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
ʻElepaio is a bimonthly peer-reviewed scientific journal published by the Hawaii Audubon Society (the Hawaii chapter of the National Audubon Society). It is named after a small Hawaiian bird. The journal was established in 1939.
