context_page_description: The black-billed sicklebill, also known as buff-tailed sicklebill, is a species of bird-of-paradise. It, along with its congener, are the only members of the genus Drepanornis.
context_section_description: Though they share similar features and the same English name, the Drepanornis sicklebills are only distantly related to the Epimachus sicklebills. In fact, they are more closely allied with the twelve-wired and standardwing birds-of-paradise. There are two agreeable subspecies, though races geisleri from the Huon Peninsula and inversus from the Weyland mountains and nearby highlands require more detail to be considered valid subspecies or not.
