The elepaios are three species of monarch flycatcher in the genus ''Chasiempis''. They are endemic to Hawaii and were formerly considered conspecific. They measure 14 cm long and weigh 12–18 g. One species inhabits the Big Island, another Oahu and the third Kauai. Being one of the most adaptable native birds of the archipelago, no subspecies have yet become extinct, though two have become quite rare. The elepaio is the first native bird to sing in the morning and the last to stop singing at night; apart from whistled and chattering contact and alarm calls, it is probably best known for its song, from which derives the common name: a pleasant and rather loud warble which sounds like ''e-le-PAI-o'' or ''ele-PAI-o''. It nests between January and June. The species are: *Hawaiʻi ʻelepaio, ''Chasiempis sandwichensis'' *O'ahu ʻelepaio, ''Chasiempis ibidis'' *Kauaʻi ʻelepaio, ''Chasiempis sclateri'' ==Distribution== Uniquely among Hawaiian passerines, the distribution of the elepaio is peculiarly discontinuous. It does not – and judging from the lack of fossil remains, apparently never did – occur on Maui Nui or its successor islands. If this assumption is correct, the reasons are unknown at present. However, the strange "flycatcher finches", extinct honeycreepers of the genus ''Vangulifer'', are only known to have inhabited Maui and probably evolved on Maui Nui.〔 There, they probably filled the same ecological niche as the elepaio did on the other islands. Competition from ''Vangulifer'' may thus have prevented a successful colonization of Maui Nui by ''Chasiempis''. 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「‘Elepaio」の詳細全文を読む スポンサード リンク
