As someone who loves learning about wildlife, I’ve always been intrigued by the ostrich and the emu—two of the largest flightless birds in the world. I remember visiting a wildlife sanctuary where I had the chance to see both up close. The sheer size and speed of the ostrich was jaw-dropping, while the emu’s calm and curious nature was fascinating to observe. Even though they’re often compared due to their similarities, I realized they have distinct differences that make them each unique.
In this article, I’ll share a deep dive into the ostrich vs emu comparison, exploring everything from their physical traits to their behavior, diet, and more.

1. Ostrich vs Emu Size
When comparing the size of these two birds, ostriches reign as the largest birds on Earth. Emus, while large, are notably smaller.
| Attribute | Ostrich | Emu |
|---|---|---|
| Average Height | 7-9 feet (2.1-2.7 meters) | 5-6.5 feet (1.5-2 meters) |
| Average Weight | 220-350 pounds (100-160 kg) | 80-130 pounds (36-60 kg) |
- Ostrich: Ostriches are known for their imposing size. Their height and weight make them a dominant presence in the animal kingdom.
- Emu: Emus, while still large, are less massive. However, they are the largest bird native to Australia.
2. Ostrich vs Emu Speed
Both ostriches and emus are fast runners, a necessary trait for survival in their respective environments. But who wins the race?
| Attribute | Ostrich | Emu |
|---|---|---|
| Top Speed | Up to 45 mph (72 km/h) | Up to 30 mph (48 km/h) |
- Ostrich: Thanks to their long, powerful legs, ostriches are the fastest-running birds on land. They can outrun most predators.
- Emu: While not as fast as the ostrich, emus are still quick runners, helping them navigate Australia’s rugged terrain.
3. Ostrich vs Emu Diet
Despite their similar appearances, ostriches and emus have different dietary habits.
| Diet Type | Ostrich | Emu |
|---|---|---|
| Primary Diet | Omnivorous (plants, insects) | Omnivorous (plants, insects) |
| Unique Foods | Small reptiles, locusts | Seeds, flowers |
- Ostrich: Ostriches are omnivores, feeding on a mix of plants, insects, and small animals like lizards or rodents.
- Emu: Emus primarily feed on plants, seeds, and insects. They prefer fruits, flowers, and seeds but will eat insects if they are abundant.
4. Ostrich vs Emu Habitat
The habitats of ostriches and emus are vastly different, with each species adapted to survive in their unique environments.
| Habitat | Ostrich | Emu |
|---|---|---|
| Native Region | Africa (savannas, deserts) | Australia (grasslands, savannas) |
- Ostrich: Ostriches are native to Africa, commonly found in open savannas and arid deserts. They thrive in areas where they can see predators coming from a distance.
- Emu: Emus, on the other hand, are native to Australia. They prefer the grasslands, woodlands, and savannas where they can find abundant vegetation to graze on.
5. Ostrich vs Emu Behavior
Both birds are non-aggressive but will defend themselves when threatened.
- Ostrich: Ostriches are known to kick with immense force when threatened, using their powerful legs to fend off predators.
- Emu: Emus rely more on running to escape threats. Their long strides and agility help them quickly move away from danger.
6. Ostrich vs Emu: Lifespan
| Lifespan | Ostrich | Emu |
|---|---|---|
| Wild | 40-45 years | 10-20 years |
| Captivity | Up to 50 years | Up to 35 years |
- Ostrich: With fewer natural predators in controlled environments, ostriches can live up to 50 years in captivity.
- Emu: Emus generally have a shorter lifespan, living around 10-20 years in the wild and up to 35 years in captivity.
Conclusion
After having the opportunity to see both an ostrich and an emu in person, I truly came to appreciate their differences. The ostrich’s towering height and lightning-fast speed were incredible to witness, while the emu’s more relaxed and solitary nature had its own charm. While they may both be large, flightless birds, each species has adapted uniquely to its environment and lifestyle. If you ever get the chance to see them in the wild or at a sanctuary, take a moment to appreciate these fascinating creatures. For me, learning about the differences between the ostrich vs emu has only deepened my fascination with the natural world.
