This is a list of Cuculiformes 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 incomprehensive, as not all Cuculiformes have had their numbers quantified.
The IOC World Bird List (version 15.1) recognizes 156 species of Cuculiformes, two 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.
Some species included as members of Cuculiformes are extinct:
Snail-eating coua, or Delalande's coua (Coua delalandei) - last seen in 1834.
St. Helena cuckoo (Nannococcyx psix) - last seen in 1550.

Violaceous coucal Centropus violaceus 6,700-61,000 Biak coucal Centropus chalybeus >10,000 No population estimates are available. Population "is not thought to be below 10,000 mature individuals." Short-toed coucal Centropus rectunguis >10,000 The global population size has not been quantified. Population is "considered highly unlikely to meet or approach the population size threshold for listing as threatened (<10,000 mature individuals)."

Note that IOC taxonomy splits an additional species, the scaled ground-cuckoo, from this species.
