List of Caprimulgiformes by population

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] Decrease[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] Decrease[4] Actual population may be larger.[4]
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]
Solomons nightjar Eurostopodus nigripennis 1,000-2,499[6] VU[6] Decrease[6] Estimate from lack of records and species small range.[6]
Palau nightjar Caprimulgus phalaena 1,000-2,499[7] NT[7] Steady[7] Preliminary estimate.[7]
Prigogine's nightjar Caprimulgus prigoginei 2,500-9,999[8] EN[8] Decrease[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] Decrease[9]
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]
Bonaparte's nightjar Caprimulgus concretus 10,000-19,999[13] VU[13] Decrease[13] Preliminary estimate.[13]
Choco poorwill Nyctiphrynus rosenbergi 10,000-19,999[14] LC[14] Decrease[14] Preliminary estimate.[14]
Eared poorwill Nyctiphrynus mcleodii 20,000-49,999[15] LC[15] Decrease[15]
Yucatan poorwill Nyctiphrynus yucatanicus 20,000-49,999[16] LC[16] Decrease[16]

Tawny-collared nightjar Antrostomus salvini 50,000-499,999[21] LC[21] Decrease[21]
Antillean nighthawk Chordeiles gundlachii 200,000[22] LC[22] Steady[22]
Mexican whip-poor-will Antrostomus arizonae 320,000[23] LC[23] Decrease[23]
White-tailed nightjar Hydropsalis cayennensis 500,000-4,999,999[24] LC[24] Decrease[24]
Ocellated poorwill Nyctiphrynus ocellatus 500,000-4,999,999[25] LC[25] Decrease[25]
Red-necked nightjar Caprimulgus ruficollis 575,000-770,000[26] NT[26] Decrease[26] Consists of two subspecies, so these estimates are very preliminary.[26]
Common poorwill Phalaenoptilus nuttallii 1,700,000[27] LC[27] Steady[27]
Eastern whip-poor-will Antrostomus vociferus 1,800,000[28] NT[28] Steady[28]
Buff-collared nightjar Antrostomus ridgwayi 2,000,000[29] LC[29] Decrease[29]
European nightjar Caprimulgus europaeus 3,000,000-5,999,999[30] LC[30] Decrease[30] European population estimated at 1,230,000-2,200,000, so very preliminary estimate of global population.[30]
Rufous nightjar Antrostomus rufus 5,000,000-49,999,999[31] LC[31] Decrease[31]
Chuck-will's-widow Antrostomus carolinensis 5,700,000[32] NT[32] Decrease[32]
Pauraque Nyctidromus albicollis 20,000,000[33] LC[33] Steady[33]
