This species was formerly found in the Hawaiian Islands, USA, but it has not been recorded since 1981 and is now considered Extinct. Habitat loss was probably the primary cause of its decline.

Geographic Range [top]

Range Description:Moho bishopi was a forest bird endemic to the Hawaiian Islands, USA (Pratt et al. 1987). It was last recorded on Moloka'i in 1904 by Munro (1944), who received local reports of its survival until 1915, but could find no more birds despite numerous further searches up until 1949. There is very little historical information about its occurrence on Maui, and although a single bird believed to be this species was observed in 1981 on the north-east slope of Haleakala (Sabo 1982), there have been no further confirmed records despite intensive searching (Collar et al. 1994) and the species is presumed extinct (Reynolds and Snetsinger 2001).

Threats [top]

Major Threat(s): Habitat destruction caused by conversion to agriculture and grazing by feral mammals inevitably initiated the species's decline, with introduced black rat Rattus rattus and the spread of disease carried by introduced mosquitoes blamed for the population crash early in the 20th century (Pratt 1994).
