Abbott’s duiker.

Abbott's duiker (Cephalophus spadix), also known as minde in swahili, is a large, forest-dwelling duiker (small antelope) found only in a few scattered enclaves in Tanzania. It may be a subspecies of the yellow backed duiker. It is very rare and the first photograph was taken as recently as 2003.
 Abbott's duikers stand around 65 cm (26 in) tall at the shoulder and weigh about 55 kg (121 lb). 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 (8 to 12 cm (3.1 to 4.7 in)).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 pythons (Python species), while duikers of all ages may fall victim to leopards (Panthera pardus). Lions (Panthera leo) and spotted hyenas (Crocuta crocuta) may also hunt this duiker species in some areas.
