ANIMAL FACTS - Ratites
Although they have feathers, emus cannot fly because their wings are too small. Also due to the structure of the feathers they are no longer capable of creating lift.
The Ratite family includes flightless birds with a flat, keelless breastbone (the keel is where the flight muscles connect). Most of their muscle is in their legs and thighs. There are only five species around the world. Cassowary, Emu, Ostrich, Rhea and Kiwi.
