Psittirostra psittacea

The ʻōʻū is an extinct species of Hawaiian honeycreeper that was endemic to the Hawaiian islands. It had a dark green back and olive green underparts; males had a yellow head while females had a green head. Its unusual beak seems to have been adapted to feeding on the fruits of Freycinetia arborea. It had a strong flight which it used to fly considerable distances in search of this vine, but it also ate other fruits, buds, flowers and insects.
