The Emu and Ostrich belong to the same class of the birds, although they differ in this regard as they belong to the different order. The Emu belongs to the Casuariiformes order, whereas Ostrich hails from the Struthioniformes. When one have to differentiate it between both these flightless birds, just by the physical appearance and movements, one founds it quite difficult as both are one of the largest birds in the world and also rest on the top of the list of fastest running birds in the world. The Emu follows the Ostrich on the second slot both regarding the large size and the speed of the running birds.
Emu is also the second fastest running bird after Ostrich.
The Emu grows up to 1.9 meters (6.2 ft). Contrary to this, Ostrich has an average height of around 6-9 feet.
Once the female emu has laid the eggs, it becomes the responsibility of the males to incubate them. Conversely, when the female Ostrich laid eggs, the female provide the incubation during the day time, and the male does incubation in the night time.
Emu is the second largest bird in the world followed by the Ostrich.
Emu has the capability to run at the speed of around 50 Kilometers per hour. On the other hand, Ostrich are the fastest running bird which can run up to 40 miles per hour (65 kilometers).
Emu
A large, flightless Australian bird (Dromaius novaehollandiae) that has shaggy brown plumage and is raised for its meat, oil, and leather.
Ostrich
Either of two large, swift-running flightless birds (Struthio camelus or S. molybdophanes) of Africa, characterized by a long bare neck, small head, and two-toed feet. Ostriches are the largest living birds.
Emu
(obsolete) A cassowary (genus Casuarius).

Ostrich
One who tries to avoid disagreeable situations by refusing to face them.
Emu

Ostrich
(ornithology) A large flightless bird of the genus Struthio.
Ostrich
The most widespread species of the genus, known as the common ostrich (Struthio camelus).
Emu
A large Australian bird, of two species (Dromaius Novæ-Hollandiæ and D. irroratus), related to the cassowary and the ostrich. The emu runs swiftly, but is unable to fly.
Ostrich
(figurative) One who buries one's head in the sand instead of acknowledging problems.
Emu

Ostrich
(golf) The hypothetical completion of a hole five strokes under par (a quintuple birdie, quadruple eagle, triple albatross, or double condor).
Emu
Large Australian flightless bird similar to the ostrich but smaller
Ostrich
A large bird of the genus Struthio, of which Struthio camelus of Africa is the best known species. It has long and very strong legs, adapted for rapid running; only two toes; a long neck, nearly bare of feathers; and short wings incapable of flight. The adult male is about eight feet high.
Ostrich
A person who refuses to face reality or recognize the truth (a reference to the popular notion that the ostrich hides from danger by burying its head in the sand)
Ostrich
Fast-running African flightless bird with two-toed feet; largest living bird
The Emu is the second largest bird in the world after the Ostrich. It has quite the similar the features as the Ostrich; these flightless birds are also the second fastest running birds. The Emu, which grows up to 1.9 meters (6.2 ft) in height also has the capability to run at the speed of around 50 Kilometers per hour. The Emu hails from the Australia, and it is the only bird alive from the genus Doramius. It will be pertinent to mention here that Emu and Ostrich hail from the same class but later gets differentiated on the basis of order, family, and genus. It is harder to distinguish between male and female emu as both have deep brown feathers and not have much of the size difference. Although, they can be differentiated from one and another easily during the mating season as the black feathers grew on the head of the female during this period. Other than this, during the mating season, the bare skin of the female emu turns blue. The emu is also the commercially important bird as products like meat, oil and leather are generated from them. They also have the soft feather which is highly demanded its usage in duster formation and as the decorative item. In the mating, season the male and female emu live along with each other for around five months, and once the female emu has laid the eggs, it becomes the responsibility of the males to incubate them.
The Ostrich are the world’s largest bird with an average height of between 6-9 feet. The other reason for Ostrich becoming famous is that they are the fastest running bird which can run up to 40 miles per hour (65 kilometers). Their features like long legs, long necks, and the small head are quite the same as of the largest Australian bird, Emu. Even then they can be easily differentiated due to their extra-large size and weight. The Ostrich hailing from the genus Struthio are now only limited to the Africa, where they live in the open grasslands called savannas. After the mating season, when the female Ostrich laid eggs, the female provide the incubation during the day time, and the male of the species does the same during night time. The male-female combination during the incubation makes up the natural camouflage. The Ostrich has quite the same diet as the emu; both of them feed on invertebrates and plants. The egg laid by the Ostrich is also recorded as the largest egg of any of the living bird; it weighs something around 1.5 kilograms.
