List of Psittaciformes by population

From Wikipedia, the free encyclopedia

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 otherwise in the notes, regard individuals in the wild only.
