Justification of Red List category
This species was known from the Hawaiian island of Hawai'i, USA, but it has not been recorded since 1892 and is now Extinct. Habitat destruction, invasive species and avian disease are likely to have caused the loss of this species.
Population justification
None remain.
Trend justification
The species was already very rare when discovered, being restricted to only about four square miles, and was last collected in 1892 (Greenway 1967, Hume 2017).
Chloridops kona was endemic to Hawai'i, USA (Stattersfield et al. 1998). The genus is known from fossils from Kaua'i, O`ahu and Maui (James and Olson 1991).
It inhabited naio forest on lava flows at 1,100-1,700 m, and fed on seeds (Banko and Banko 2009, Hume 2017).
Reasons for its extinction are unknown though habitat destruction for logging and agriculture, introduced species and avian disease are likely to have been responsible (Grant 1995, Hume 2017).
