The eared nightjars are a small group of nocturnal birds in the nightjar family, although the taxonomy is uncertain. There are seven species, mainly found in forest and scrub from China to Australia. 5 species are placed in the genus, ''Eurostopodus'', the other two species in ''Lyncornis''. They are long winged birds with plumage patterned with grey and brown to camouflage them when resting on the ground. They feed on insects caught in flight. A single white egg is laid directly on the ground and incubated by both adults. The chicks can walk soon after hatching. ==Taxonomy== The order Caprimulgiformes contains several families of nocturnal insectivores, these are the frogmouths, the potoos, the oilbird and the nightjars. The latter family is normally split into two subfamilies, the American nighthawks, Chordelinae, and the typical nightjars Caprimulginae.〔Cleere (1998) p. 15〕 The eared nightjars are sometimes considered a subfamily Eurostopodinae of the Caprimulgidae but some studies have them as a sister group, while others treat them as a clade within the caprimulgids; others consider that the genus ''Eurostopodus'' may not be monophyletic.〔Kin-Lan Han, M.S. (2006) ''(Molecular systematics of nightjars and nighthawks (Caprimulgidae) )'' MS Thesis. University of Maryland〕 The eared nightjars consist of seven extant species in two genera, ''Eurostopodus'' and ''Lyncornis'': *''Eurostopodus'' * *Archbold's nightjar, ''Eurostopodus archboldi'' * *Spotted nightjar, ''Eurostopodus argus'' * *Satanic nightjar, ''Eurostopodus diabolicus'' * *White-throated nightjar, ''Eurostopodus mystacalis'' * *New Caledonian white-throated nightjar, ''Eurostopodus (mystacalis) exsul'' - possibly extinct (mid-20th century) * *Papuan nightjar, ''Eurostopodus papuensis'' *''Lyncornis'' * *Malaysian eared nightjar, ''Lyncornis temminckii'' * *Great eared nightjar, ''Lyncornis macrotis'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「eared nightjar」の詳細全文を読む スポンサード リンク
