 Ruppell’s korhaans are usually found in pairs or small family groups and are omnivorous feeders, eating insects, small reptiles and vegetable matter.  They feed while walking slowly forward and peck at the ground ahead of their feet.  Their call is a deep, frog-like croak, usually taking the form of a duet.
