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] |  |

Wobbegong is the common name given to the 12 species of carpet sharks in the family Orectolobidae. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan. The word wobbegong is believed to come from an Australian Aboriginal language, meaning "shaggy beard", referring to the growths around the mouth of the shark of the western Pacific.
This article is a list of biological species, subspecies, and evolutionary significant units that are known to have become extinct during the Holocene, the current geologic epoch, ordered by their known or approximate date of disappearance from oldest to most recent.
Nisaetus is a genus of subfamily Aquilinae found mainly in tropical Asia. They were earlier placed within the genus Spizaetus but molecular studies show that the Old World representatives were closer to the genus Ictinaetus than to the New World Spizaetus. They are slender-bodied, medium-sized hawk-eagles with rounded wings, long feathered legs, barred wings, crests and usually adapted to forest habitats.
