crnokapa trnokljunka Origma murina

A small, secretive bird of lowland and foothill forest understory. Rusty underparts, gray-brown back blending to a blackish front half of the crown, white chin and upper throat. Aru birds are more white below. Similar to Bicolored Mouse-Warbler, but Rusty is usually found lower and has a white rather than rufous throat. Much more often heard than seen and it is one of the characteristic sounds of the forest. A slightly tuneless, high-pitched, whistled song.
