A distinctive large, plump, short-tailed, long-legged forest bird with a black upperside and white underside, a striking red area on the lower belly, and a conspicuous silvery-blue shoulder patch. Juvenile duller, with buff on underparts. Shy, more often heard than seen. Usually found singly or in pairs in humid lowland and hill forest. Forages on the ground, but while calling often perches high in the understory or canopy. Very vocal; frequently given song is a mournful wolf whistle.
