Struthio camelus

Did you know?

  • The ostrich is part of the Struthionidae family, which is made of only ostriches and extinct species.
  • They were once known as the "camel bird."
  • They are the largest and heaviest birds in the world.
  • Their eggs are the largest eggs in the world, often weighing more than 3 pounds each.
  • A female will lay 7 to 10 eggs at a time.

Big Bird

Ostriches are the largest living birds. The males can grow up to 9 feet tall and weigh as much as 350 pounds. Ostriches use their powerful legs to kick attacking predators, or to run away at speeds of up to 40 miles per hour.

Better Together

Since they cannot fly, ostriches are forced to nest on the ground, which leaves their eggs more vulnerable to predators. To protect the eggs, females often combine their eggs into a single large nest, which is cared for by the dominant female and her mate.
