The Maui nukupuʻu is a species of nukupuʻu Hawaiian honeycreeper that was endemic to the island of Maui in the Hawaiian Islands. The small, five-inch-long bird lived only in eastern Maui, where it was dependent on high-elevation mesic and wet forests of ʻōhiʻa lehua and koa. These two species of trees attract insects, causing the Maui nukupuʻu to have a higher chance of finding a meal near these trees. It was last sighted in the late 1990's, and is most likely extinct.
