General

Omao: AKA Hawaiian Thrush or Hawaiian Solitaire; most common of the Hawaiian thrushes, rather drab, dark gray-brown upperparts and pale gray underparts with brown edging on wings; gray-brown head with pale stippling from lores to ear coverts. Bill is short and dark. Eyes are dark and legs are dark gray-black. Sexes are similar. Juvenile has a more brown back with a scalloped gray-brown pattern on underparts with white-buff on wings, breast and upperparts.

Range and Habitat

Oma'o: This resident species is endemic only to Hawaii and is found primarily along the eastern and southeastern slopes of the Big Island above 3,200' above sea level. Their preferred habitat is rainforest, but they may sometimes be found in the savannahs and in the high elevation scrub of Mauna Loa.

Breeding and Nesting

Oma'o: One or two gray-white to tan eggs with red-brown to lavender splotches and markings are laid in a tree cavity, tree fern, lava tube, or ledge. A loose cup-shaped nest is made of ferns, mosses, leaves, and twigs. Female incubates eggs for 15-17 days, chicks fledge 17-21 days after hatching.

Foraging and Feeding

Omao: They have a mixed diet of fruit, flower parts and invertebrates, including caterpillars, spiders, beetles, true bugs, land snails and leaf-hoppers. They forage on or near the ground in the understory. They feed primarily from perches; they also frequently use aerial maneuvers when foraging for both fruits and arthropods. They swallow the majority of their fruits whole.

Vocalization

Oma'o: Voice is a jerky series of slurred flute-like "whip-per-weeo-whip-per-weet” notes and a shrill whistle.

Similar Species
