The ostrich is the largest and heaviest bird in the world: adult males can grow up to two and a half meters tall and weigh more than 150 kilos.
Here in South Africa, the domestication and breeding of ostriches is fundamentally intended for the production of meat, skin, feathers and eggs.
Improvised safaris on some farms allow tourists to practice a funny and rather unusual sport: ostrich-riding.
The wings are very small and do not allow them to fly, but they do help in propulsion, for balance when running, and also to fend off potential predators.
Their long, powerful, muscular legs are designed for running and help them reach speeds of up to 90 km/h.
