            Classification
            Kingdom: Animalia
              Phylum: Chordata
                Class: Mammalia
                  Order: Artiodactyla
                    Family: Bovidae
                      Subfamily: Bovinae
                        Genus: Tragelaphus

            Tragelaphus scriptus

                  Bushbuck

            Taxonomy

            Tragelaphus scriptus [Pallas, 1766].  
            Citation: Misc. Zool., p. 8.
            Type locality: Senegal.
            The taxonomic record (above) is taken from Wilson and Reeder (1993).

            General Characteristics

            Body Length: 100-150 cm / 3.3-5 ft.
            Shoulder Height: 65-100 cm / 2.1-3.3 ft.
            Tail Length: 30-35 cm / 12-14 in.
            Weight: 25-80 kg / 55-175 lb.

            The dark brown to chestnut to hazel coat has a varied pattern of up to 7 white stripes and spots, depending on the subspecies. The face has 1-2 white cheek spots, small white stripes at the corners of the eyes, and a white muzzle. The bushy tail is white underneath. The horns are found only in the males, and grow 25-55 cm / 10-22 inches long. They are nearly straight, with one tight twist.

            Ontogeny and Reproduction

            Gestation Period: About 6 months
            Young per Birth: 1
            Weaning: After 6 months
            Sexual Maturity: At 11-12 months
            Life span: About 12 years

            Breeding occurs throughout the year.  The single young lies hidden away from its mother for the first few weeks of life.

            Ecology and Behavior

            Bushbuck may be active throughout the 24 hours of the day, although they tend to be nocturnal near human settlements.  Using trails through dense jungle, the bushbuck ranges through a restricted "home" area, which may be only a few hundred meters / yards across.  These home ranges overlap extensively, and it has been noted that the greater the population density, the smaller these home ranges are.  Savannah densities have been recorded as over 25 animals per square kilometer, while forest densities are much smaller - only 4 animals per square kilometer.  Males compete fiercely for females in estrous, but they are not territorial.  Confrontations between males are composed of displaying and charging, followed by the locking of horns and vigorous twisting in an attempt to throw the opponent off balance.  Stabbing with the horns has also been noted.  The bushbuck is an excellent jumper, clearing 2 meter / 6.5 feet tall fences with ease, and swims well.  The call resembles the bark of a dog.

            Family group: Usually solitary, although sometimes in pairs.
            Diet: Grasses as well as leaves, buds, and fruit.
            Main Predators: Leopard, lion, crocodile

            Distribution

            Open forests, bush savannas, and dense woodlands in most of Africa south of the Sahara.

            Conservation Status

            The bushbuck is not listed by either the IUCN or CITES.

            Remarks

            Tragos (Greek) a he-goat ;.elaphos (Greek) a deer; in combination referring to an antelope.  Scribo (Latin) I write, thus scriptum something written; refers to the white markings on the coat.
