List of Falconiformes by population

Last updated

This is a list of Falconiformes species by global population. While members of Falconiformes were once classified with the hawks, eagles, vultures, and kites of order Accipitriformes, recent genetic analysis indicates they are not close relatives of these birds. [1] [2] Version 15.1 of the IOC World Bird List describes 65 species within Falconiformes, two of which are extinct. [3] As of December 2025, BirdLife International has assessed 64 of these species (excepting rock kestrel). While not all of these species have had their populations quantified, species without estimates are also listed below in a separate table.

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.

There are two species listed as members of Falconiformes which are extinct. They are as follows:
