This is a list of Accipitriformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology. For the sake of the argument and their small species diversity, the family Cathartidae will be included in this list

This list is incomprehensive, as not all Accipitriformes have had their numbers quantified.
