IUCN Conservation Status:
Lower Risk, conservation dependent (LR/cd)
The kudu with its magnificent spiralled horns is one of Africa’s most gracious and handsome
antelope. Encounters with them are the stuff of hunters’ tales as they linger over the campfire
at night! It is the only indigenous antelope at present enlarging its distribution naturally.
Kudu first became known through Kolbe’s book on “De Kaap de Goede Hoop” in 1727. In
1764 it was known as “Le Condoma Coësdoës” after Buffon’s sightings in the Albany
(Grahamstown) district in the Eastern Cape. Evidence exists for the occurrence of “koo-doos”
in the city of Cape Town at the time of European colonization.
Although present across more than half of South Africa, the kudu received little attention from
biologists until the study of Allan-Rowlandson in the Andries Vosloo Kudu Reserve on the Great
Fish River near Grahamstown in the 1970’s. Like the impala Aepyceros melampus, the kudu
has long been recognized as a source of biltong and it is only more recently that hunting kudu
has become an outdoor adventure for stressed city businessmen. It has become a popular
luxury and is the major source of income for many landowners. Only in the mid 1990’s has
the increased trade value of rare species such as the sable antelope Hippotragus niger,
tsessebe Damaliscus lunatus, nyala Tragelaphus angasii and buffalo Syncerus caffer begun
to replace the economic value of the kudu.
Taxonomy Kingdom: ANIMALIA
Supercohort : LAURASIATHERIA
Kudu were first described from a specimen from the Kammiesberg, southern Namaqualand in
the Cape of Good Hope and were classified in the genus Tragelaphus. Its name originates
Page 3 of 22
from the Hottentot or Khoi-khoi word “ku::du”, Tragos the Greek for a he-goat and elaphos for
a deer. The species name of the greater kudu originates from strephis, the Greek for twisting,
and keras for animal horn and that of the lesser kudu from imberbis the Latin for unbearded, a
reference to the absence of a mane on the throat.
There are two species and three subspecies
Tragelaphus imberbis the lesser kudu
Tragelaphus strepsiceros the greater kudu
o T.s. strepsiceros the southern greater kudu
o T.s. bea the East African greater kudu
o T.s. cottoni the northern greater kudu
Other closely related species are
Tragelaphus spekei the sitatunga
T. eurycerus the bongo
T. angasii the nyala
T. buxtoni the mountain nyala
T. scriptus the bushbuck
T. oryx the eland.
Of these only the southern greater kudu, the nyala, the eland and the bushbuck occur naturally
in the southern sub-region of Africa.
In former times the distribution of kudu extended across Europe and Asia, their fossilised
remains being found in Pliocene and Pleistocene deposits. This indicates that the kudu may
have originated in the northern hemisphere and then only recently spread into Africa with the
African savannah or miombo-biosphere being their recent resting place. This is the most likely
explanation for the present expanding distribution. Kudu are thus still actively developing as
a species as they continuously adapt to new environments and habitats. Evidence of this
changing distribution can be seen in its spreading from
the xerophytic valley bushveld north of Grahamstown into the mesophytic valley bushveld
surrounding Bathurst, a distance of more than 50 km. In 1991 kudu were still unknown in
the area whereas today they roam freely
the xerophytic valley bushveld in the Sapkamma region to the north of Uitenhage to the
Baviaanskloof wilderness area some 80 km further south. In the mid 1970’s kudu were
unknown in this area
the false thornveld in the Cradock/Tarkastad and Graaff-Reinet regions in the early 1990’s
Page 4 of 22
to the hills in the Noupoort/Brulberg area 120 km further north by 2002
It is of crucial importance that this natural spreading should not be inhibited by governmental
translocation legislation, as it is a natural process of co-evolution with both habitat and animal
changing in relation to global warming.
In the past, the distribution of kudu in South Africa included the entire country north of the
Orange River excluding the Free State, the Lesotho Highlands and the central highveld
grassland of Gauteng and Mpumalanga. It also included Namaqualand, most of the Karoo
regions including Laingsburg, Beaufort West and Murraysburg, the southern coastal regions
Page 5 of 22
including the outskirts of the Tsitsikamma, major parts of the Eastern Cape (excluding the
former Transkei) and most of KwaZulu-Natal.
During the 1700’s and 1800’s the Eastern Cape kudu became isolated from the rest of South
Africa’s populations as a result of human settlement and retreated to the thickets of the valley
bushveld areas of the Sundays and Great Fish River valleys. At present this population is
managed as a sub-population that differs in size and trophy quality. This is a mistake, as a
genetically new sub-species is being created artificially. The kudu distribution is rapidly
reaching its former distribution due to the expansion of the game industry over the past two
decades. The present man-made gap between the Eastern Cape and Northern Cape
populations has become less than 200 km and is still shrinking. If left to natural environmental
dynamics, the two sub-populations should soon re-unite.
