Waterfall-draped mountains encircle Hanalei National Wildlife Refuge on the Hawaiian island of Kaua’i. The winding Hanalei River feeds wetlands that are home to five endangered water birds: the koloa maoli (Hawaiian duck), the ‘alae ke‘oke‘o (Hawaiian coot), the ‘alae‘ula (Hawaiian moorhen), the ae‘o (Hawaiian stilt), and the nēnē (Hawaiian goose).
