The Chuuk Monarch is endemic to the Chuuk Islands. Baker’s 1951 account describes a mostly white male with a black face and throat and a mostly sooty-black female. The species uses large patches of primary forest and mangroves.
Baker described the male as mostly white, with a black forehead, lores, chin, and throat; the chin and throat had a blue gloss, and the primary tips were black. Females were generally sooty black and darker above, with some individuals showing white patches beneath the tail or on the rump.
It occurs on the high lagoon islands of Chuuk and some outer-reef islets, using large patches of primary forest and large mangrove stands.
