Special Adaptations

  • The emu is an omnivore (eats animals and plants), eating constantly when food is available and storing the reserves as fat to be used when food is scarce.
    • The male uses these reserves when tending to the eggs and will not eat during this time.
  • To help digestion, the Emu swallows small pebbles that grind its food.

Ratite Facts

    • Other birds included in the ratite family include ostriches, rheas, kiwis, moas, and more.
    • In addition, emu wings are reduced in size and are not capable of enough lift to carry the bird.
    • Emus do not have flight feathers, but have evolved a downy coat.
