Animalia > Chordata > Aves > Passeriformes > Turdidae > Myadestes > Myadestes obscurusMyadestes obscurus (Omao; 'Oma'o)Synonyms: Muscicapa obscura (homotypic); Phaeornis obscurus The ʻōmaʻo (Myadestes obscurus, also called the Hawaiian thrush) is an endemic species of robin-like bird found only on the island of Hawaii. ‘Ōma’o are closely related to the other endemic thrushes of the Hawaiian Islands, the kāmaʻo, the olomaʻo, and the puaiohi. ‘Ōma’o are found primarily in rainforests in the eastern and southeastern regions of the Big Island. Population estimates approximate 170,000 birds, making it the most common of the Hawaiian thrushes. It appears to have a stable population, but because the entire population exists on a small range and is endemic to a single island, it is considered vulnerable. |
