The black magpie is a lowland forest bird from southeast Asia likely to be in the family Corvidae but difficult to place. Its heavy black body suggests a crow. Its upcurving nasal bristles (and a short crest in the Borneo subspecies) and general form suggest a jay. Its longer tail hints at magpie or treepie. A social bird, it forages in small groups in the canopy on fruits, invertebrates and small mammals. It has a varied vocal repertoire including mimicry, magpie-like chattering, and both hoarse and ringing notes.
