Fun Facts

  1. One ostrich egg equals up to 24 chicken eggs. And it takes approximately 2 hours to boil!
  2. Ostriches can run up to 70 kph (40 mph) and can outpace most pursuers, such as lions, leopards, and hyenas.
  3. It is the largest and heaviest living bird. It is unable to fly and does not possess a keeled sternum (breastbone) common to most birds.
  4. Ostriches stretch out their neck and lay their head on the ground to keep from being seen, hence the myth that ostriches hide in the sand.
  5. Ostriches are so powerful that a single kick at a predator, such as a lion, could be fatal.
  6. A female ostrich shows a remarkable ability to recognize her own eggs even when mixed in with those of other females in their communal nest.

Ecology and Conservation

Humans have had a close relationship with ostrich for thousands of years. Ancient Egyptians farmed ostrich and present day farming, which began in 1833, is run much the same way. Ostrich feathers have been used for adornment by humans for at least 5000 years and the eggs are still used by Bushmen as jewelry and receptacles for carrying water. Extensive hunting for feathers, meat, and skin coupled with overgrazing by domestic animals on their habitat has lead to the near extinction of the ostrich from the Middle East and North and South Africa. Although they are not globally threatened, the 4 subspecies of ostrich require strict protection and farming has helped to conserve the wild populations.
