Mamo

Mamo or woowoo is a common name for two species of extinct birds. Together with the extant ʻIʻiwi they make up the genus Drepanis. These nectarivorous finches were endemic to Hawaii but are now extinct. The Hawaiian name may be related to the name of the ʻōʻō (Moho nobilis), a bird with a similar appearance. Another name for the mamo was ʻōʻō-nuku-umu, meaning "ʻōʻō with the sucking beak". Two species are known.
