfamily of) Ciconiidae (the storks) after Sibley and Ahlquist work on their DNA-DNA hybridization studies conducted in the late 1970s and throughout the 1980s.
