List of Ciconiiformes by population

This is a list of Ciconiiformes 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.
The IOC World Bird List recognizes 20 species of Ciconiiformes. As of December 2025, IUCN/BirdLife International have assessed the populations of all members of this order. This list follows IUCN classifications for species names. Where IUCN classifications differ from other ornithological authorities, alternative names are noted.