The shoulder height of adult cows ranges from 119-141 cm (average 134 cm) and of bulls from
128-152 cm (no average as the size depends upon the post-mature age). Adult bulls of the
greater kudu are generally 35% taller than the lesser kudu with a shoulder height of 98 cm and
double the body mass (170-300 kg vs 104 kg).
Due to differences in the climate and forage of the local habitat, kudu from the Eastern Cape
are markedly smaller than elsewhere in southern Africa. In the Eastern Cape population the
mass for 220 adult cows >3 years varies between 110 and 210 kg with a mean of 136.8 kg
compared to 155 kg for those in the eastern lowveld of the Kruger National Park.
The maximum mass for cows is reached at 4-5 years and then decreases slightly with age.
Bulls do not reach their maximum body size before the age of 12 years. After social maturity
is reached at four years, bulls continue to grow. The maximum body size/mass of 260-315 kg
is reached only at the end of their natural lifespan of between 12-16 years (280 animals.
As a result of socio-economic pressure on the southern African game industry, the natural life
span of kudu bulls has been reduced to an average of 9-11 years. This suggests that the
present southern African kudu population is becoming younger on average and that the number
of post-mature kudu is shrinking. Adult cows are totally dependent upon natural forage and
seldom live to reach the age of nine years. The majority of cows die at 6-8 years when their
body condition is declining and they are exposed to prolonged droughts with intermittent wet,
cold spells. The usual cause of death is hypothermia and pneumonia combined with the loss
Both sexes of the greater kudu have a mane that continues as a whitish dorsal crest. The
Page 6 of 22
lesser kudu does not have a mane. The greater kudu has 9-10 vertical white stripes
descending from the mane on each side of the body flank, the eastern African greater kudu 6-
8 and the northern greater kudu, 4-7. The colour of the coat differs, being a pale greyish colour
in the southern greater kudu, a comparatively richer colour in the eastern African greater kudu
and much paler in the northern greater kudu.
After eight years the coat colour of bulls becomes greyish-blue and their hair becomes dull and
less dense. The hair of the adult cow becomes dull and begins to weather away after five
years, hairless patches appearing after 6-7 years.
The underside of the short, furry, bushy tail is outstandingly white and flashes white when the
animal is in flight. This serves as a signal for other members of the group to flee with their
leader. The ears are large and mobile with a distinct white stripe on the inner edge. It is often
only the slightest flick of the white-lined ear that gives the animal’s presence away. Kudu are
cryptically camouflaged and often only an experienced eye can spot them.
The spoor of a kudu is a slightly elongated, double-hoofed print with a sharp-pointed front and
a rounded rear. The front spoor is slightly larger (5-6 x 3-4 cm) than the hind (4.5-5.5 x 3-4
cm). After eight years the spoor of mature bulls becomes more rounded at the base and less
sharp at the end, the print size increasing with age up to a maximum of 9x5 cm.

The magnificent horns are spread in beautiful open spirals. There is no scientific proof for
claims that narrow horns relate to bush dwelling or montane kudu and wide horns to plains
kudu, as the two forms are found in both habitats. However, narrow-horned kudu are more
mobile in thickets and are seen moving more frequently in thicker vegetation, whereas a wide-
horned kudu tends to conceal itself rather than to move. The horns of a kudu are constructed
in such away as to give the animal constant eye contact with the tips.
Horns are borne by males alone and although cows occasionally have horns they are under
sized or deformed. In 1888 FC Selous recorded a 37 inch female trophy with a 3.5”
circumference and a 21.875” tip to tip width.
In general, the Rowland Ward minimum qualifying trophy quality is only reached after seven
years, the quality increasing with the depth of the spiral. The horn quality can be easily
estimated by looking from tip to base along the inside core; the greater the diameter of the
spiral, the better the quality.

Kudu are widespread in the savannahs of eastern and southern Africa, ranging from Sudan
and Ethiopia in the north, to the Western and Eastern Cape in the south. Their wide
distribution indicates a high adaptability but their use of a specific habitat is reliant on the
density of woody plants, with tree and shrub density being the most critical parameter
governing their choice of habitat. Kudu are seldom found in completely open country although
they may be temporarily attracted to it by forage such as dicot broadleaf forbs and dwarf
Page 11 of 22
succulents. Trees and shrubs provide the main fodder resource as well as a refuge against
predation and protection against the cold.
