The ʻōʻū (Psittirostra psittacea), is a species of Hawaiian honeycreeper, that is endemic to the Hawaiian islands. It has a dark green back and olive green underparts; males have a yellow head while females have a green head. Its unusual beak seems to be adapted to feeding on the fruits of Freycinetia arborea. It has a strong flight which it uses to fly considerably distances in search of this Hawaiian endemic vine, but will eat other fruits, buds, flowers and insects. Order: Passeriformes, Family: Fringillidae, Subfamily: Carduelinae, Tribe: Psittirostrini, Genus: Psittirostra, Species: Psittirostra psittacea (Gmelin, 1789)
