A sturdy songbird with fairly long tail and substantial bill. Glossy black above, bright white below. Female may show buffy patch on upper breast. Similar to Paperbark Flycatcher; best identified by range. Inhabits open woodland and wetland areas, usually forages near the ground. Compare Willie Wagtail. Calls loudly with a clear whistled "tui-tui-tui” and an incomparable buzzing scissors-grinder sound.
