Lesser Kudu

Tragelaphus imberbis

Female lesser kudus will form small groups of twos or threes; males sometimes form small bachelor groups, but are typically solitary.  Mature males and females are easy to tell apart. They are sexually dimorphic (sexes have different characteristics) with the males having a grey-brown hide and horns, while females have a reddish-brown hide and no horns.

Adaptations

  • Lesser kudus have cryptic coloring (coloring which allows them to blend with their environment) provides excellent camouflage in the scrublands that make up their habitat.
  • Kudus enhance the effectiveness of their camouflage by remaining motionless for long periods of time, making them hard to spot.
  • These antelopes have large ears and fantastic hearing to help the detect predators.
  • Kudus use a warning bark to warn others of the presence of predators when threatened.

Physical Description

  • Kudus are spiral-horned antelope where males have horns that twist 2.5 times, form a chevron pattern above their heads, and may reach 3.5 feet (60-105 cm) in length.
  • They are sexually dimorphic (sexes have different characteristics) with the males having a grey-brown hide and horns, while females have a reddish-brown hide and no horns.
  • Males are also larger than females, standing about 37-41 inches (95-105 cm) at the shoulder and weighing 203-238 pounds (92-108 kg). The smaller females stand about 35-39 inches (90-100 cm) and weigh 123-154 pounds (56-70 kg).
  • Both sexes have a white stripe running down the back with 11-14 branches that run down the kudu’s sides.

Diet

What Does It Eat?

In the wild:
Kudus feed on the leaves, twigs, grasses, herbs and fruits found in their habitat.

At the zoo:
Alfalfa hay, wild herbivore grain, browse (plants) and produce

What Eats It?
Lions, leopards, wild dogs, and spotted hyenas all prey on these antelopes.  These antelope are also hunted by humans.

Social Organization

Female lesser kudus will form small groups of twos or threes; males sometimes form small bachelor groups, but are typically solitary.  Kudus do not express any territorial behaviors and fights are rare, typically only seen in breeding season.  Kudus of both sexes will stand on their hind legs and take part in shoving contests. Kudus browses the scrubland bushes at dawn and dusk, seeking shelter in the dense brush during the daytime.

Life Cycle

With no set breeding season, rutting males test the urine of all females they approach to determine their readiness to breed.  Females carry their offspring for 6-8 months before segregating themselves to deliver a single calf weighing 16.5 pounds (4 to 7.5 kg).  These calves remain hidden in grasses while their mothers forage for about 4 weeks. After that initial period, they gradually spend more time with their mother until they are weened at around 6 months.  Fifty percent of calves do not survive to six months and if they survive, will reach sexual maturity at 15-18 months.  Males do not commonly reproduce until 4-5 years when they achieve the required social status to be successful.  Kudus have a lifespan in the wild of 10-15 years and may reach 20 years in captivity.
