Ostriches and Emus are counted among the largest flightless birds. Both of them have strong muscular legs, heavy body and long neck.

Did a question ever crossed your mind, who would win if they come face to face and a battle happen between them?

However, their geographical distribution doesn’t overlap; they are found in different halves of the world.

To determine the winner we need to closely look into their different characteristics such physical traits, behaviour, diet, habitat etc.

Let’s know about them.

What are the physical characteristics of Ostrich?

Ostriches are the largest birds in the world. They have a small head, short bill, long neck, heavy body, and strong legs and are flightless.

Emus can attain a height of about 6.5 feet and weigh around 36-40 kg. Male and female emus look alike;

they have brown feathers however, females are slightly bigger than their male counterparts.

Now they are found in Sub-Saharan Africa.

Where emus are found?

Emus are native to the Australian continent.

In what habitat ostriches live?

Ostriches are found in savannah, dry-sandy desert regions of central and southern Africa.

Which type of habitat emus live in?

Emus live in varied habitats of Australia such as savannah, grasslands and subtropical climate; generally, they prefer to live close to the water bodies.

Amazing facts:

  • Emus are the only birds that have calf muscles.
  • Ostriches have 3 stomachs each having a different function.
  • As ostriches don’t have teeth they swallow pebbles to grind their food inside their body.
  • An adult ostrich carries about 1 kg of stones in its stomach.
  • Ostriches are very fast runners; they can run at a speed of about 70 km/h and can cover 5 m in a single step.
  • The Wingspan of Ostrich is about 2 metres long.
  • Both male and female ostrich incubates eggs during a different time of day; during day females incubates while in night male ostrich incubates eggs.
  • Emus have two sets of eyelids; while one is used for blinking other is used to keep eyes safe from the dust.

Combat: Bird Fight: Ostrich vs Emu

According to above information, we know that Ostrich and Emus are very distinct birds.

However, if a face-off happens between them we predict Ostrich would win.

Ostrich already has size and weight advantage; if an ostrich charge on Emu then Emu can only run away leaving the battle.

Even if Emu dares to attack ostrich; then ostrich is able to inflict heavy injuries which might prove to fatal to Emu.

Hence, Ostrich is the unopposed winner of this battle.
