CONSERVATION STATUS

Endangered

The Oahu Elepaio is restricted to two mountain ranges on the Hawaiian island of Oahu. It occurs in mesic forests with a tall canopy and dense understory between 1,625 and 2,775 feet in the Waianae Mountains and between 325 and 1,800 feet in the southern Koolau Mountains. It forages for invertebrates by gleaning them from vegetation and catching them in flight. The Oahu Elepaio is believed to have a population of just 1,400 individuals and has been given a conservation rating of Endangered by the IUCN. It is threatened by introduced Black Rats preying on nesting females, naturally low productivity, diseases such as avian pox and avian malaria, and fires that could destroy its limited habitat.

INTERESTING FACTS

  • A group of flycatchers has many collective nouns, including an "outfield", "swatting", "zapper", and "zipper" of flycatchers.
  • It is considered the guardian spirit of canoe makers, who noticed that Koa trees frequented by these birds often harbored large insect populations that would make them unsuited for use as a canoe.
  • It is the first native bird to sing in the morning. Its song was thought to warn night spirits that dawn was approaching and their work must end.
  • The Elepaio was named by the ancient Hawaiians after the sound of its song.
