Useful to know

The Mussau monarch is an island-endemic flycatcher confined to the St Matthias Islands of Papua New Guinea, primarily Mussau Island. It was formerly placed in the genus Monarcha but is now in Symposiachrus. It favors intact lowland forest but can persist in lightly disturbed areas and rural gardens. Ongoing logging and forest clearance are its main threats.
