Monarque de Truk Metabolus rugensis

Medium-sized flycatcher-like bird with a long pointed bill. Male is bright white with a black face and throat. Female is entirely dark overall. Juvenile is rufous above and paler buff below. Endemic to the Chuuk Islands of Micronesia, where it primarily inhabits remnant upland native forest, extensive mangroves, and small forested atolls. Less frequently in degraded lowland forest. Favors areas with a dense understory, where it forages singly or in small groups, moving slowly through the foliage. Sparse and declining as a result of habitat loss. Gives low whistles and a nasal “jeer!”
