Viridonia sagittirostris
The Greater Amakihi, scientific name *Viridonia sagittirostris*, was a striking and unique member of the Hawaiian honeycreeper family, sadly now extinct. Averaging approximately 14-15 cm (5.5-6 inches) in length, it displayed a vibrant olive-green plumage on its back, transitioning to yellowish-green on its underparts, with darker wings and tail. Its most distinctive field mark was its remarkably long, straight, heavy, and sharply pointed bill, which gave it its species epithet 'sagittirostri...
This species was restricted to high-elevation, wet montane forests, primarily dominated by 'ōhi'a (Metrosideros polymorpha) and koa (Acacia koa) trees, typically above 1,200 meters (4,000 feet) on the windward slopes of Hawaiʻi Island.
Its diet consisted primarily of nectar, especially from native 'ōhi'a lehua blossoms, supplemented significantly by insects and spiders gleaned from bark, foliage, and perhaps probed from wood.
Due to its early extinction, detailed behavioral observations of the Greater Amakihi are scarce. It was likely a diurnal species, active during the day, foraging among the canopy and understory of native forests. Its unique, straight bill suggests a specialized foraging technique, possibly probin...
Historically, the Greater Amakihi was strictly endemic to the island of Hawaiʻi, with its entire known distribution confined to specific ecological zones. It inhabited the high-elevation montane wet forests, predominantly found on the windward slopes of the island's massive volcanoes, Mauna Kea a...

- The scientific name 'sagittirostris' directly translates to 'arrow-billed,' a perfect description of its unique, straight, pointed beak. - It was endemic to only one Hawaiian island, Hawaiʻi, making its range incredibly restricted and vulnerable. - The last definitive observation of the Greater...