It is essential that the habitat of kudu contains a high diversity of fodder plants, especially trees
and shrubs, as they do not thrive on homogenous vegetation of low diversity. During the late
1970’s and early 1980’s there were severe mortalities in the north-western bushveld areas of
the Limpopo and North-West provinces due to a high density of animals being kept on recently
enclosed land with a low diversity of woody vegetation consisting of homogenous Combretum
veld. These deaths were due to a gradual build-up of secondary metabolites (condensed
tannin) in the Combretum trees as well as a limited access to alternative fodder species. This
problem could have been avoided by lowering the kudu stocking density with efficient, pro-
active management and/or the enlargement of the land units to include more habitat variety.
Kudu prefer broken bushveld or woodland of deciduous plants with scattered thicket bush
clumps for refuge. Highly dense coastal dune thickets and evergreen forests are totally
avoided. In areas dominated by karroid vegetation or grassland, the presence of well-wooded
drainage lines and nearby mountain slopes and kloofs permits the natural expansion of kudu.
Kudu are highly sensitive to cold spells or sudden temperature changes and will move away
from lower lying areas to warmer hill slopes on cold winter nights. They also tend to move
between the aspects of topographic slopes in order to avoid prevailing winds. During hot
sunny days kudu will keep close to the shade of trees and on cold winter days stay in thicket
High mortalities are common when sudden wet, cold spells occur, especially during periods of
drought. Such mortalities were widespread in the Karoo and Eastern Cape in 1979, 1983,
1991-’92, 1996 and 2002, most deaths being adult cows aged over six years. In 1983, almost
half of the Eastern Cape kudu population died and in 1991-’92, almost 30%. The kudu
population in the Eastern Cape varied from 49 000 in 1965, to 47 000 in 1974, to a present
estimate of 120 000.
Kudu are naturally diurnal but human disturbance has forced them to become predominantly
nocturnal. During daylight hours they take refuge in closed woodland and bush thickets but in
late afternoon they move out to open broken woodland or karroid dwarf succulent plains to
feed, returning to woodland by dawn. If undisturbed they will roam for most of the daylight
Like humans, kudu display individual differences in behaviour when threatened. This makes
Page 12 of 22
them unique among the antelope species. The author noted the following behavioural
patterns of radio-collared kudu bulls in the Eastern Cape between 1994 and 2002
During culling operations, some adult bulls fled rapidly, covering a distance of 7-9 km within
20 minutes of approach by human beaters. They only returned to the home range after
3-80 days, depending on the season and the degree of disturbance
Some bulls kept a safe distance of 300-500m in front of the beaters and moved slowly in a
circle on the periphery of their home range to end safely behind the beaters
Other bulls relied on their cryptic camouflage and hid until the beaters had passed. They
then fled back to the periphery of their home range to where the beaters’ drive had started
Individuals maintained identical behaviour patterns for the full length of the study of 6-8 years.
Other groups also showed specific behaviour patterns namely
Family breeding herds generally fled in front of the approaching danger but not as rapidly
as the bulls and for a shorter distance of 50-300 m. They sometimes crossed 3-4
neighbouring home ranges but unlike the bulls, returned immediately the danger was over
Non-breeding cows and sub-adults avoided detection by circling noiselessly in short zigzag
movements and kept within the perimeters of their home ranges
Post-mature bulls hid, remaining motionless for an hour or two after the danger ended and
then gently began to move again
Feeding & Nutrition
Kudu are predominantly non-selective bulk browsers, feeding on leaves, shoots, pods or fruit
of a wide range of shrubs, trees, dicot forbs and succulents. As they are exposed to a variety
of habitats in their wide distribution range their diet differs greatly in terms of plant species
composition and there are virtually no plant species that are completely avoided. The intake
of a plant species depends upon the season and the prevailing veld condition. Kudu need a
selection of vegetation that includes
palatable, deciduous, woody plants as a dietary staple during the wet season
soft-stemmed, dicot broadleaf forbs and the new growth of woody foliage year round,
particularly during the lactation phase of cows
relatively palatable evergreen or late deciduous, woody plant foliage during the dry season
protein rich fruits and pods in the dry season
woody plants that produce new foliage in advance of the first rains. This bridges the
critical transitional phase at the end of the dry season
relatively unpalatable, evergreen woody plants that can be used as a last resort when all
other food reserves are depleted during extreme droughts, e.g. noors (a type of succulent
cactus) in the Eastern Cape xerophytic valley bushveld. An indication that the veld
condition is in its last stage of depletion is that the tips of noors shoots are eaten
Page 13 of 22
In the Eastern Cape valley bushveld the kudu diet consists of 5-12% grass, 15-18% dicot broad
leaf forbs and 70-80% tree and shrub browse. The forb to browse ratio differs greatly with
varying rainfalls and seasons. Studies in the northern savannah mixed bushveld indicated a
diet of 18% grass, 21% forbs and 61% browse.
