), but is otherwise similar in general form. The legs are relatively short and sturdy, and the neck is thick. Overall color is a dark chestnut brown or black, becoming darker and more intense towards the hindquarters. There is a thin dorsal stripe faintly darker than the rest of the coat. The belly, lower flanks, and insides of the legs are paler brown than the back, occasionally with a reddish hue. A small pale gray patch may be present on the back near the base of the tail. The tail lacks a terminal tuft of hair. The face and throat are grayish-white except for the dark brown forehead and the bright white upper lip. A prominent bushy crest at the top of the head is one of the most distinctive characters of Abbotts Duiker. The crest extends well past the horns in some specimens, and may range in color from dark brown or maroon to bright rufous. The ears are rounded, pale brown outside and even paler inside. Horns are present in both sexes; they are long, thin, and slender, and lack conspicuous thickening at their base. Reported horn lengths are 8-12 cm. Dental formulais10/3,C0/1,P 3/3, M 3/3 (x2) = 32.

No detailed dietary studies have been conducted. Abbotts Duiker is thought to be mainly frugivorous, although the diet may also include flowers, green shoots, and herbage. It has been recorded feeding on the leaves of balsam (/mpatiens elegantissima), as well as plucking green moss from rocks. A camera-trap in the Udzungwa Mountains photographed an Abbotts Duiker holding an amphibian in its mouth, suggesting that it, like other duiker species, eats animal matter.

There is very little specific information available for this species. Infants have been recorded in September—October, but it is possible that the species breeds throughout the year. Reproductive parameters are likely similar to those of the Western Yellow-backed Duiker.

Presumed to be solitary. Pathways through dense habitat are regularly used, and hunters set snares along such paths to capture this species. Although generally retiring, Abbotts Duiker has been known to kill dogs if cornered with no means of escape. If pressed, individuals may take to water when fleeing from a threat.

Classified as Endangered on The IUCN Red List. Its distribution is extremely restricted and fragmented, making Abbotts Duiker vulnerable to habitat loss and degradation as a result of logging and human settlement. Hunting is also a major threat. The total population is estimated at 1500 individuals, with a declining trend. It is believed to have become extinct in some localities in recent decades; protected areas, notably
