Biology:List of Coraciiformes by population

From HandWiki
Short description: none

Template:Birds by population sidebar This is a list of Coraciiformes 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 Coraciiformes have had their numbers quantified.

The IOC World Bird List (version 15.1) recognizes 186 species of Coraciiformes.[1][2] This list follows IUCN classifications for species names. Where IUCN classifications differ from other ornithological authorities, alternative names are noted.
