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. This list follows IUCN classifications for species names. Where IUCN classifications differ from other ornithological authorities, alternative names are noted.

Species is known from a single individual, taken in 1939.Jamaican poorwillSiphonorhis americana1-49 ?May be extinct. No records since 1860. White-winged nightjarEleothreptus candicans 600-1,700 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. Solomons nightjarEurostopodus nigripennis800-2,499 Palau nightjarCaprimulgus phalaena1,000-2,499 Preliminary estimate. Sickle-winged nightjar Eleothreptus anomalus 2,500-52,000 Values are for total population. Large population variation is due to the common observation, but apparent scarcity of the species. Puerto Rican nightjar Caprimulgus noctitherus 2,700-9,900 Total population is estimated to be 4,100-14,900 individuals. Least poorwill Siphonorhis brewsteri 4,140 Total population is estimated to be 6,210 individuals. Bonaparte's nightjar Caprimulgus concretus 10,000-19,999 Preliminary estimate.

No confirmed records since last recorded specimen was in 1955. Salvadori's nightjar Caprimulgus pulchellus unknown Heinrich's nightjar (Satanic nightjar)Eurostopodus diabolicus unknown No empirical population data, but given large range, population is unlikely to be small.
