List of Gruiformes by population

This is a list of Gruiformes 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.

Not all Gruiformes have had their numbers quantified, but species without population estimates are included in a secondary table below.

The IOC World Bird List (version 15.1) recognizes 190 species of Gruiformes, 21 of which are extinct. Species status within Gruiformes is particularly unresolved compared to other orders. As of December 2025, IOC lists six species which are considered subspecies by IUCN/BirdLife International. Similarly, IUCN/BirdLife International list four species which still have subspecies status in IOC taxonomies. See 'Notes' column of included tables for more information on these taxonomic disputes.

This list follows IUCN classifications for species names and taxonomy. Where IUCN classifications differ from other ornithological authorities, alternative names and taxonomies are noted.

Several species included as members of Gruiformes are extinct:
