Akikiki

About Akikiki

ʻAkikiki, also called the Kauaʻi creeper, is a small Hawaiian honeycreeper found naturally only on Kauaʻi. Adults are subdued gray to olive-brown above and paler below, with a short, slightly curved bill adapted to picking tiny prey from bark and foliage. Males and females look much alike. Rather than relying on bright plumage, the bird is recognized by its active, deliberate climbing movements as it works over trunks, branches, and twigs in the manner of a nuthatch or treecreeper.

The species is an arboreal insectivore of native wet montane forest. It searches living and dead wood, bark crevices, moss, lichens, and leaf surfaces for beetles, caterpillars, spiders, and other small arthropods, sometimes hanging at unusual angles to inspect the underside of a branch. ʻAkikiki often traveled in pairs, family groups, or mixed-species flocks. Its last wild stronghold was the high-elevation ʻōhiʻa-dominated forest of the Alakaʻi Plateau, where cool conditions once limited the mosquitoes that transmit avian malaria.

Wild nesting was documented mainly from March through June. Both members of a pair helped build a compact open-cup nest of moss, lichen, bark, and plant fibers high in an ʻōhiʻa tree; the female performed incubation while both parents fed nestlings and dependent fledglings. Documented clutches generally contained two eggs. Young remained with their parents for an extended period, and pairs were thought usually to raise only one brood in a season. A dependable maximum lifespan has not been established for the species.

ʻAkikiki is federally and state listed as endangered and is now considered functionally extinct in the wild, although a managed conservation population survives under human care. Mosquito-borne avian malaria drove the most recent collapse as warming temperatures allowed mosquitoes to reach former high-elevation refuges. Habitat degradation, hurricanes, invasive plants and ungulates, introduced predators, and very small population size compound the danger. Preventing extinction now depends on conservation breeding, disease control, and the eventual restoration of safe native forest on Kauaʻi.
