Puku

The puku (Kobus vardonii) is a medium-sized antelope found in wet grasslands in southern Democratic Republic of Congo, Namibia, Tanzania, Zambia and more concentrated in the Okavango Delta in Botswana. Nearly one-third of all puku are found in protected areas, zoos, and national parks due to their diminishing habitat.

Description
Puku stand about 80 cm at the shoulder and weigh from 70 to 80 kg. The puku is sandy brown in colour, with the underbelly a slightly lighter brown. The coat is rougher than that of the similar-sized southern reedbuck, lechwe or impala, or the smaller oribi. Males have horns which are ridge-structured, 50 cm long, and lyre-shaped.

Subspecies
There are two subspecies, the Senga Puku (Kobus vardonii senganus) and the southern puku (Kobus vardonii vardonii).

Ecology
Puku are found almost exclusively in marshy grassland and dambos, where they eat grasses. The puku diet is flexible in regards to type of grasses consumed. There is little dietary competition with other bovids. This species is crepuscular, active in the early morning and late afternoon. When scared, puku repeat a shrill whistle sound. Females gather in herds of up to 20 individuals. During the rainy season, herds will come together for added safety, typically reaching around 50 females. Males hold territories and attempt to persuade herds of females to stay within their territories for as long as possible. In the wet season, due to large floods in their habitat they migrate to a higher elevation and in the dry season remain near water.
