Working out conservation strategies for some species of nightjar presents a particular challenge common to other hard-to-see families of birds; in a few cases, scientists do not have enough data on whether a bird is rare or not. This has nothing to do with any lack of effort. It reflects, rather, the difficulty in locating and identifying a small number of those species of birds among the 10,000 or so that exist in the world, given the limitations of human beings. A perfect example is the [[Vaurie's nightjar]] in [[China]]'s south-western [[Xinjiang]]. It has been seen for certain only once, in 1929, a specimen that was held in the hand. Surveys in the 1970s and 1990s failed to find it.<ref>''[[Handbook of the Birds of the World]]'', Volume 5, [[Birdlife International]]/[[Lynx Edicions]], 1999</ref> It is perfectly possible that it has evolved as a species that can really be identified in the wild only by other Vaurie's nightjars, rather than by humans. As a result, scientists do not know whether it is extinct, endangered, or even locally common.
