Maui Parrotbills live as long as 16 years, choosing a single mate and remaining loyal throughout their lives. Reproducing slowly, usually producing only a single chick every year or two, the young birds mature slowly, too. Immature birds remain with their parents from five months to over a year.
True to its name, the Maui Parrotbill has a heavy, specialized bill. It’s used to split branches and extract insect larvae, the bird’s primary prey.
