The scientific name for flightless birds is ratites. This group includes birds like ostriches, emus, rheas, kiwis, and cassowaries. Ratites are characterized by their lack of keel on the sternum bone, which is necessary for flight muscle attachment.
Emus and cassowaries primarily rely on their size and strength for self-defense. When threatened, they can deliver powerful kicks with their long legs, which can inflict significant damage on predators. Additionally, cassowaries have sharp claws that can also be used defensively. Both birds tend to use their speed and agility to escape from danger when possible.
