The Oahu Elepaio is a small flycatcher found only on Oahu. Hawaiʻi and U.S. federal listings classify it as endangered.
It is dark brown above and white below, sometimes with pale breast streaks. White wing bars, tail tips, and throat are conspicuous.
On Oahu it forages in native and non-native trees. Pairs often remain together throughout the year.
