This is a list of Piciformes 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 Piciformes have had their numbers quantified.
The IOC World Bird List (version 15.1) recognizes 448 species of Piciformes, one of which is 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.
One member of Piciformes is extinct:
Bermuda flicker (Colaptes oceanicus) - likely went extinct by mid-17th century.
