Chasiempis

thumb|Illustration by Joseph Smit The elepaio are three species of monarch flycatcher in the genus Chasiempis. They are endemic to the Hawaiian Islands, 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 Hawaii, no subspecies have yet become extinct, though two have become quite rare.
