Typical Environment

Occurs on Mussau Island, where it inhabits lowland primary and semi-mature secondary rainforests. It uses forest interiors, edges, and occasionally tall agroforestry mosaics if canopy structure remains. Forages from the mid-story to subcanopy, often making short sallies to catch aerial insects. Sensitive to heavy logging and widespread clearing, so it is most frequent in less disturbed tracts.

Useful to know

Also known as the Mussau monarch, this insect-eating songbird is confined to Mussau in Papua New Guinea's St Matthias group. It favors intact lowland rainforest but can persist in lightly disturbed forest, making canopy sallies for prey. Ongoing logging and habitat conversion threaten its small range. Protection of primary forest patches is critical for its long-term survival.
