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.
| 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] |  |
