The Bishop's ‘ō‘ō or Moloka‘i ‘ō‘ō (Moho bishopi), is a extinct species of ʻōʻō in the Mohoidae family. It was previously regarded as member of the Australo-Pacific honeyeaters (Meliphagidae). Lionel Walter Rothschild named it after Charles Reed Bishop, the founder of the Bishop Museum.


It was discovered in 1892 by Henry C. Palmer, a bird collector for Lord Rothschild. Its length was about 29 centimeters. The tail had reached a length of 10 centimeters. The plumage was general glossy black with yellow feather tufts on the maxillaries, beneath the wings and the undertail coverts. Their songs were simple two notes, took-took, which could be heard for miles.


It was endemic to the montane forests in the eastern of the Hawaiian Island of Molokai, and Mount Olokai. Subfossil bone finds are known from Maui, on Mount Olinda at about 4,500 ft above sea level.


Little is known about its ecology. It fed on nectar from the flowers of Hawaiian lobelioids.


Causes of the bird's extinction include deforestation, competition from introduced predators, hunting by the Hawaiians due to the much sought yellow feathers to create the precious capes for the nobility, and diseases which were introduced by mosquitoes. It was last seen in 1904 by ornithologist George Campbell Munro. In 1915 Munro tried to verify reports of eventual sightings but he never found this bird again. In 1981 there was an allegedly rediscovery on Maui although this sighting was never confirmed.


Today the bird can only be seen as specimens, paintings, picture notes, and skins. Records of these types are known to be held in Bremen, Cambridge, Massachusetts;. Honolulu; London; Molokai, Hawaiian Islands; New York; and Stockholm.
