An unmistakable, large ground bird with iridescent blue plumage. The unmistakable male spreads out its ornamental upper tail feathers when courting females. Females have a shorter tail and browner plumage. Found in forest, forest edge, and agricultural land. Often seen on paths or alertly feeding in the undergrowth. Can be fairly confiding especially when found close to human habitation. Its loud screaming “may-yow” calls are heard incessantly during the rainy season. Hawaii: introduced and widely established on the western side of Hawaii Island and locally in Waianae Mountains of Oahu and southern Maui.
