The olomaʻo (Myadestes lanaiensis) is a small, dark solitaire endemic to Maui, Lānaʻi and Molokaʻi in the Hawaiian Islands, and is a bird which probably is extinct. It grows up to 7 inches in length. The male and female of the species look similar. It is dark brown above and gray below with blackish legs. It is closely related to the other species of Hawaiian thrushes, the puaiohi (M. palmeri), ʻōmaʻo (M. obscurus), and probably extinct kāmaʻo (M. myadestinus).
