Oahu Elepaio
Chasiempis ibidis
The Oʻahu ʻelepaio (Chasiempis ibidis) is a monarch flycatcher found on the Hawaiian Island of Oahu.
This species looks very similar to the Hawaiʻi ʻelepaio, but the white underside extends to the flanks and further up the breast, and the upperside - especially the head - is more rust-colored.
