The poʻo-uli (Melamprosops phaeosoma), or black-faced honeycreeper, is a species of passerine bird that is endemic to the island of Maui in Hawaiʻi. It is considered to be a member of the Hawaiian honeycreepers, and is the only member of its genus Melamprosops. It has a black head, brown upper parts and pale grey underparts. This bird is only known from the drier, easternmost side of Maui, and has decreased in numbers so that now only a few individuals, if any, remain. With extinction threatening, efforts have been made to capture birds to enable them to breed in captivity. This has been largely unsuccessful, and in 2004, only two known birds remained, and since then, no further birds have been sighted.
