The Blue Wildebeest (Connochaetas taurinus) is particularly associated with open woodland and grassland where there is water. They are dependent on water and in the Etosha National Park they survive the dry winter months by drinking at the artesian springs and water holes along the edge of the pan. Adult males have a shoulder height of about 1.5 m (5 ft) and a mass of about 250 Kg (551 lb). The animal is also sometimes called the Brindled Gnu.
The wildebeest mating season is called a rut and the males establish temporary territories and try to entice females with grunts and distinctive antics. Competition between males consist of displays, loud grunting calls and shoving with the horns. Blue Wildebeest usually breed at the end of the rainy season - between April and June - when the animals are fittest.
