The Maui parrotbill or kiwikiu (Pseudonestor xanthophrys) is a species of Hawaiian honeycreeper, that is endemic to Maui in Hawaii. It can only be found in 50 square kilometres (19 sq mi) of mesic and wet forests at 1,200–2,150 metres (3,940–7,050 ft) on the windward slopes of Haleakalā. This species is critically endangered, with an estimated population of only 500 individuals. Fossil evidence indicates that the bird could at one time be seen in dry forests at elevations as low as 200–300 metres (660–980 ft), as well as on the island of Molokaʻi
