Species Information
Black mamo, also known as ‘Ō’ō nuku umu is an extinct Hawaiian honeycreeper. The dark coloration of black mamo is unusual foliage for honeycreepers (Amadon 1986). Hawaiian Honeycreepers are typically noted as haivng orange, yellow and red foliage. Native Hawaiians commonly used the feathers of honeycreeprs to make robes, to inclue the ‘Ō’ō (Amadon 1986). The process of defeathering these species contributed to their population decline. As observed in other honeycreepers, the long and narrow curved beak of the Black Mamo matches with specific fruit trees. Specifically, the Black Mamo’s beak fits with aborescent lobelioids flowers (Pratt 2005). This adaptation alludes to their food source. The last known sighting of this Honeycreeper was in Molokai, 1907.
Distribution
Molokai
Habitat
Black mamo preferrerd the fruits found in small trees and shrubs, such as Hawaiian lobeliads (Perkins 1903). This food source was found in high elevation forests (Banko 1979).
Threats
Although the exact cause of extinction is uncertain, the Black Mamo was likely were susceptible to the same factors that threaten other native Hawaiian forest birds including loss and degradation of habitat, predation by introduced mammals, and disease.
