Bongo at the Louisville Zoo

Bongo

RANGE

Mountain forest of equatorial Africa, from West Africa to Kenya and Uganda.

HABITAT

Dense brushwood in lowlands and mountain forests.

SIZE

Largest of the forest antelopes. Males are slightly larger than females. Get
5.5 – 8 feet in length.

REPRODUCTION

Females come into heat approximately every three weeks. Gestation is about
285 days (9.5 months).

DIET

Wild: Browsers; eat leaves, flowers, twigs, thistles, shoots, fruit. Said to pry
bush and tree roots out of the ground with their horns.
Zoo: Hay and a mixture of grains.

BEHAVIOR

  • An elusive antelope. Seldom seen in wild, preferring to live in the densest, most remote jungle areas.
  • Live singly, in pairs, or in small groups.

POINTS OF INTEREST

  • Old males are very dark chestnut while the head, neck and underpart are almost  black.
  • Males’ coats darken with age.
  • Both males and females have spiraled horns.
  • Bongos usually run with their heads thrown back and their horns parallel to their back. This streamlining effect parts the bushes while they run and allows the foliage to spring back, making tracking the  bongo almost impossible.
  • The only forest antelope to form herds.
  • They have been known to eat burned wood after lightning storms. This behavior is  believed to be a means of getting salt or minerals.
  • Bongos are great high jumpers but prefer to go under or around obstacles.
  • Bongos use their prehensile tongue to grasp the vegetation they feed on.
  • As browsers they are important to their habitat by keeping vegetation from becoming overgrown.
  • They are preyed upon by leopards and sometimes hyenas.
