- Habitat loss
- Mortality through predation and diseases
The Maui Parrotbill is a very rare kiwikiu species that can only be found within the 50 square kilometre range of undisturbed mesic forest within the island of Maui in Hawaii. This insect-eating Hawaiian honeycreeper has a distinct ‘chip’ call which it emits every three to five seconds. A strictly monogamous bird species, it only breeds a single nestling every season, between November and June.
Much of the native habitat of the Maui Parrotbill have been altered or destroyed due to timber production, agricultural activities, and livestock businesses. The limited habitat is also subject to competition with other bird species and insects.
The Maui Parrotbill is vulnerable to being caught and killed by feral pigs and other ungulates; its eggs and young are easy targets for rats and owls; and both young and adult birds can easily succumb to malaria and other mosquito-borne diseases.
