Lanai Hookbill

Dysmorodrepanis munroi

The Lānaʻi hookbill (Dysmorodrepanis munroi) is an extinct species of Hawaiian honeycreeper. It was endemic to the island of Lānaʻi in Hawaiʻi, and was last seen in the southwestern part of the island. George C. Munro collected the only known specimen of this species in 1913, which is housed in the Bernice P. Bishop Museum in Honolulu, and saw the species only twice more, once in 1916 and for a final time in 1918. No other sightings have been reported. They inhabited montane dry forests dominated by ʻakoko (Euphorbia species) and ōpuhe (Urera glabra). The Lānaʻi hookbill was monotypic within the genus Dysmorodrepanis and had no known subspecies. Its closest relative is believed to be the ʻōʻū, and some early authors suggested that the Lānaʻi hookbill was merely a deformed ʻōʻū. The Lānaʻi hookbill was a plump, medium-sized bird with greenish olive upperparts and pale whitish yellow underparts. It also had a yellow or white superciliary line and a white chin and throat. The wings also had a distinctive and conspicuous white wing patch. The hookbill's distinguishing characteristic was its heavy, parrotlike bill, which had the mandibles hooking sharply towards each other, leaving a gap between them when the beak was closed.
