Maui Parrotbill

Pseudonestor xanthophrys

The Maui Parrotbill (*Pseudonestor xanthophrys*) is a critically endangered Hawaiian honeycreeper, a vibrant and unique lineage of finches endemic to the Hawaiian Islands. This small, robust songbird measures about 14 cm (5.5 inches) in length and weighs 20-25 grams, characterized by its olive-green upperparts, bright yellow underparts, and a distinctive dark mask across its eyes.

Habitat

Found exclusively in high-elevation (1,200-2,000 meters) wet native forests dominated by ʻōhiʻa (Metrosideros polymorpha) and koa (Acacia koa) trees.

Diet

Primarily feeds on wood-boring insect larvae, especially from native trees, which it extracts using its uniquely structured bill. Nectar from ʻōhiʻa blossoms and small fruits are also consumed seasonally.
