Emus are native to Australia, whilst ostriches are found in Africa.
Emus have darker colouring, with dark brown, grey and black fine feathers. Ostriches have thicker and lighter plumage.
An ostrich is bigger than an emu. An emu weighs between 66 and 99 pounds (30-45kg). An ostrich weighs about 300 pounds.
The ostrich is faster and is, in fact, the world's fastest two-legged animal. An ostrich can sprint at 65 Kilometres per hour (40 miles per hour) and an emu can sprint at 50 kph, or 30 mph.
Ostriches are unusual among the ratites (Flightless Birds) as they have only two toes on each foot. Emus and other ratites have three toes.
