Geographic Range [top]

Range Description:Moho braccatus was endemic to Kaua'i, Hawaii, USA. It was common in the 1890s, but declined drastically during the early 20th century (Pratt et al. 1987). By the 1970s, it was confined to the Alaka'i Wilderness Preserve (Pratt 1994). In 1981, a single pair remained, the female of which was not found after Hurricane Iwa in 1982, the male being last seen in 1985. The last report, of vocalisations only, was in 1987, and the species has not been recorded during subsequent surveys of Alaka'i (Conant et al. 1998).
