One of the largest and most spectacular pheasants in the world. Males have extraordinarily elongated secondary wing feathers covered in eye-like ocelli, displayed in a huge fanned circle during courtship on a cleared forest-floor 'dancing ground'. Females are much plainer, brown and cryptic.
Best detected by its far-carrying, two-note 'kwow-wow' call echoing through lowland forest at dawn and dusk, long before any visual sighting. Males maintain and defend a cleared display court for years, making these sites — when known to guides — a reliable place to wait quietly.
