Emu vs. Ostrich: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 3, 2023
Emu is a large flightless bird native to Australia, while an ostrich is its African counterpart, notable for being the world's largest bird.
Key Differences
Emus, found primarily in Australia, are the second-largest birds in the world. Ostriches, on the other hand, hold the title for the world's largest bird, residing mostly in Africa.
The emu's plumage is brown with a shaggy appearance, making them adept at blending into their native Australian landscape. Ostriches showcase a more distinct feather pattern, with males bearing black and white plumes, and females presenting grayish-brown hues.
Both emus and ostriches are flightless, relying instead on their strong legs for movement. While emus can reach speeds up to 30 mph, ostriches outpace them, clocking in at around 45 mph.
In terms of temperament, emus can be curious and relatively approachable, although caution is advised around wild individuals. Ostriches, however, are known to be more unpredictable, and their powerful kicks can be dangerous if they feel threatened.
Lastly, when comparing their sounds, emus make a deep drumming noise, almost akin to a low thumping. Ostriches, contrastingly, emit a variety of sounds from hissing to booming, often resonating like a lion's roar from afar.