Boomker showed that in the eastern lowveld, an adult, non-lactating kudu of 210 kg consumes
3.7 kg dried plant material per day in a dry winter and 5 kg per day in a wet summer. Thus
kudu are clearly not concentrate feeders, but are rather non-selective browsers consuming
large quantities of roughage material. There is no particular selection of young fast-fermenting
plant parts, the mean bite size measuring 3.7-4.5 cm from both old and young twig ends. Kudu
switch from foregut fermentation in a wet summer, to hindgut in a dry winter in order to
overcome the natural decline in nutritional quality, the hindgut having a greater ability to digest
Non-lactating cows require 27-33 MJ energy per day compared to 47 MJ for lactating cows.
A dietary protein intake of 9-11% and 19-23% fibre should be maintained throughout the year.
Supplementation of the diet during drought should not rely on concentrate mixture alone but
should be based on good quality lucerne in order to supply the necessary fibre. Kudu can
adapt to a gentle, slow change of climate and veld condition but are intolerant of rapid changes
in food quality.
In the Eastern Cape valley bushveld, 40-60% of adult bulls’ browsing takes place between 145-
170 cm above ground level and 40-60% of adult cows’, between135-155 cm.
A daily water intake of 7-9 litres is required for kudu in the warmer northern and western
distribution ranges. In the succulent valley bushveld of the Eastern Cape kudu rarely drink
due to the high water content of their diet.
Territory & Home range
Studies in the Eastern Cape and elsewhere in Africa have shown that kudu is not migratory or
territorial but inhabits a static home range shared by individuals of both sexes. Every
individual has a home range; this can overlap others by as much as 80%. The core of the
home range is permanent but its total area and size varies with veld condition and season.
The mean home range size is 90-350 ha during wet summer periods and may expand to 600
ha during droughts.
Kudu tend to stay in the area of their birth. If translocated within 14 months of birth a youngster
will settle, but after 14 months the birth environment becomes imprinted on its brain and it will
Page 14 of 22
try to return at all cost. For example Young experimental kudu collared in the Great Fish River
valley in 1974, were harvested by landowners in the same region some 12-14 years later. A
year-old male strangled in a live stock fence in the Kirkwood area was marked by drilling a hole
through its horn. This animal was shot as an adult nine years later in the same stock camp.
These animals remained in their areas despite a lack of restraining game fences.
If disturbed, kudu flee and either return immediately or establish a temporary, additional home
range up to 11 km away. They return to their original home range within 3-90 days and will
repeatedly return to the same temporary home range every time they are disturbed.
A study of 148 collared kudu in the Eastern Cape showed neither migratory behaviour nor
movement between home ranges for feeding purposes. Sub-adult bulls reaching social
maturity are occasionally forced out of the herd by older, mature bulls and leave to search for
a new range. These bulls are mostly responsible for the expansion of the kudus’ distribution
range as they travel for distances of up to 80 km.
During the rutting season the socially mature bulls may leave their home ranges and become
nomadic in a larger area associated with female breeding herds of adjacent home ranges.
After the rut they return to their former range. Kudu have a daily movement of between 1.5
and 3 km during wet summer months and up to 8 km in dry winter periods.
Family bonding is weak and group structures are unstable as members constantly drift between
adjacent family breeding groups. The mean number of groups overlapping and sharing the
same home range area is eight and the mean family group size 4.5, the latter size being
influenced by the degree of human interference. With the least disturbance, groups of a
maximum size of 20-35 are formed (mean 8), and with high interference are reduced to a mean
of 2.8. The group size increases during rut and in the peak calving season. During droughts
temporary gatherings of up to 60 animals can be found on open “brak”-veld areas that contain
a high level of mineral salts. This allows the kudu to supplement their diet nutrients.
The social structure comprises of
amily breeding groups of 1-2 socially mature bulls, 2-4 adult cows and 1-3 youngsters
bachelor groups of 2-6 sub-adult bulls of 2-5 years
socially mature male groups of 2-4 bulls of 5-8 years
post-mature, non-breeding male groups of 2-6 bulls over eight years
The natural population structure is
47% socially mature adult cows aged 3-9 years
Page 15 of 22
7% second year heifers aged >2-3 years
7% first-year heifers aged >1-2 years
18% socially mature adult bulls aged 2<8 years
4% post-mature trophy bulls of 8 years and older
9% male calves aged <1 year
8% female calves aged <1 year
The rut takes place from May to early July and includes 70-80% of all mating. During this time
1-2 socially mature bulls accompany each family group. In good rainfall years the rutting
period can expand to almost a full year.
