CONSERVATION STATUS

Vulnerable

The Omao has a very small range that is limited to the island of Hawaii within the Hawaiian Islands. This bird prefers moist subtropical and tropical forest and shrubland ecosystems as well as dry savannas, and has been known to reside on plantations. The population of the bird has not been determined precisely but is thought to exceed late 1970’s estimates of around 170,000, partly due to the disease resistance of the species. While the Omao is plentiful in number, its limited range of habitat places it within the criteria for the IUCN Red List and it currently has an evaluation level of Vulnerable.
