MERLIN提供

A distinctive black-and-white crow that occurs within the canopy of hill and mountain forest on Sulawesi and satellite islands. White parts of adults are duller on juveniles. Typically found in pairs or small groups. Gives a variety of conspicuous loud calls, including screeches, metallic whistles, and piping notes, very unlike traditional crow sounds.
