Ou ( Psittirostra psittacea )
Abstract
The ‘Ö‘ü and the Läna‘i Hookbill are plump, predominantly olive green, thick-billed Hawaiian honeycreepers. The ‘Ö‘ü is now very rare and restricted to remote, high-elevation native forest, and the Läna‘i Hookbill is extinct. They are closely related species, belonging to a specialized tribe, Psittirostrini, consisting of nine historically known Hawaiian species with heavy, finchlike to parrotlike bills. Because of their taxonomic affinity and the paucity of information on the Läna‘i Hookbill, we are treating the two species in a single account.
