The Molokai thrush or olomao is a medium sized solitaire with olive-brown upper parts, grayish white underparts, and a buffy patch at the base of the primaries. The bill and legs are dark. Juveniles exhibit the same scalloped plumage as other young native thrushes; i.e., omao (Myadestes obscurus) and puaiohi or small Kauai thrush (Mydadestes palmeri) (USFWS 2006, p. 2-26). The Molokai thrush is about 21 centimeters (8.3 inches) in length. Differences between the sexes and between adults and young have not been studied in detail, nor has molt, but may be similar to those of the closely related omao (M. obscurus) on Hawaii Island. In that species, males are larger than females on average, and birds in first basic plumage usually retain juvenile scalloping in the wing coverts (Fancy et al. 1994). Omao molt from June through November (Ralph and Fancy 1994b). Much like the related omao, olomao live solitarily or in pairs and seldom leave their small home range (Bryan 1908, Ralph and Fancy 1994b). They do not make long flights over the canopy, but rise above the trees during song flights (Bryan 1908). Like other Hawaiian solitaires, they often tremble their wings when perched (Rothschild 1893 to 1900, Perkins 1903, Bryan 1908).
