This Hawaiian honeycreeper lives in high-elevation native forest on Kauai. It uses its curved bill to search trunks and branches for insects and also feeds on nectar and fruit.
Males are olive above and yellowish below, with dark lores and a pale, strongly curved bill. Females are duller and have a smaller bill.
It gleans insects from trunks, branches and leaves and pries hidden prey from crevices. It also takes nectar and fruit, sometimes piercing the base of longer flowers to sip leaking nectar.
