This is a list of Psittaciformes 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.
This list is not comprehensive, as not all Psittaciformes have had their numbers quantified. All numbers, unless explicitly stated in the notes, only count individuals in the wild; IUCN does not consider species held in captivity in its population estimates.
The IOC World Bird List (version 15.1) recognizes 406 species of Psittaciformes, 14 of which are extinct.
This list follows IUCN classifications for species names and taxonomy. Where IUCN classifications differ from other ornithological authorities, alternative names and taxonomies are noted.
