Taxonomy
The taxonomy of bushbuck, and of the Tragelaphini
The tribe Tragelaphini (sometimes referred to by some authors as "Strepsicerotini"), or the spiral-horned antelopes, are bovines that are endemic to sub-Sahara Africa. These include the bushbuck, kudus, and the elands. The scientific name is i ...

northern subspecies (''T. s. scriptus'') and a southern subspecies ''T. s. sylvaticus''. In the 1780 original description of ''T. sylvaticus'' from the Cape Region by Sparrman, no mention was made of striping. According to Moodley ''et al''., males of type populations in West Africa

are more often striped than southern and eastern specimens,[ although this is not always the case.
In 2011, Groves and Grubb advocated recognising eight species of bushbuck: ''T. scriptus'' (Pallas, 1766); ''T. phaleratus'' (Hamilton Smith, 1827); ''T. bor'' Heuglin, 1877; ''T. decula'' (Rüppell, 1835); ''T. meneliki'' Neumann, 1902; ''T. fasciatus'' Pocock, 1900; ''T. ornatus'' Pocock, 1900; and ''T. sylvaticus'' (Sparrman, 1780), grouped in a northern and southern 'group'. The Ethiopian endemic species known as Menelik's bushbuck or ''decula'' was classified as a ''scriptus'' group species as opposed to Woodley. In the case of '']Tragelaphus

'', these 'species' would be based mostly on geography and pelage as opposed to genetics. These proposals are controversial.
In 2018, Hassanin et al. published a molecular phylogenetic study that provided support for the ''scriptus'' and ''sylvaticus'' species, with a divergence time of at least 2 million years, albeit with considerable genetic diversity within each of these groups.
Description
Bushbuck stand about at the shoulder and weigh from (depending on sex). They have a light brown coat, with up to seven white stripes and white splotches on the sides. The white patches are usually geometrically shaped and on the most mobile parts of their bodies, such as the ears, chin, tail, legs, and necks. The muzzles are also white. Horns, found only on the males, can reach over half a metre and have a single twist. At 10 months old, young males sprout horns that are particularly twisted and at maturity form the first loop of a spiral.

'') and various other plants. Bushbuck are active throughout the day, but tend to be nocturnal near human habitations.
Bushbuck are solitary animals, but are not aggressively antisocial, and individuals sometimes forage in close proximity. Bushbuck live within a "home" area, which is usually around 50,000 m2 on the savannah and much larger in the forest, that they will not normally leave. These areas usually overlap other bushbuck home areas.
