Omao

Myadestes obscurus

The Omao is a medium-sized Hawaiian thrush endemic to the Big Island, characterized by its inconspicuous gray-brown plumage and complex vocalizations. It is the most abundant of the surviving native Hawaiian thrushes and plays a crucial role in forest seed dispersal.

Field notes

  • It is a primary seed disperser for native plants, feeding heavily on the fruits of the 'ōlapa and pilo trees.
  • The species exhibits a unique wing-quivering behavior while perched, often seen during social displays or vocalizing.
  • Unlike many other native Hawaiian birds, the Omao shows a degree of resistance to avian malaria, allowing it to persist in some lower-elevation habitats.
  • It is closely related to the Townsend’s Solitaire, representing a colonization event from North America by the Myadestes genus.
  • The Omao is currently the only native thrush species on the Big Island following the extinction of its relative, the Kamao, on Kauai.
Habitat
Montane rainforests and high-elevation mesic forests, particularly those dominated by 'ōhi'a and koa trees.
