奥亚吸蜜鸟（Moho braccatus）是可爱岛特有及已灭绝的吸蜜鸟。牠们在20世纪初的亚热带森林甚为普遍，但自此数量就开始下降。1987年仍有听到牠们的歌声，但之后就被认为是已灭绝。灭绝的原因包括黑鼠、猪和带有鸟类疾病的蚊入侵，以及栖息地的破坏。

奥亚吸蜜鸟是夏威夷最细小的吸蜜鸟之一，只有约20厘米长。牠们呈黑色或深褐色，脚上有稀疏的黄色羽毛，胸部及翼下有白带。牠们的喙尖锐及稍微弯曲，可以抽出花蜜。牠们特别喜欢山梗菜属及桃金娘的花蜜，也会吃细小的无脊椎动物及果实。

奥亚吸蜜鸟在可爱岛峡谷的树孔中筑巢。牠们的近亲如夏威夷吸蜜鸟、监督吸蜜鸟及欧胡吸蜜鸟都已灭绝。对于奥亚吸蜜鸟所知有限。牠们的灭绝涉及复杂的问题，包括了蚊子散播疾病，令牠们退到较高的地方居住，但在较高的地方却缺乏树孔筑巢。另外在十年间曾发生两次飓风侵袭，将大部份有树孔的古树都破坏了，第二个飓风的到来亦阻碍了树木的生长，引致牠们于1987年灭绝。

The Kauaʻi ʻōʻō or ʻōʻōʻāʻā (Moho braccatus) is a member of the extinct genus of the ʻōʻōs (Moho) within the extinct family Mohoidae from the islands of Hawai'i. It was previously regarded as member of the Australo-Pacific honeyeaters (Meliphagidae). This bird was endemic to the island of Kauaʻi. It was common in the subtropical forests of the island until the early twentieth century, when its decline began. Its song was last heard in 1987 and it has since been declared extinct. The causes of its extinction include the introduction of the Polynesian rat, domestic pig, and mosquitoes carrying avian disease (avian malaria and avian pox), as well as habitat destruction.
