The Puku (Kobus vardonii), is a species of antelope found in southern Democratic Republic of Congo and in Zambia. Pukus are found mostly in wet, marshy grassland where they eat the grass. Pukus are active in the early mornings and late afternoons.
The Puku stands about 31.5 inches at the shoulder and weighs from 154 to 176 pounds. They are sandy brown in color and the underbelly is a slightly lighter brown. The male has nearly 20 inch long ridge structured horns which are very vaguely lyre-shaped.
When scared, Puku repeat a shrill whistle sound. Females gather in herds of up to twenty individuals. During the rainy season many herds will come together for added safety, typically reaching around fifty females. Males hold territories and attempt to persuade herds of females to stay within their territories for as long as possible.
