Ratite s and humans
Ratite s and humans have had a long relationship starting with the use of the egg for water containers, jewelry, or other art medium. Male ostrich feathers were popular for hats during the 18th century, which led to hunting and sharp declines in populations.
Ratite s are large flightless birds like the rhea and ostrich.

The emu is a ratite with small vestigial, a long neck and long, strong legs with three forward directed toes. It is the largest native bird of Australia. It stands about 180 cm tall, height of the back is about 1 m, and the body-weight may reach 55 kg.
The shading illustrates the diver sity of this group - the darker the colour the greater the number of species. Data provided by WWF's Wildfinder.
Since ratite s do not fly. they no longer need a keel. Other ratite s include cassowaries, kiwis, moas and emus.
Unlike the ratite s, to which they are most closely related, tinamou s have a breastbone and can fly. Their flight however is not strong, and they are adept runners. Their main response to danger is to remain perfectly still allowing their cryptic colouration to protect them.
The kiwi is generally nocturnal (most active at night). It belongs to the group of ratite s, flightless birds that also include the ostrich. emu. and rhea. There are 6 species of kiwi (genus Apteryx ). The kiwi is in danger of extinction.

Like its larger cousins the cassowary. emu. ostrich. and rhea. the kiwi is classified as a ratite. Most birds have a special ridge on their sternum, called a keel, where flight muscles attach, but ratite s don't need keels because they don't fly.
The Ostrich belongs to the Struthioniformes order of (ratite s). Other members include rheas, emus, cassowaries and the largest bird ever, the now-extinct Elephant Bird (Aepyornis).
Flightless and Loving it: Their adaptation to a terrestrial life is extensive: like all ratite s they have no keel on the breastbone to anchor wing muscles, and barely any wings either: the vestiges are so small that they are invisible under the kiwi 's bristly, hair-like, two-branched feathers.
The rheas belong to a group of birds known as ratite s which includes the Ostrich (Struthio camel us) from Africa, the Cassowary (Casuarius casuarius) and Emu (Dromaius novaehollandiae) from Australia and kiwis (Apteryx spp.) from New Zealand.
They are a member of the ratite family with ostrich es and emus. They have three claws on each foot. With their powerful legs they can either out run or kick at a potential predator. They have even been known to attack people on horseback.

The term 'ratite ' as it applies to the area of agriculture can be defined as ' A family of large flightless birds that include ostriches, emus, and rheas, which U.S. farmers are beginning to domesticate and raise for food. Ratite inspection has become a policy issue because producers want USDA to include them under the mandatory meat and poultry inspection laws. If plants that slaughter and process these birds were under mandatory inspection, most of the cost would be covered by taxpayers. Currently, such plants must pay for USDA inspection on a fee-for-service basis, under a voluntary ratite inspection program instituted in 1995 under authority of the Agricultural Marketing Act of 1946'.
The term 'ratite ' as it applies to the area of general science can be defined as 'of, like or pertaining to flightless birds'.About the author
