Mohoidae

The kioea or kiowea (Chaetoptila angustipluma) is an extinct species of Hawaiian honeyeater that was endemic to the islands of Hawaii before going extinct around the mid-19th century.

Mohoidae, also known as the Hawaiian honeyeaters, is a family of Hawaiian species of now recently extinct, nectarivorous songbirds in the genera Moho (ōō) and Chaetoptila (kioea). These now extinct birds form their own family, representing the only complete extinction of an entire avian family in modern times, when the disputed family Turnagridae is regarded as invalid. The last surviving species in the family, the Kauaʻi ʻōʻō (Moho braccatus), became extinct after 1987.
