It is only known from five specimens, in Harvard, Honolulu, New York and Tring (Greenway 1967), the latter with two (Knox and Walters 1994), and a possible sight record in 1937 (Munro 1944). Fossils of the genus have been found on Kaua'i, Moloka'i and O'ahu (James and Olson 1991). The last specimen was collected in 1892 (Greenway 1967).

Threats [top]

Major Threat(s):	Nothing is known about the causes of its extinction (Greenway 1967), although deforestation and avian malaria are likely to have been contributing factors. Habitat change may have exposed the population to unusually high numbers of rats (W.E. Banko and P.C. Banko 2009).
