Population justification
None remain.

Distribution and population

Hemignathus sagittirostris was only found along the Wailuku river above Hilo on Hawai`i, USA (Lindsey et al. 1998). It was discovered in 1892 (Greenway 1967), and last recorded in 1901 (Stattersfield et al. 1998).


It was restricted to dense, moist ohi'a forest at 152-1220 m.


This forest was cleared for sugar cane, causing the species's extinction (Amadon 1950).
