List of Columbiformes by population
This is a list of Columbiformes 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 Columbiformes have had their populations quantified.
The IOC World Bird List recognizes 352 species of Columbiformes, 13 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.
