Lesser Kudu

Tragelaphus imberbis


Description

he lesser kudu is a spiral-horned antelope. The head-and-body length is typically between 110 and 140 cm (43 and 55 in). Males reach about 95–105 cm (37–41 in) at the shoulder, while females reach 90–100 cm (35–39 in). Males typically weigh 92–108 kg (203–238 lb) and females 56–70 kg (123–154 lb). The bushy tail is 25–40 cm (9.8–15.7 in) long, white underneath and with a black tip at the end.

Distinct signs of sexual dimorphism are seen in the antelope. The male is considerably larger than the female. The females, as well as juveniles, have a rufous coat, whereas the males become yellowish grey or darker after the age of two years. The male has a prominent black crest of hair on the neck, but this feature is not well-developed in the female.[6] One long white stripe runs along the back, with 11–14 white stripes branching towards the sides. The chest has a central black stripe, and there is no throat beard. A black stripe runs from each eye to the nose and a white one from each eye to the centre of the dark face. A chevron is present between the eyes. The area around the lips is white, the throat has white patches, and two white spots appear on each side of the lower jaw. The underparts are completely white, while the slender legs are tawny and have black and white patches.The lesser kudu is characterised by large, rounded ears. Its tracks are similar to the greater kudu's. Females have four teats. The average lifespan is 10 years in the wild, and 15 years in captivity. 

Horns are present only on males. The spiral horns are 50–70 cm (20–28 in) long, and have two to two-and-a-half twists. The base circumference is 156–171 cm (61–67 in). The slender horns are dark brown and tipped with white. Male young begin developing horns after six to eight months, which reach full length after three years


Fun Facts

The lesser kudu is mainly active at night and during the dawn, and seeks shelter in dense thickets just after the sunrise. It can camouflage so well in such dense vegetation that only its ears and tail can indicate its presence. The midday is spent in rest and rumination in shaded areas.The animal spends about 35% of daytime foraging, 36% standing and lying, and 29% in roaming. As the thinnest tragelaphine, the lesser kudu can move through dense vegetation with ease.

The lesser kudu is a shy and wary animal. When alarmed, the animal will stand motionless, confirming any danger. If it senses any approaching predator, it will give out a short sharp bark, similar to the bushbuck's. The lesser kudu would then make multiple leaps of up to 2 m (6.6 ft) height with an upraised tail. If captured by the predator, the victim gives a loud bleat. The lesser kudu is gregarious in nature.

No distinct leader or any hierarchy is noted in the social structure; with no territorial behavior, fights are uncommon. While fighting, the lesser kudus interlock horns and try pushing one another. Mutual grooming is hardly observed. Unlike most tragelaphines, females can be closely associated for several years. One to three females, along with their offspring, may form a group. Juvenile males leave their mothers when aged a year-and-a-half, and may form pairs.

However, at the age of four to five years, males prefer a solitary lifestyle and avoiding one another, though four or five bulls may share the same home range. Lesser kudu do not usually associate with other animals, except when they feed in the same area. A pure browser, the lesser kudu feeds on foliage from bushes and trees, shoots, twigs and herbs. It also eats flowers and fruits if available, and takes small proportions of grasses, usually in the wet season.

Despite seasonal and local variations, foliage from trees and shrubs constitutes 60-80% of the diet throughout the year. Foliage from creepers and vines (such as Thunbergia guerkeana and some species of Cucurbitaceae and Convulvulaceae) forms 15-25% of the diet in the wet season. Fruits are consumed mainly in the dry season. Olfactory searching, much in the same posture as grazing, is used to find fallen fruits (such as Melia volkensii and Acacia tortilis), while small fruits (such as Commiphora species) are directly plucked from trees.

The size and structure of its stomach also suggests its primary dependence on browse. The lesser kudu browses primarily at dusk or at dawn, and is associated with the gerenuk and the impala. The lesser kudu and the gerenuk might compete for evergreen species in the dry season. However, unlike the gerenuk, the lesser kudu rarely prefers Acacia species and does not stand on its hindlegs while feeding. The lesser kudu does not have a great requirement for water, and can browse in arid environments. It eats succulent plants, such as the wild sisal, Sansevieria, and Euphorbia species in the dry season, and drinks water when sources are available.
