Characteristics

Abbott's duikers stand around tall at the shoulder and weigh about . This duiker has a glossy, dark brown coat which is lighter on the underside. The face is paler and gray in color, with a large red tuft on the forehead; the horns are thin and short (). The secretive behavior of Abbott's duiker, along with its largely nocturnal habits and preference for dense vegetation, means little is known about the ecology and behavior of this species. It has been observed feeding on leaves in the forest understory, and on vegetation in forest clearings, and may feed on fruits, flowers and moss. An Abbott's duiker has also been seen with a frog in its mouth; duikers are known to occasionally capture and feed on live prey. The cryptic habits and alertness of Abbott's duiker unfortunately does not protect it entirely from predation. Young Abbott's duikers are probably preyed on by African crowned eagles (''Stephanoetus coronatus'') and

Less than 1,500 Abbott's duiker are estimated to be left in the world, with no captive population. They are threatened by
