Wields two beaks in one: a chisel below, a probe above. The Swiss Army knife of Hawaiian couriers.
- Populasi
- ~1,900 individuals (~1,300 mature), decreasing
- Habitat
- Old-growth mesic and wet koa and ʻōhiʻa forest between roughly 1,300–2,100 m elevation
- Fakta menarik
- The ʻakiapōlāʻau has a strikingly asymmetrical bill — a short, straight lower mandible used to hammer and crush bark woodpecker-style, paired with a long, curved upper mandible used to probe and hook insects out of the holes it makes — letting it fill Hawaiʻi's woodpecker niche even though true woodpeckers never reached the islands.
- Sebaran
- Endemic to the island of Hawaiʻi (the Big Island) only, restricted to two disjunct subpopulations (Hāmākua/Hilo and Kaʻū); formerly more widespread, extirpated from Mauna Kea and likely Kona
- Makanan
- Primarily lepidopteran and cerambycid beetle larvae excavated from bark and wood using its unique bill, plus tree sap (fed on year-round) and some nectar
