Flightless Birds have skeletal adaptations that reflect their lack of flight, often featuring heavier, sturdier bones to support their body weight on the ground. Unlike flying birds, flightless species typically have reduced or absent keel bones, which in flying birds serve as anchor points for powerful flight muscles. Additionally, flightless birds may have more robust leg bones for running or walking, while flying birds have lighter, more streamlined bones to facilitate flight. Overall, these differences illustrate the evolutionary adaptations each type of bird has made to their respective lifestyles.

Ducks are not flightless. In some places, ducks are migratory birds, flying long distances in winter.
There are many different drawings of flightless birds. Some of these drawings reflect birds who naturally cannot fly such as penguins for example.
Australia does not have ten flightless birds. Only the emu and the southern cassowary are truly flightless.
