Etymology

The term 'ratite' comes from the Latin word 'ratitas,' meaning 'flatness,' referring to the flat breastbone of these birds, which lacks the keel that allows for flight.
The word was first used in the late 19th century to define this group of birds.

Biology

Ratites have a unique structure in their bones, which includes a primitive skeletal design believed to be closer to ancient birds.
Their feathers are more akin to hair than the typical feathers found on flying birds, providing insulation rather than lift.

The emu and cassowary are also part of this group and are found primarily in Australia and New Guinea.

Conservation Status

Many ratite species are threatened or endangered due to habitat loss, hunting, and introduced species.
The flightless nature of these birds makes them particularly vulnerable to predators introduced by humans.
