A small, very rare Hawaiian honeycreeper of remote native forests on Kauai. Declining rapidly; found only above 4,000 feet elevation in the eastern ‘Alaka’i Plateau. Gray above and whitish below with a pink bill and a short tail. Juveniles have white spectacles. Forages by creeping on branches, rarely in foliage. Its rarely-heard song is a high, even trill and the call is a soft “squeet.” Careful observations are needed to distinguish this species from other small honeycreepers.
