List of Caprimulgiformes by population
From Wikipedia, the free encyclopedia
This is a list of Caprimulgiformes 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 Caprimulgiformes have had their numbers quantified.
The IOC World Bird List (version 15.1) recognizes 98 species of Caprimulgiformes.[1] This list follows IUCN classifications for species names. Where IUCN classifications differ from other ornithological authorities, alternative names are noted.

|---|---|---|---|---|---|---|
| New Caledonian nightjar | Eurostopodus exul | 0-49[2] | CR[2] | ?[2] | May be extinct. Species is known from a single individual, taken in 1939.[2] | |

| White-winged nightjar | Eleothreptus candicans | 600-1,700[4] | VU[4] |  [4] | Total population is estimated to be 1,000-2,499 individuals, but population may be larger, depending on species density in unsurveyed areas of Brazil.[4] |  |

Preliminary estimate.[6] | |
