The Kauaʻi ʻōʻō or ʻōʻōʻāʻā (Moho braccatus) was the last member of the ʻōʻō (Moho) genus within the Mohoidae family of birds from the islands of Hawaiʻi. The entire family is now extinct. It was previously regarded as a member of the Australo-Pacific honeyeaters (family Meliphagidae). It was the last surviving member of the Mohoidae, which had originated over 15-20 million years prior during the Miocene, with the Kauaʻi ʻōʻō's extinction marking the only extinction of an entire avian family in modern times ("modern" meaning post-1500 AD).
