The Acrocephalus familiaris kingi (scientific name) or nihoa millerbird is endemic to the Nihoa Island, Hawaiian Islands. Only 5 inches in length, this bird has dark sepia wings, a white under body and short dark beak. They are extremely shy and spend most of their time near the forest floor, foraging for insects, which constitute a major portion of their diet. In fact, it is named the millerbird, because of its favourite food, the miller moth. An average clutch has 2 eggs laid in nests constructed out of grass stems and concealed in shrubs. The incubation period is approximately 25 days. In the last 30 years, the number of nihoa millerbirds has fluctuated between 300 to 700. Its IUCN listing is CRITICALLY ENDANGERED.
