Puku (Kobus vardonii)

Puku female close up
IUCN Red List species status – Near Threatened NEAR

Top facts

  • Only male pukus have horns.
  • When alarmed, the puku may give a shrill, repeated whistle.
  • Around 75% of the puku’s entire world population occurs in one location, in the Kilombero Valley in Tanzania.
  • Male pukus hold small territories, with each male attempting to keep herds of females on its territory for as long as possible.

Puku description

GenusKobus (1)

A medium-sized antelope, the mammals (Kobus vardonii) has a bright golden-yellow to reddish-brown coat with shaggy, somewhat curly fur along its back and loins (2) (3) (4). Its legs are uniformly reddish-brown, and it has black tips to its large, furry ears (4). The underparts and throat of the puku are white (2).

The puku has a robust, bluntly rounded head, a large black nose and black eyelashes, and white markings around the eyes and mouth. The tail has a black tuft of hair at the tip (2) (5) (6).

Horns are present only in the male puku, and are black, stout and relatively short, with heavy ridges and a slightly lyre-shaped curve (2) (3) (5) (6) (7).

Puku biology

The mammals is a social species, preferring to live in groups. Females usually live in groups around 3 to 15 strong, with their young of both sexes, while adult males typically live in bachelor groups. However, smaller herds comprising both males and females will join together during the dry season to form groups of 50 or more (5). Mature male pukus are territorial, defending small territories through which the females move (2) (7).

Pukus usually move to slightly higher elevations during the wet season, when water levels are high, and down to lower elevations closer to the water’s edge during the dry season (5). Like most antelopes, the mammals is likely to be most active in the morning and evening (7). This species grazes on grass (1) (2).

Although it may breed throughout the year (2) (5), in some areas the mammals gives birth mainly during the wet season, when most food is available and there is enough cover for the calves, which lie hidden to avoid predators (2) (11). The young are born after an eight to nine month gestation period (2) (5), but have a high mortality rate (5). Female pukus become sexually mature at about two years old, and males at about three years (2).


Puku range

The puku formerly occupied grasslands near permanent water sources in the savanna woodlands and floodplains of south-central Africa. However, its range has been much reduced and it now occurs in fragmented, isolated populations (1) (8).

Large numbers of mammalss only now occur in two countries, Tanzania and Zambia, with smaller populations in Angola, Botswana, Malawi and the southern Democratic Republic of the Congo (1) (3) (7) (8). Around 75 percent of the global puku population is restricted to the Kilombero Valley in Tanzania (1) (8) (9) (10).


Puku habitat

The mammals occupies grassland habitats near permanent water sources, including moist savanna, floodplains, and the margins of lakes, swamps and rivers (1) (3) (7). However, although it is associated with wet, swampy areas, the puku tends to avoid deep standing water (1).


Puku status

The puku is classified as Near Threatened (NT) on the IUCN Red List (1).

IUCN Red List species status – Near Threatened


Puku threats

The main threats to the mammals are illegal hunting and habitat fragmentation due to expanding human settlement and conversion into cultivated land (1) (8). The social and breeding systems of the puku are particularly vulnerable to hunting and to the disruption and fragmentation of its habitat, which can prevent successful breeding (1).

The mammals is quite easy to approach during the dry season, when it comes together in larger groups on floodplains, making it vulnerable to poaching. Unsustainable hunting is thought to have caused the loss of the puku across much of its historic range (1) (8).

In the Kilombero Valley, where the largest number of mammalss are found, this species is under threat from habitat degradation caused by overgrazing by domestic cattle, agricultural encroachment, expansion of human settlements and the conversion of nearby miombo woodland into farms and teak plantations. During the wet season, the pukus move to the boundaries of the floodplain, potentially bringing them into greater conflict with local people and cattle (9) (10). Further conversion of natural vegetation around the floodplain boundaries may reduce suitable habitat and impact on the puku’s seasonal movements (9).

In other areas, such as Lake Rukwa in Tanzania, the puku has been found to avoid habitats used by pastoralists, restricting it to the central parts of the floodplain (12).


Puku conservation

Although puku populations are scattered into small pockets in various countries, it has been estimated that about one-third of the population occurs in protected areas, the most important of which is the Kilombero Valley in Tanzania. Other areas important to the survival of the puku include Katavi-Rukwa in Tanzania, Kafue, the Luangwa Valley and Nsumbu-Tondwa-Mweru Wantipa in Zambia, and the smaller populations in Kasungu National Park in Malawi and Chobe National Park in Botswana (1) (8).

The mammals is considered a ‘flagship’ species for conservation in the Kasanka National Park in Zambia, where its population has increased after improved anti-poaching efforts (13). In Rukwa Game Reserve in Tanzania, the puku population has declined, and regular monitoring and law enforcement have been recommended (12).

As the Kilombero Valley holds most of the global population of the mammals, any future changes to this species’ status there would have a significant impact on its overall conservation status (1) (8). Within this area, the puku occurs in the Kilombero Game Controlled Area, where trophy hunting is controlled but other human impacts are not regulated (9) (10). In addition to protecting key habitats in the centre of the valley, surrounding habitat on the edges of the floodplain also needs to be conserved (9).

The Kilombero Valley is now designated as a Ramsar site, or a Wetland of International Importance (14). However, more information is still needed on the biology and behaviour of the mammals in this area, and the conservation status of puku populations in other locations also needs to be further assessed (9).
