Large, odd-looking, charismatic terrestrial species with a small head, long legs, and almost no tail. Body is mostly black, with wing colors varying geographically from green in the west to black in the east. Usually seen in areas of well-protected humid forest and often encountered in noisy groups; usually runs away when discovered. May attend ant-swarms. Song is a loud hum, and calls when agitated are angry, cackling “tset” notes.
