List of Apodiformes by population

This is a list of Apodiformes 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.

Members of Apodiformes include the swifts, treeswifts, and hummingbirds. Note that some ornithological authorities (e.g., IUCN/BirdLife International) ^[1] no longer recognize Apodiformes, and place all members within Caprimulgiformes. However, Apodiformes is maintained as a separate order here to match IOC taxonomy (IOC World Bird List version 15.1). ^[2] For more discussion of this taxonomic complex, see Strisores.

This list is not comprehensive, as not all Apodiformes have had their numbers quantified.

The IOC World Bird List (version 15.1) recognizes 480 species of Apodiformes, one of which is extinct. ^{[3] [4]}

One member of Apodiformes is extinct:

• Brace's emerald (Riccordia bracei) - went extinct circa 1877. ^[5]
