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.

Species by global population

Common name	Binomial name	Population	Status	Trend	Notes	Image
New Caledonian owlet-nightjar	Aegotheles savesi	1-49[1]	CR[1]	[1]	The most recent sighting is in 1998.[1]
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]
White-winged nightjar	Eleothreptus candicans	600-1,700[4]	VU[4]	[4]	Actual population may be larger.[4]
Puerto Rican nightjar	Caprimulgus noctitherus	930-1,300[5]	EN[5]	[5]	This estimate is based on 712 males found within a portion of its range.[5]
Solomons nightjar	Eurostopodus nigripennis	1,000-2,499[6]	VU[6]	[6]	Estimate from lack of records and species small range.[6]
Palau nightjar	Caprimulgus phalaena	1,000-2,499[7]	NT[7]	[7]	Preliminary estimate.[7]
Prigogine's nightjar	Caprimulgus prigoginei	2,500-9,999[8]	EN[8]	[8]	Estimate comes from consideration of habitat and last recorded specimen was in 1955.[8]
Satanic nightjar	Eurostopodus diabolicus	2,500-9,999[9]	VU[9]	[9]
Sickle-winged nightjar	Eleothreptus anomalus	2,500-52,000[10]	VU[10]	[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]	[11]	Estimate is calculated from population density and available habitat.[11]
Salvadori's nightjar	Caprimulgus pulchellus	6,000-15,000[12]	NT[12]	[12]	Estimate comes from limited available habitat.[12]
Bonaparte's nightjar	Caprimulgus concretus	10,000-19,999[13]	VU[13]	[13]	Preliminary estimate.[13]
Choco poorwill	Nyctiphrynus rosenbergi	10,000-19,999[14]	LC[14]	[14]	Preliminary estimate.[14]

Red-necked nightjar	Caprimulgus ruficollis	575,000-770,000[26]	NT[26]	[26]	Consists of two subspecies, so these estimates are very preliminary.[26]
