Extinct.\u00a0 Formerly endemic to the Big Island of Hawaii.<\/strong><\/p>

Known from koa forests between approximately 1,400 and 1,500 m elevation on the slopes of Pu\u2019u Hualalai.\u00a0 As its name suggests, it was associated with the koa tree (Acacia koa<\/em>) and is believed to have subsisted largely on the koa seed.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Identification<\/strong><\/span><\/p>

A medium-large olive grosbeak.<\/p>

Male had dark-olive upperparts, a yellow head and breast, and yellowish-olive belly.<\/p>

Females and immatures were dark-olive above, with paler yellowish and grayish tones in their underparts.\u00a0 They were easily confused with the Greater <\/strong>Koa-Finch<\/strong><\/a>\u2014and were initially thought to belong to that species.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
