Species Information

The oloma‘o is one of five species of Hawaiian solitaires (family: Turdidae). All adult Hawaiian solitaires have olive-brown and gray plumage. Oloma‘o are prolific singers often singing into the night, and the species engages in song flights. Their song, like that of many thrushes, is melodious. Similar to other Hawaiian solitaires, the species often trembles their wings when perched. Oloma‘o tend to stay or return to a particular site (philopatric), which result in rarely leaving their small home range. The species feeds on a variety of small fruits and insects. Little is known about their breeding biology, but it is presumed to be similar to the ‘ōma‘o (M. obscurus).

Distribution

Unknown. Probably extinct. The historic range included the native forests of eastern Moloka‘i and Lāna‘i. Historically the species also may have occurred on Maui, where subfossils of Hawaiian solitaires are abundant

Habitat

Unknown. Historically occupied closed, wet and mesic ‘ōhi‘a (Metrosideros polymorpha) forests across a broad elevation range. The areas where the species was last observed are managed by the State of Hawai‘i as a Natural Area Reserve or by private conservation entities (e.g., The Nature Conservancy).