Bulls reach sexual maturity at 22 months, social maturity at 4.5 years, post-maturity at 9-10
years and have an expected lifespan of 12-16 years. Outside of the rutting season the mating
bulls join mature bull groups, but will frequently leave to join family groups for a short period.
Females reach sexual maturity at 18 months and social maturity (age at first mating) at 3 years.
Thus second year heifers of 25-36 months are sexually mature but socially immature. Second
year heifers might mate during an abnormally good rainfall year but more usually only begin to
mate at 3 years. Bulls begin mating at an average age of 4.5 years. Periodic flushes of
animals with the same age occur in populations as a result of an increased growth rate from
19-28% during good rainfall years.
Gestation lasts for an average of 8.5 months and in a good year, 94% of calves are born
between late December and early March. However, in dry years only 60% are born during
this period. Sub-adult males leave the family groups at 2-3.5 years age and join bachelor
groups. Females tend to remain together in family groups for life but periodically exchange
groups. The expected lifespan for females is 7-9 years; they do not become post-mature but
keep breeding until death.
Eastern Cape kudu cows show a fecundity of 93-96%, with a mean birth rate of 84%. Only
62% of the calves survive to be weaned. Adult mortalities are generally 10-15%.
This gives a population with a natural social structure an annual long-term population growth
rate of 19-21% in a normal year. However, the growth rate can range from 13% in drought
years, to 28% in good rainfall years. The long-term production rate in the Kruger National
Park is 14.8%.
Page 16 of 22
Optimal production is attained with a mating sex ratio of one socially mature bull (>5 years) to
four socially mature cows (>3 years). Females must be cropped to maintain the adult sex ratio
of 1:4 required for achieving and sustaining productivity. Calves are normally born at a ratio
of 1.1 male to 1 female and require cropping at a proportion of 65% males to 35% females in
order to achieve the desired adult sex ratio of 1:4.
The optimum cropping ratio for an entire kudu population is a maximum of 19% of the total
number of individuals divided as follows
61% sub-adult males of aged 2-3 years
4% trophy bulls aged >8 years
35% females aged >6 years
The maternal instinct of kudu cows is poor, as mothers do not seek refuge for their calves,
forcing the calves to find their own cover. The cow returns for suckling 2-4 times daily but if
disturbed may abandon the calf for a day or two. This results in high calf mortalities, especially
during cold spells. Calves cannot jump over internal small-stock, netted fencing of 1.2 m until
they are seven months old and are abandoned when mothers are disturbed, jump the fence
and move away.
Sustainable kudu stocking rates are
40 ha/kudu (25 kudu/1 000 ha) in mixed bushveld at Nylsvley, Limpopo and in the Kruger
33 ha/kudu (30 kudu/1 000 ha) in dry mopane bushveld, increasing to 10 ha/kudu in a good
rainfall year of >380 mm
In the Eastern Cape valley bushveld, 15 ha/kudu (67 kudu/1 000 ha) at 300-340 mm
rainfall, 10 ha/kudu (100 kudu/1 000 ha) at 340-360 mm rain, 8 ha/kudu (125 kudu/1 000
ha) at 360-400 mm rain and 4 ha/kudu (250 kudu/1 000 ha) at >470 mm rain
Kudu can be stocked at 9-15 ha per animal or 70-110 kudu per 1 000 ha in an area where,
counting every six small plants (<80 cm diameter) as one, there is a density of 1 600-3 000
edible shrubs and trees per hectare. The latter must have a foliage canopy of between 50
and 170 cm feeding height and maintain >30% of their foliage throughout the year.
Kudu carcasses dress at 54-57% (86-172 kg for an adult kudu depending on age and gender).
The time for cropping or hunting having the least negative impact on production is August to
September for cows and September to December for bulls. May to July is the rutting and
lactating season and no hunting should be allowed. After September most adult cows are
more than 3.5 months pregnant and hunting is not recommended.

Kudu are highly susceptive to rinderpest, anthrax, Coryne bacterium, foot and mouth disease,
tuberculosis, pneumonia (hypothermia), cytauxzoönosis, mange and rabies. Hartwater rarely
occurs. A healthy kudu can tolerate a tick load of up to 5 000 mature ticks per animal. Tick
loads may increase tenfold when animals come under nutritional stress and will have major
negative effects on body condition.
