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.

New Caledonian nightjar Eurostopodus exul 1-49[2] CR[2] ?[2] There is only one specimen ever taken in 1939.[2]
Jamaican poorwill Siphonorhis americana 1-49[3] CR[3] ?[3] No records since 1860.[3] File:Extinct birds (Plate 5a) (6754846679).jpg
White-winged nightjar Eleothreptus candicans 600-1,700[4] VU[4] Decrease[4] Actual population may be larger.[4] File:Bacurau-do-rabo-branco.jpeg
Puerto Rican nightjar Caprimulgus noctitherus 930-1,300[5] EN[5] Decrease[5] This estimate is based on 712 males found within a portion of its range.[5] File:Puerto Rican nightjar sitting in leaves.jpg
Solomons nightjar Eurostopodus nigripennis 1,000-2,499[6] VU[6] Decrease[6] Estimate from lack of records and species small range.[6] File:Solomons nightjar Peter Rabenstein 2019.jpg
Palau nightjar Caprimulgus phalaena 1,000-2,499[7] NT[7] Steady[7] Preliminary estimate.[7]

Sickle-winged nightjar Eleothreptus anomalus 2,500-52,000[10] VU[10] Decrease[10] Large population variation is due to the common appearances, but apparent scarcity of the species (i.e. they are mostly nocturnal, which makes observing them harder, and they often only a lone individual is sighted).[10]
Least poorwill Siphonorhis brewsteri 4,140[11] NT[11] Decrease[11] Estimate is calculated from population density and available habitat.[11]
Salvadori's nightjar Caprimulgus pulchellus 6,000-15,000[12] NT[12] Decrease[12] Estimate comes from limited available habitat.[12]
