What is the difference between emus and cassowaries?
Wattles mark the second major difference between emus and cassowaries. Emus have no wattles. Two out of three cassowary species do. The cassowary that lives in Australia has two wattles dangling from its throat.
Is the emu a cousin of the ostrich?
Still, despite their differences, emus and ostriches do have similarities, and so they remain tangentially related to each other, since they are both flightless birds that are part of the ratite group as mentioned earlier. Which practically makes them cousins.
Are all ratites related?
The tinamous’ place on the evolutionary tree offers a glimpse into the origins of flightlessness. All ratites, including tinamous, probably trace their ancestry back to a flying relative, according to Baker. Tinamous retained their ability to fly, while the other lineages each lost flight independently.
Which bird is most closely related to the cassowary?
Overall there are 60 species in this clade, while all other birds belong to the much larger Neognathae, which contains more than 10,000 species of birds. The closest relative to the cassowary is the emu, which belongs to the same order. There are three species of cassowaries and just a single species of emu.
Are emu and cassowary related?
Flightless feathered family. The cassowary is a large, flightless bird most closely related to the emu. Although the emu is taller, the cassowary is the heaviest bird in Australia and the second heaviest in the world after its cousin, the ostrich.
Is emu bigger than cassowary?
Its height is similar to the emu, but it is much heavier. While the emu might seem intimidating at 38-40kg, a cassowary’s kick has twice that weight behind it.
Is a cassowary a turkey?

Are kiwis and emus related?
Although it was long presumed that the kiwi was closely related to the other New Zealand ratites, the moa, recent DNA studies have identified its closest relative as the extinct elephant bird of Madagascar, and among extant ratites, the kiwi is more closely related to the emu and the cassowaries than to the moa.
Are emus and cassowaries related?

Which is faster emu or cassowary?
The emu might be a featherweight fighter compared to the cassowary, but what it lacks in weight, it gains in speed and agility. Instead, the emu will leave you in the dust, off at 50km per hour. This might not paint emus as the bravest of megafauna, but they’re also armed with a decent set of claws.
What are the similarities between the emu and cassowary?
Both emu and cassowary are ratite birds, i.e. they are flightless birds with large and heavyweight bodies. Both of them have unique distribution patterns, despite their similarities in physical characteristics.
How many different types of cassowaries are there?
Three species are extant: The most common, the southern cassowary, is the third-tallest and second-heaviest living bird, smaller only than the ostrich and emu. The other two species are represented by the northern cassowary and the dwarf cassowary. A fourth but extinct species is represented by the pygmy cassowary.
What is the difference between an emu and an ostrich?
The Emu is from Australia, the Cassowary is from northern Australia and New Guinea, the Ostrich is from countries in Africa, and the Rhea is from countries in South America. Their wings have no keel (anchor) on their sternum (a long flat breastbone) to connect to their wing muscles, which means that the birds can’t fly.
