This enormous, sociable, ground-loving hornbill is easily recognized. The adult male has an extensive brilliant red face and throat wattles, while the adult female has purple-blue skin in the center of the red throat patch. The immature is scruffy with yellowish facial skin. In flight, this huge bird is black with extensive white wingtips. Family groups walk slowly through bushy savanna and grassland, foraging for large invertebrates and small vertebrates. In the early morning, dominant pairs duet with a deep-bass booming, “oooh..oooh..ooh-oh”, which can be heard several kilometers away.
