Typical of the Springbuck is the 'pronk' (jumping display) which explains its common name. Both sexes have horns but those of the ram are thicker and rougher. This species has adapted to the dry, barren areas and open grass plains and is thus found especially in the Free State, North West Province and in the Karoo right up to the west coast. Springbucks move in small herds during winter, but often crowd together in bigger herds in summer. They eat grass and leaves and can go without drinking water when they have to, because they get enough moisture from the succulent leaves. It stands about 75 cm high and weighs about 40 kg. They breed throughout the year and lambs are born after a 6-month gestation period.
