Editing Nightjar (section)

==Conservation and status==
Some species of nightjars are threatened with extinction. Road-kills of this species by cars are thought to be a major cause of mortality for many members of the family because of their habit of resting and roosting on roads.<ref>{{cite journal |last1=Jackson |first1=H.D. |last2=Slotow |first2=R.|title=A review of Afrotropical nightjar mortality, mainly road kills|journal=Ostrich|date=10 July 2015|volume=73|issue=3–4|pages=147–161|doi=10.1080/00306525.2002.11446745|s2cid=87154795}}</ref>

They also usually nest on the ground, laying one or two patterned eggs directly onto bare ground. Nightjars possibly move their eggs and chicks from the nesting site in the event of danger by carrying them in their mouths. This suggestion has been repeated many times in ornithology books, but surveys of nightjar research have found very little evidence to support this idea.<ref>{{cite journal|author=Jackson, H.D.|year=2007|title=A review of the evidence for the translocation of eggs and young by nightjars (Caprimulgidae)|journal=[[Ostrich: Journal of African Ornithology]] |volume=78|issue=3|pages=561–572|doi=10.2989/OSTRICH.2007.78.3.2.313|s2cid=84823011}}</ref><ref>{{cite journal|author=Jackson, H.D.|year=1985|title=Commentary and Observations on the Alleged Transportation of Eggs and Young by Caprimulgids|url=http://sora.unm.edu/sites/default/files/journals/wilson/v097n03/p0381-p0385.pdf |journal=[[Wilson Bulletin]]|volume=97|issue=3|pages=381–385}}</ref>

Developing conservation strategies for some species presents a particular challenge in that scientists do not have enough data to determine whether or not a species is endangered due to the difficulty in locating, identifying, and/or categorizing their limited number (e.g. 10,000) known to exist, a good example being the [[Vaurie's nightjar]] in [[China]]'s south-western [[Xinjiang]] Province (as seen only once in-hand). Surveys in the 1970s and 1990s failed to find the species.,<ref>''[[Handbook of the Birds of the World]]'', Volume 5, [[Birdlife International]]/[[Lynx Edicions]], 1999</ref> implying that the species has become extinct, endangered, or found only in a few small areas.
